Since the turn of the century, Thomas & Betts has been a recognized
leader in electrical fittings. Industry standards such as Chase®
Nipples and Erickson® Couplings were introduced by Thomas &
Betts and are still registered trademarks. This leadership continues. Here’s why.
Innovative Designs
The real test of product design of electrical fittings lies in
two areas: Job-suited installation and life of the job reliability. Thomas & Betts Fittings provide both because
we listen. We listen to problems and suggestions
from the field. Most of the products in this section
result from the good suggestions of knowledgeable
electrical people. Many were customer specials to
solve particular installation and performance problems. You can benefit from their experience.
Approvals and Listings
Electrical raceways require accessory fittings that
provide the mechanical strength, ground continuity, and environmental integrity of the system. As
new raceways have been introduced, Thomas &
Betts engineers have designed fittings which
meet the requirements of the National Electrical
Code as well as the listing requirements of the
Underwriters’ Laboratories and the Canadian
Standards Association. You can use Thomas &
Betts Fittings with confidence.
High Performance Products
Quality and performance result when engineering
design skills are combined with the manufacturing
technologies required to produce them. The Thomas
& Betts Fittings in this section are produced from many
materials and by many manufacturing methods, each
carefully selected for its end use suitability. This combination gives you the reliable performance you expect from
Thomas & Betts Raceway Fittings.
Lower Installed Cost
It is a function of purchase cost, availability, installation advantage, and
performance. Lower installed cost comes in every carton of Thomas &
Betts Raceway Fittings.

DURA-PLATE™ Corrosion Resistant
Fittings have a T&B plating process
that provides excellent corrosion resistance on threaded steel and malleable
iron fittings for use in harsh environments.
DURA-PLATE™ Corrosion Resistant
Fittings utilize an electro-plating
process which insures a uniform thickness of protective material over the
entire part. Conventional hot dip coatings deposit an uncontrolled build-up
of material on the part, especially in
threaded areas. This excess build-up
must be removed to allow mating parts
to function.
The process of removing this build-up
in the threads in turn damages the
coating and compromises the effectiveness of the protection.
An additional drawback of hot dip
coating is the lower ductility of the
alloyed interface layer which is formed
during the hot dip process which can
cause spalling if the item is deformed
after coating.
In addition to the uniformity of the coat-

ing, the distinctive gold color of the
plating allows immediate recognition
that the part has been prepared for
exposure to harsh environments and
confirms the extra protection by visual
inspection.
DURA-PLATE™ Corrosion Resistant
Fittings have been subjected to salt
spray tests conducted according to
ASTM Specification B-117. The results
of Corrosion Resistant Fittings tests,
along with galvanized parts, appears
below:
Ordering Information
• Add the prefix “040-” to the standard
catalog number; for example a 5332
with DURA-PLATE™ Corrosion
Resistant Fittings protection would be
ordered as “040-5332”.
• Check for catalog numbers in stock.
• Allow 6-8 weeks for delivery, on nonstock items.
• Add 20% to price of standard item.
• Minimum order is standard package

“Case Hardened Locknuts”
Case hardened locknuts make fittings faster and easier to install. Case
hardened locknuts do not slip or turn
thereby protecting the biting edge.
Case hardened locknuts bite through
paint into the enclosure providing
excellent continuity of ground (typical
T&B/Thomas & Betts fitting with case
hardened locknuts successfully passed
minimum fault current of 10,000 amps
RMS). Case hardened locknuts when
assembled in the intended manner will
not vibrate loose thereby insuring excellent ground continuity.

Blackjack ® – Grounding Bushing
Innovative design makes installation

The Blackjack® Grounding Bushing
never has to be threaded onto a
conduit. It is simply placed in position
on either a threaded or non-threaded
rigid or IMC conduit, with the grounding lug in perfect position to accept the
grounding wire. Even in tight installations.
It’s as simple as one, two, three.
Compare the installation with conventional bushings that must be threaded
onto the conduit. In tight areas, you

may have to remove the grounding lug,
keep up with the loose parts, and then
reattach the lug. Then you still have to

The Blackjack bushing does away with
these needless delays for good, making it the ideal grounding bushing. And

Application
• To connect threaded metal conduit
(ferrous rigid/non-ferrous rigid/PVC
coated/or intermediate metal) to a
threadless opening in a box or enclosure in outdoors or indoor location
exposed to continuous or intermittent
moisture.
• To positively bond conduit to box or
enclosure.

(For Threaded Rigid Metal Conduit/IMC/PVC Coated Rigid Metal Conduit)

Features
• Rugged steel/malleable iron/copper
free aluminum construction.
• Tapered internal threads for watertight/dust tight union (A).
• Threads relieved to prevent bottoming of conduit ensuring sound
assembly (B).
• Recessed sealing ring at box end.
Sealing ring captivated (C).
• Hardened steel/malleable iron/copper free aluminum locknuts designed
to provide high quality ground continuity; extended reach of locknut permits clamping on thin boxes and
enclosures (D).
• Insulated throat, insulates conductors,
prevents abrasion and thinning of
conductor insulation, reduces wire
pull effort (E).
• Suitable for hazardous location use
per following:
(i) Class I Division 2, Class II
Division 1 & 2, Class III Division
1 & 2 per N.E.C. 501-4 (b); 502-4
(a) and 503-3 (a).

(ii) Class II Groups E, F, G, & Class
III locations per CEC 18-202; 18252; 18-302; 18-352.
• PVC coated 485 Series
(i) Protects connector from
extremely corrosive surroundings
without affecting integrity of electrical grounding path (F).
(ii) Provided with overlapping sleeve
for additional seal (G).
National Electrical Code states that,
“Where practicable, dissimilar metals
in contact anywhere in the system shall
be avoided to eliminate the possibility
of galvanic action”, the only exceptions
Aluminum fittings and enclosures, are
permitted to be used with steel conduit.
Joint Industrial Council (JIC)
Electrical Standards also forbid dissimilar metals in contact for the same reason and require that the fittings for
metal conduit be of malleable iron or
ductile iron and have impact strength
comparable to that of the conduit.
“Copper Free Aluminum”
Copper free aluminum castings for
fittings have a maximum of 0.4% copper. The most detrimental effect of
higher percentage of copper on aluminum base alloy is its decrease in
corrosion resistance.

Rigid and Intermediate Metal Conduit Fittings
2 Locknut Design with peripheral
slots and a hexagonal/angled spline
spaced every 30° enables easy
application of torque with wrench or
hammer and screwdriver. (See
Figures 2 & 3)

Never before has a single hub fit like this
one. Designed for unequalled performance. The innovative engineering of
the T&B® Hub will, quite simply, raise
your performance expectations for
threaded hubs.

3 Sharper and Deeper Teeth on locknut and body designed for a more
penetrating bite for improved bonding to the enclosure.
4 Hexagonal/Splined Body Design
for fast, easy installation with wrench
or hammer and screwdriver.
5 Precision Machined Tapered
Threads designed to create watertight union.
6 Insulated Throat molded from 105°
C rated thermoplastic with a flammability rating of 94 V-O.

1 Sealing Ring And Groove with innovative profile outperforms standard
‘O’ ring design. Sealing ring is captivated in place before installation and
resists buckling or slipping during
installation. The seal groove is
designed for optimum compression
of the sealing ring. The sealing ring is
designed to provide a complete 360°
seal, even when the conduit is not
perpendicular with the enclosure.

Jumper

Whenever you install a rigid
expansion coupling in a long conduit run, you normally need three
hands, two strong backs and lots
of patience. Now you can relax.
T&B introduces the new, no-hassle Rigid Conduit Expansion
Coupling. Installation’s just a few
turns and you’re done. The T&B
Rigid Conduit Expansion Coupling
features innovations that provide
conveniences to the installer, saving time and money on the job.
There’s no disassembly needed
during the installation, requiring
fewer tools and less opportunities
for lost pieces.
The new XJG-TB Rigid Conduit
Expansion Coupling also packs an

added punch: It’s the only fitting of
its kind that features a true internal
bonding jumper. This eliminates
the need for additional external
bonding jumpers, so there’s fewer
parts to buy and install.
If you need a fitting that can give
and take without a lot of hassle,
reach for T&B’s new XJG-TB Rigid
Conduit Expansion Coupling. It’s
the latest breakthrough in the
industry’s leading line of conduit
fittings. Contact your local representative for more information
regarding the XJG-TB Rigid
Conduit Expansion Coupling and
the complete line of conduit fittings from the name you trust for
quality design and manufacturing,
Thomas & Betts.

Slide the fitting onto the conduit
until it stops at the internal sliding
bushing. Tighten and you’re
ready. No parts to reassemble!

Innovative Design Makes
Installations Easier.
• No disassembly necessary to install
• Fast, simple, and requires fewer steps
• True Internal Bonding Jumper - no
external grounding strap required
• Tamper-proof internal jumper protected
from the environment
• Exceeds code requirements for long
conduit runs to permit linear movement

With a wrench, tighten the gland
nut to compress the Teflon packing, creating a rain-tight seal
around the conduit.

3
Thread the next length of conduit
into the other end of the fitting
and tighten. You’re done!

Sealing Fittings
Explosionproof, Dust-Ignitionproof
Application
EYD drain and inspection sealing fittings:
• Restrict the passage of gases, vapors or flames from one portion of
the electrical installation to another at atmospheric pressure and
normal ambient temperatures.
• Limit explosions to the sealed-off enclosure.
• Prevent precompression or “pressure piling” in conduit systems.
Drain sealing fittings are installed in vertical conduit runs and at low
points in conduit systems to prevent accumulation of condensate
above seal.
Features:
EYD drain sealing fittings include:
• Drain to provide continuous, automatic drainage of condensate.
• Large openings with threaded closures to provide easy access to
conduit hubs for making dams.
• Integral bushings to protect conductor insulation from damage.
• Tapered-tapped hubs to ensure ground continuity.
Standard Materials
• Bodies, and inspection or drain covers – Gray iron alloy and/or
ductile iron.
• Closure for drain – copper-free aluminum or ductile iron.
• Small closure plug – Gray iron alloy and/or steel.
• Drain – stainless steel.
• Removable nipples – steel.
Standard Finish
• Gray iron alloy and ductile iron – electrogalvanized and aluminum
acrylic paint.
• Copper-free aluminum – natural.

Application
The Thomas & Betts Universal drain/breather fittings can be used as drains
or breathers depending on the installation.
• To use as a drain, the product must be installed in the bottom of the enclosure or the lowest point where an NPT threaded opening exists. It can also
be used in a seal fitting or a “T” conduit body. These must be in a lower section of the conduit system. This will allow moisture inside the conduit system
to drain out.
• To use as a breather, installation should be done at the top of an enclosure
or in upper sections of conduit systems. This will permit air exchange and
keep moisture accumulation inside the conduit system to a minimum,
Thomas & Betts recommends the use of at least 2 devices (one drain and
one breather) for maximum efficency.

Preparation
Applications
Red•Dot® sealing cement is used for making seals in sealing fittings.
The insulation in the conductors sealed in the cement may be approved
thermoplastic or rubber, with or without lead covering. The sealing cement
should not be used for insulating.
Characteristics
Red•Dot® sealing cement is not affected by gasoline, alcohol, acetone,
ether, naptha, petroleum, benzol or lacquer solvent.

Sealing Cement

Packing Fiber

Preparation
(1) Use a clean mixing vessel for each batch.
(2) Thoroughly mix powder before adding water.
(3) Do not use if temperature is below 40°F.
(4) Mix 1 part water to 2 parts cement.
(5) Allow cement to set for 72 hours before use.
Standard Dams
(1) Push the conductors away from the filling opening and force them apart
so that they do not touch each other or the walls of the fitting or conduit
along their length. If the conductors do touch, the sealing cement will
not form a closed path between them.
(2) Force the packing fiber between each conductor and the inside walls.
Be sure that the dam is strong enough and tight enough to prevent the
considerable weight of the fluid sealing cement from seeping out.
Pouring
(1) Pour the mixed cement into the fitting slowly so as not to trap air in the
seal.
(2) Replace the close-up plugs to insure that they engage not less than 5
full threads.

The Copper Colloidal Surface Treatment That Protects,
Lubricates and Enhances Conductivity Between All Electrical
Connections

Kopr-Shield™ by Thomas & Betts meets the
requirements of Section 300.6(A) in the
2002 NEC Code for Protection Against
Corrosion.
“Where corrosion protection is
necessary and the conduit is
threaded in the field, the threads
shall be coated with an
approved electrically conductive,
corrosion-resistant compound.”

Good connections are one of the most important aspects of electrical work.
Mechanics know how much down-time is caused when fluids or oils leak into the
raceway system or looking for a weak link in a ground system caused by a high
resistance connection. Mechanics also know how much time is spent keeping contacts, switches, lugs and other connectors clean or replacing parts because of
“green scourge” build-up. Thomas & Betts has the solution to improve connections
made in thousands of electrical and raceway installations made each day by electricians everywhere.
Kopr-Shield™ compound is a unique homogenized blend of pure, polished colloidal
copper, rust and corrosion inhibitors that simultaneously protects, lubricates and
enhances the conductivity of the mating surfaces to which it is applied. Extremely
adhesive, Kopr-Shield™ compound flows smoothly into uneven contours and voids,
making application easy, protection and lubrication complete and positive. A stable compound, it will not settle-out, thin, thicken, harden, or dry out under the most
severe environmental conditions.
Kopr-Shield™ Compound has excellent temperature characteristics – brushed on at
–50F to 250F (other compounds either turn solid or run like water at these
extremes). Even at 1800F, Kopr-Shield™ remains intact for short terms.
Kopr-Shield™ Compound may be used to advantage in all electrical installations.
When the environment is hostile to good electrical and mechanical connections,
Kopr-Shield™ Compound is a must!
Use Kopr-Shield™ Compound for Battery Lugs and Cables.
• Prevention of “Green Scourge” corrosion.
• Reduction of resistance.
• Ease of terminal installation and removal.
Use Kopr-Shield™ Compound for Raceways.
• Lubrication – Ease of assembly and disassembly.
• Grounding Continuity Improved – Exceeds code requirements.
Use Kopr-Shield™ Compound for Fuse Clips.
• Even Heat Distribution – Elimination of hot spots.
• Oxidation Prevention – Prevents carbon path formation.
• Lubrication – Easy installation and removal of fuses.
Use Kopr-Shield™ Compound for Wiping Contacts, Drum Switches and Slip
Rings.
• Prevention of galling, burning, pitting and discoloration.
• Suppression of arching and dissipation of coronas.
• Lubrication for ease of operation.

Metal Clad Cable Termination Fittings
Metal Clad Cable Teck Cable Aluminum Sheathed Cable
Metal Clad Cable
(Type MC)
Ref. NEC Article 334*
“Metal Clad Cable Type MC is a factory
assembly of one or more conductors,
each individually insulated and enclosed
in a metallic sheath of interlocking tape,
or a smooth or corrugated tube.”
Metal Clad Cable Type MC is rated
for use up to 5,000 volts. The National
Electrical Code permits use of metallic
sheath as an equipment grounding
conductor.
Metal Clad Cables are available with
a variety of phase conductor insulations
such as crosslinked polyethylene, and
silicone rubber ethylene propylene,
depending on rated temperature of conductors and working potential. Metallic
sheath can be of galvanized steel, aluminum, copper or bronze. A special
outer covering such as PVC or
Neoprene over metallic sheath is usually provided for environmental protection.
Metal clad cable is not permitted in
locations where it could be subject to
physical damage. Metal clad cable
can be used exposed, concealed, in
cable tray, in any approved raceway,
and with minor exceptions in hazardous locations. Type MC cable can
also be used for services, feeders,
branch circuits, power, lighting, control
and signal circuits.
Use of metal clad cable is permitted
in wet locations, or where exposed to
destructive corrosive conditions or can

A98

be directly buried in earth, concrete or
exposed to cinder fills, strong chlorides, caustic alkalis, vapors, chlorine
or hydrochloric acids provided the
construction of cable, the conductors
within the metallic sheath, the metallic
sheath and protective cover over
metallic sheath comply with requirements enumerated in Sec. 334-3 of the
National Electrical Code.
Bend radius restrictions are dependent on the size of the cable and the
type of sheath, i.e. smooth, interlocked
armor, corrugated sheath or shielded
conductors and varies from 7 times to
15 times cable external diameter.
NEC Article 334 requires that
approved fittings be used for termination. Where single-conductor cables
carrying alternating current enter a ferrous metal box or enclosure, procedures described in NEC Section 30020 must be followed to reduce effects
of heating due to induced currents.
These procedures include recommended arrangements of conductors,
cutting of slots in metal between individual conductor holes, passing of
conductors through insulating walls, or
use of non-magnetic aluminum
sheathed cable and aluminum terminating fittings.

Metal Clad Cable Teck Cable Aluminum Sheathed Cable – continued
Teck Cables
Teck cable derived its name from one
of its first users, the Teck-Hughes Gold
Mines in Kirkland Lake, Ontario. Teck
90 is CSA Type designation. Trade designation of this cable is Armored Cable.
Teck cables up to 5,000 volt working
potential are manufactured in accordance with CSA Standard C22.2 No.
131 and are provided with a bare
ground conductor and an optional
outer jacket. Depending on phase conductor insulation the cables are designated as Teck 90 (X-LINK) when insulation is cross-linked polyethylene and
Teck 90 (EP) when insulation is ethylene propylene. Both cables are rated
for 90°C service (dry location) and
75°C (wet locations). When Teck cable
is suitable for installation down to
minus 40°F the cables are marked
Teck 90 (X-LINK) minus 40 or Teck 90
(EP) minus 40.
Over 5,000 volts working potential
Teck cables are manufactured in accordance with IPCEA standards and are
certified by CSA. Cables are provided
with or without ground wire as required.
Teck cables with outer jacket may
be used for exposed or concealed

wiring in wet or dry locations,
indoors/outdoors and in corrosive environments. Teck cables are suitable for
use in ventilated, non-ventilated and
ladder type cable troughs, in ventilated
flexible cable ways in both dry and wet
locations. Teck cable with outer jacket
is suitable for direct earth burial and for
Class II Division 2, Class III Division 1
& 2 hazardous locations per Canadian
Electric Code.
Some of the features of Teck cable
are its flexibility and ease of installation. Absence of dead air space within
cable increases heat transfer and minimize condensation. Overall protective
covering provides good environmental
protection.
Bend radii for permanent training
during installation usually varies
between 7 times to 12 times the cable
diameter depending on cable construction and manufacturer’s recommendations. Larger radii bends are
required for other conditions.
Section 12-3028 of the Canadian
Electric Code requires that the terminating fittings used must provide adequate strain relief to terminal connections and ensure electrical continuity
without injury to non-metallic sheath.

Continuity is mandatory whether or not
the armour is used as a grounding
conductor. Except for dry locations free
from corrosive atmosphere, the nonmetallic jacket is not permitted to be
stripped back to a point where armour
is exposed after installation.
Where single conductor cables carrying 200 amps or more enter metal
boxes through separate openings certain precautions are required to prevent overheating of the metal by induction. Use of non-ferrous or non-metallic
box connectors, locknuts and bushings and installation of non-magnetic
panel inserts is suggested in the code.

Electrical Metallic Tubing (EMT)
Ref. NEC Article 348
Electrical Metallic Tubing (EMT) is similar to rigid steel conduit but is much
lighter, weighing approximately 40 percent as much as rigid steel conduit of
the same nominal size. EMT can be
used for both exposed or concealed
work provided, where during installation or afterwards, it is not subjected to
severe physical damage. Use of EMT
is restricted to systems not exceeding
600 volts and to non-hazardous locations except (Class II Division 2 NEC
Section 502-4 (b).
Galvanized Steel EMT installed in
concrete on grade or above generally
requires no supplementary corrosion
protection. However, when installed in
concrete below grade level and in contact with soil or cinders supplementary
corrosion protection consisting of a
protective coating of bitumastic or
asphalt base paint or plastic is generally applied. According to NEC Section
348-1, EMT run in or under permanently moist cinder fill must be encased in
at least two inches of cinder free concrete unless the conduit is at least 18
inches below the fill.
Aluminum EMT cannot be directly
embedded in concrete containing soluble chlorides such as calcium chloride, unwashed beach sand, sea water
or coral bearing aggregates. When
adequately treated with a protective
coating of bitumastic or asphalt base
paint or plastic coating the raceway
can be installed in concrete containing
chlorides.
NEC Sections 384-4 and 300-6
require that in wet locations where
walls are frequently washed or where
there are surfaces of absorbent material the entire wiring system including
boxes, fittings, conduits and cables
must be supported such that there is at
least 1⁄4 inch air space between it and
the supporting surface.

Connectors and couplings are
required to be of concrete tight type
when embedded in masonry or concrete or in dry locations and of the rain
tight type when installed in wet locations (NEC Section 348-8).
According to NEC Section 373-6,
where No. 4 or larger underground
conductors enter or leave a conduit, an
insulating bushing with a smooth well
rounded insulating surface must be
provided to protect conductors, unless
the terminating fitting is equipped with
an insulated throat, firmly secured in
place providing equivalent protection.
The insulating bushing or insulating
material must have a temperature rating of not less than the insulation temperature rating of installed conductors.
NEC Section 300-10 requires that
the raceways be metallically joined
together into a continuous electric conductor and must be mechanically connected to all boxes, fittings and cabinets as to provide effective electrical
continuity.
EMT is not permitted to be threaded. Cut ends of tubing are required to
be reamed. Code requires that EMT be
adequately supported and restricts
bends in one run to the equivalent of
four quarters i.e. 360 degrees total.

Liquidtight Fittings for Special
Applications
The Revolver™ Externally Grounded
Fitting
The grounding lug of the new Revolver
connector can be rotated in a full circle
for convenient positioning that doesn’t
change when you tighten it. Plus, it’s
available for the first time in aluminum.
It’s a major breakthrough in convenience that saves time and money on
the job while delivering a quality connection.
Chase-Style Fittings
Where space is tight, our Chase fittings
allow for compact connections within
an enclosure.

Liquidtight Flexible Non-Metallic
Conduit Fittings
When non-metallic, Type A or EFC conduits are called for, Thomas & Betts’
XTRAFLEX System has our outstanding
Bullet fittings and conduits for liquidand dust-tight connections.
Bullet fittings:
• Feature one piece construction and a
captive o-ring for ease of installation.
• Provide a positive seal between the
conduit and the connector.
• Have a tapered thread hub and sealing o-ring for a tight seal to the box or
other enclosure.

PVC-Coated Connectors
When environmental conditions are
particularly harsh and corrosive, our
PVC-coated connectors are the best
choice for both indoor and outdoor
applications. The PVC coating protects
exposed surfaces for long-lasting, reliable connections.
Sealing Gaskets
Thomas & Betts sealing gaskets are
resistant to oil, coolants, and hydraulic
fluids as well as water, with a stainless
steel retaining clip that assures a quality seal. They’re the ideal match to our
Liquidtight connectors for a safe and
secure seal.

• Are constructed of non-burning, nondripping thermoplastic for high
strength chemical resistance.
• Feature a smooth insulated body for
maximum dielectric strength.
• Have a patented, serrated design
that provides high mechanical pullout
strength.
• Include a complete range of flexible,
non-metallic conduits – including both
smooth and corrugated varieties – to

XTRAFLEX® System – Conduit, Tubing, Fittings for Nonmetallic Liquidtight Conduit
The BULLET® nonmetallic liquidtight fitting –
easy to use, built to take it.

• Clamping fingers. Outside surface has friction
reducing ridges; inner surface teeth bite into
conduit or tubing to enhance clamping and
sealing action.
• Fitting ferrule is designed to accept variations
in conduit sizes and field conduit cuts.
• Ferrule profile is smooth, reducing friction to
assure a tight conduit-to-fitting seal.
• Friction reducing ridges and teeth provide a
true double seal and high pullout resistance.
• Elongated gland nut provides additional strain
relief for 90° pull and easy hand grip.
• Rugged low-profile nonmetallic body and
gland construction provides space savings.
• Captivated sealing “O” ring features predetermined compression to provide a reliable seal
at enclosure.
• Steel locknut firmly secures fitting to box or
enclosure.

This engineering breakthrough meets
the demand for a tough, reusable, nonmetallic liquidtight fitting for use with
XTRAFLEX® Type B conduit or flexible
tubing.
The BULLET® nonmetallic fitting provides a reliable liquidtight seal that
combines high pullout resistance and
ease of installation.
Engineered to meet your needs.
The BULLET® nonmetallic fitting meets
your performance requirements when
terminating Type B liquidtight nonmetallic conduit or flexible nonmetallic tubing
to a box or enclosure with knockout
opening or threaded hub. Fittings meet
the watertight requirements for NEMA
type 4 and type 6 enclosures and conform to UL514B, and CSA No. 22.2
#227.2 specifications.
Ease of installation.
Installations can be performed quickly
and easily because BULLET® liquidtight fittings can be installed without

disassembly. BULLET® nonmetallic fittings are resistant to numerous caustics and solvents.
And the BULLET® fitting is economical
because it can be used over and over
again without sacrificing the quality of
the original seal. When used with the
XTRAFLEX® raceway system you can
meet most machine or industrial
requirements where liquidtight protection is needed.
Corrosion resistant. Built to take it.
The BULLET® liquidtight fitting is manufactured from weather resistant thermoplastic materials, and is suitable for
indoor or outdoor corrosive environments.
The BULLET® fitting is resistant to
detergents, cleaners, oils, sanitizers,
paints, cutting fluids and wiring pulling
compounds–just about any liquid usually found in industrial, plant or marine
environments. It also surpasses industry standards for cold impact and simulated hammer blows.

When you have a conduit application in a liquidtight environment, it's time to load up
the T&B Bullet®. Thomas & Betts introduces the ISO Metric Bullet® liquidtight fittings for
use with the c", d", and f" Xtraflex® EFC and LTC nonmetallic
liquidtight conduit series.
The T&B Bullet® liquidtight fitting and EFC non-metallic
conduit are suited for OEM applications as in the
machine tool industry where environments include
continuous motion, vibration, and exposure to moisture, oil, dirt and dust.
The T&B Bullet® liquidtight fitting and LTC nonmetallic conduit are also suitable for construction
applications where ISO metric threading and liquidtight systems are installed.
The Xtraflex® system offers a lightweight, liquidtight
flexible conduit solution for industrial applications. The
Xtraflex® system allows fast, easy installation and high performance in demanding industrial applications.

Suggested Specifications for Flexible Cord and Cable Fittings

2920 Series

2920NM Series

2920AL Series

• Flexible cord or cable and associated fittings shall be suitable for conditions of use and location and
approved for the purpose by a
nationally recognized testing laboratory, inspection agency or product
evaluation organization.
• Flexible cord or cable shall be so
connected to the device or fitting that
tension will not be transmitted to
joints or terminal screws. Sufficient
slack shall be provided to avoid
sharp flexing and straining. Cord or
cable shall be installed in such a
manner that liquid will tend to run off
the surface instead of draining
towards the fitting.

• Where flexible cord or cable exposed
to intermittent or constant moisture
and subjected to mechanical strain is
terminated into a threaded or threadless opening, terminating fittings
shall be of watertight strain relief type
such as Thomas & Betts series 2920,
2920AL, 2920NM, 2520, 2631 or
2672. Fittings shall be equipped with
a beveled moisture resistant/oil resistant synthetic rubber bushing.
• Where space is limited inside the
enclosure, a female hub type fitting
such as Thomas & Betts series 2631
shall be furnished. A captivated
resilient sealing ‘O’ ring shall be
included to positively protect against
damage from overtorquing.

Note: Range of cord dia. ± .010.
In many applications you have only room for one fitting but you need to run two cables, for example, proximity switches. Now you can
provide strain relief and liquidtight protection with T&B’s new multi-hole liquidtight strain relief connectors. With the ever increasing
number of signal cables, now you have a solution to the problem of how to strain relieve multiple cables in one fitting.

Watertight Connectors for Oval Cable

A design with two tapers inside the body – a
slow one and a fast one – permits the stocking
of fewer connectors for varied cable sizes and
allows maximum take-up. The tapered neoprene bushings are resistant to oil, sunlight,
and water. Hex gland and body take the same
wrench opening and a stainless steel slip ring
prevents cable from twisting as gland ring is
being tightened. Threads on the body are
tapered for watersealing.

Armored Cable and Flexible Metal Conduit
Armored Cable (Type AC) – Ref. NEC
Article 333
National Electric Code defines type AC
armored cable as, “A fabricated
assembly of insulated conductors in a
flexible metallic enclosure.”
ACT
indicates an armored cable
employing conductors having
thermoplastic (Type T) insulation.
AC
indicates an armored cable
employing conductors having
rubber insulation of code
grade.
ACH
indicates an armored cable
employing conductors having
rubber insulation of the heat
resistant (75°C) grade.
ACHH indicates an armored cable
employing conductors having
rubber insulation of the heat
resistant (90°C) grade.
ACU
indicates an armored cable
employing conductors having
rubber insulation of latex grade.
‘L’
used as a suffix indicates
that a lead covering has
been applied over the conductor assembly.

All above cables may employ copper
or aluminum or copperclad aluminum
conductors with the following sizes and
are rated for 600 volts or less:
No. 14 AWG to No. 1 AWG Copper
No. 12 AWG to No. 1 AWG Aluminum
or Copperclad Aluminum
Type AC cables except ACL carry
an internal bonding strip of copper or
aluminum in intimate contact with the
armor for its entire length. Armored
cable can be used for both exposed or
concealed locations. With lead covered conductors (Type ACL) the cable
can be embedded in masonry or concrete and can be used in damp locations or where exposed to oil.
Armored cable is not permitted in
locations where it will be subjected to
physical damage or corrosive fumes.
Armored cable cannot be used for
direct burial in earth.
With minor exceptions armored
cable is also not permitted to be used
in hoists or elevators, storage battery
rooms, any hazardous locations, in
commercial garages and in theaters or
similar locations.
Codes require that cable shall be
supported with straps or staples without damaging conductors and also
limit the minimum bend radius to 5
times the diameter of type AC cable.
Certain precautions are prescribed in
code where cable is installed through
joist rafters or similar wood members.

Please Note
The excerpts and other material herein, whether relating
to the National Electrical Code, the Underwriters
Laboratories, Inc. listing, to industry practice or otherwise, is

According to NEC 333-9 where
armored cable is terminated, a fitting
is required to protect conductors from
abrasion. In addition a bushing is
required between the conductors and
armor. Design of fitting has to be such
that the insulating bushing is visible for
inspection. Bushing is not required
with lead covered cables when properly installed.

Armored Cable and Flexible Metal Conduit – continued
Flexible Metal Conduit – Ref. NEC Article 350
Flexible metal conduit can be used for
exposed or concealed work in dry
locations. It can be used for wet locations provided conductors within are
lead covered or other approved type.
Flexible metal conduit cannot be
used underground or embedded in
poured concrete or aggregate. With
rubber covered conductors the conduit
cannot be exposed to oil, gasoline or
other materials having a deteriorating
effect on rubber.
With minor exceptions use of flexible
metal conduit is not permitted in hoists,
in storage battery rooms and in any
hazardous locations. Use of flexible
metal conduit is restricted to systems
under 600 volts.
According to NEC Article 350-5, flexible metal conduit no longer than six feet
and containing circuit conductors protected by overcurrent device rated for
20 amps or less is suitable as a grounding means provided, it is terminated in
fittings approved for the purpose.

A162

Flexible metal conduit longer than
six feet is permitted to be used as a
grounding means provided the conduit
and the fitting are approved for the
purpose. To date there is no flexible
metal conduit approved for the purpose by the Underwriters Laboratories.
In Class I & II, Division 2 hazardous
areas, the conduit itself cannot be
used as the grounding means. A bonding jumper must be installed in accordance with NEC Section 250-79(e).
Flexible metal conduit is available with
steel or aluminum armor in trade size
j" to 4". With few exceptions where j"
and c" trade sizes are used, Code prohibits use of conduit less than d" trade
size. Bends in concealed work are
restricted to 360 degrees total. No
angle connectors are permitted in concealed raceway installations.

Armored Cable and Flexible Metal Conduit Fittings
Armored Cable & Flexible Metal Conduit Connectors

3110 Series

Application
• To connect and effectively bond
armored cable or flexible metal conduit to a box or an enclosure.
Features
• Provided with a saddle designed to:
(1) Firmly secure conduit in place
without damaging cable armor
(Mechanical holding power of
angled wedge assembly increases with increased strain.).
(2) Provide high quality bond
between conduit or cable and is
unaffected by vibrations.
(3) Centralize conduit or cable with
respect to throat opening for
conductors.
• Insulated throat protects conductors
during and after installation, reduces
wire pull effort and prevents thread
damage in handling.
• Locknuts designed to provide effective bond between connector and box
or enclosure, will not vibrate loose.
• Designed with fewer screws –
reduces installation time and cost.

Range
3110 Series Straight Connectors
3130 Series 90° Connectors

• Rugged all steel or malleable iron
construction.
• Suitable as a grounding means per
N.E.C. Article 350-5 (thru 3" trade

Steel or malleable iron.
Available with or without insulated throat, this
Tite-Bite® connector line is by far the easiest
and best to install when making sharp bends at
the enclosure or equipment. It has all of the
advantages of the straight connector with only
one screw to tighten, except in the larger sizes
where there are two. A peep hole on top provides for easy inspection of the ABC bushing.
Narrow design makes it easy to install connectors in adjacent knockouts.

Non-Metallic Sheathed Cable Fittings
Non-Metallic Sheathed Cable
Ref. NEC Article 336
Code defines Non-Metallic Sheathed
Cable as, “A factory assembly of two
or more insulated conductors having
an outer sheath of moisture resistant,
flame retardant, non-metallic material.”
Non-metallic sheathed cable is constructed of insulated conductors (14 to
2 AWG Copper or 12 to 2 AWG
Aluminum or Copperclad Aluminum),
and an outer non-metallic sheath classified as Type NM or Type NMC.
Non-metallic sheath cable is provided with or without a bare or insulated
equipment grounding conductor. Nonmetallic sheathed cable is rated for
60°C service with voltage limitation of
600 volts.
Type NM – has flame retardant
moisture resistant sheath.
Type NMC – has flame retardant
moisture resistant, fungus resistant –
and corrosion resistant sheath.
Non-metallic sheathed cable is permitted by code to be used exposed or
concealed in one, two or multifamily
dwellings or other structures not
exceeding three floors. Use of Type NM
cable is restricted to dry locations where
as Type NMC can be used in dry, moist,
damp or corrosive environments.

Non-metallic sheath cable (both
Type NM & NMC) is not permitted to
be used as a service conductor, in
commercial garages, in hoists or cannot be embedded in cement, concrete
or aggregate. With minor exceptions
use of non-metallic sheathed cable is
also prohibited in theaters or any hazardous locations.
NEC Section 336-5 requires that cable
be secured in place by suitable means
so as not to injure the cable. Adequate
protection for cable is also required when
run is exposed, through joists or rafters,
through floors, in unfinished basements
and accessible attics.
Cable bends are limited to a minimum
of five times the diameter of the cable.
NEC 300-4(b) requires that cable be
protected from physical damage when
it passes through factory or field
punched, cut or drilled holes in metal
members. A bushing or grommet firmly
secured in place is recommended.
