NEMA 3R Aluminum Shell: The alumnium shell reduces the overall weight of the unit compared to a steel shell.
Shell is powder coated.

2

Meter Socket & Test Switch on Swinging Door: Unit includes a 13-terminal CT-rated block. An 8-terminal block
option is also available. Includes a 10-pole test switch. A 7-pole test switch option is also available. Factory pre-wired
to conform to individual utility specifications.

3

Utility-Specific Wiring Harness: Wiring harness is color configured and wired per the utility specifications.

4

VT Pack Mounting Bridge: VT pack mounting bridge allows for installation of VT packs.

5

Wall Mount Bracket: Provides an easier means of installation for one installer, who can premount the bracket and
then hang the unit onto the wall bracket.

6

Stainless Steel Liftoff Handles: The durable, rust-resistant hinged handles lay flat against the front.

Utility requirements for this equipment may vary. Always consult the serving

Test Switches

TEST
SWITCHES

Details & Test Switch Covers

Switch Blades
Two dimples coined into one side of the
switch blade ensure positive contact in
corrosive, sooty environments—even
after years of inactivity.
Test Switch Covers
Standard test switch covers are made
from impact resistant clear thermal
plastic which has excellent tracking and
moisture resistant properties. If covers
are required, add suffix -WC (with cover)
to the catalog number or order separately
catalog number K3388. Black flush
mount covers are also available. Order
catalog number K3388-BLK-FL. 10 pole
base only.

Test Switch Base
The base is molded from a high strength,
fiberglass reinforced, thermoset
polyester. This material is track resistant,
flame retardant and has low water
absorption qualities. Bases are available
in 7 pole and 10 pole sizes.
Switch Jaws
The switch blade jaw clips are constructed
from spring grade copper alloy. The
material and design ensure excellent
contact which prevents overheating.

Polarity Barrier
For maximum protection potential
circuits are supplied with permanently
mounted barriers made from high tensile
strength polycarbonate.
Current Carrying Parts
Highly conductive copper and copper
alloy materials are used on all current
carrying parts. This ensures conductivity
and deters corrosion. Spring grades are
used where appropriate. Plating is
available if required. Contact general
offices to special order.

Nickel Plating Option
Corrosion-resistant test switches with
nickel plating are available as an option.

Standard Cover
Flush Mount Cover (Black)
Socket shells must be 51⁄8" deep
-ORmust not have test switch bridge
mounted on back
in order to support a cover.

Factory Installed: For cover installed add the suffix -WC or -WCFL to the catalog number of desired test switch.
Field Installed: For field installed cover order kit number K3388 or K3388-BLK-FL.
The Milbank test switch is designed to meet the critical requirements of the electric utility industry. Not only do
they meet EEI, ANSI C12.9, and UL standards but they combine several special features giving the Milbank test
switch increased safety, durability and reliability. One such feature is our unique switch blade contact points
which cut through residue that builds up after years of service. Another distinction is our polarity barrier which is
designed to be flexible as well as offer exceptional insulating qualities. Our test switches are constructed from the
latest materials available using modern fabricating and assembly methods.

Utility requirements for this equipment may vary. Always consult the serving
utility for their requirements before ordering or installing equipment.

Energization of Electrical Equipment

ENERGIZATION
OF ELECTRICAL
EQUIPMENT

Important Information for Installers

Important Note
In addition to national and local electrical codes, many utilities have specific requirements for metering equipment. Always consult the serving
utility for their specifications and requirements prior to ordering or installing Milbank meter mounting equipment.

Before Energizing
A. Give equipment a thorough visual examination to determine that:
		
1) No shipping or installation damage exists.
		
2) Proper clearances have been maintained.
		
3) All connections have been made.
		
4) Equipment is clean and dry.
B. Make a thorough examination to:
		
1) Verify tightness of all bolted connections (see table below).
		
2) Manually operate all circuit breakers, switches, relays, etc.
		
3) Check rigidity of all mountings, bus bars and components.
		
4) Use test equipment to check continuity of circuitry and integrity of insulation.
C. All switches and circuit breakers should be in the “off” position.
D. Verify that manual meter bypass (if applicable) is in non-bypass position.
E. Install cover and/or close doors.
F. If installation is not being energized at this time, follow “after-energizing” steps listed below. These steps will secure the installation in
	 case of accidental energization.

When Energizing
A. Use caution and follow established safety procedures:
	 1) Wear safety apparel.
	 2) Use safety equipment.
	 3) Take action to prevent injury to yourself and others in the event of failure of the installation.
	 4) Take action to prevent/decrease damage to property in the event of failure of the installation.
	 5) If you are unsure how to safely energize the installation, get someone who is knowledgeable to do it.

After Energizing
A. Secure the installation:
	 1) To prevent accidental contact with energized parts, cover all openings with approved filler devices.
	 2) To prevent unauthorized access, secure all covers and/or doors with approved security devices.
	 3) Attach/post information to advise others of potential hazards associated with the installation.

MATERIALS
& FINISHES

Materials
Steel Quality
The meter equipment listed in this catalog is made of galvanized steel (AISI* G90) to afford the best possible weather proofing.
*American Iron and Steel Institute.

Steel Sheet
16 gauge, galvanized, sheet: 1 1/4 oz./ sq.ft. class zinc-coated. (AISI G90)
14 gauge, galvanized, sheet: 1 1/4 oz./ sq.ft. class zinc-coated.

Aluminum Extrusion
Wire-Terminals: Alloy; 6061-T6, Tin-plated for CU/AL wire.
Bus Bar: Alloy; 6101-O & 6063-O

Aluminum Sheet
3000 series aluminum sheet, H14, or 5052 series aluminum sheet, H32. Where applicable thicknesses range from .064–.125

Copper Sheet & Bus
Electrolytic copper with tin plating in most applications.

Insulating Materials
• 	In most units, support bases for current-carrying components are molded from fiberglass reinforced high-strength, track resistant,
thermoset polyester molding compounds.
• 	Clear or black safety shields and polarity barriers are molded from high-strength, track resistant, polycarbonate molding compounds.
• 	Various sheet insulating materials, as appropriate for the application are utilized in the fabrication of flat, formed and punched component
parts and barriers.

Finish
Process
Light gray state-of-the-art electrostatically applied powder paint offers a durable, non-fading finish. For further information concerning the
chemical analysis of the weather resistant finish, please contact the factory.

Metal Fastners
Zinc-coated with a chromate dip.

Ratings & Compliance
Ratings & Compliance
All Milbank electrical enclosures in this catalog are rated “Type 3R Enclosure” unless specified otherwise on the product’s page. All
enclosures with a UL designation are constructed per the appropriate UL Standard and may be installed per the National Electric Code.
UL procedure files associated with the UL Standards are listed as follows: Meter Sockets (UL 414, File E30202), Test Switches (UL 414, File
E62531), Power Outlets (UL 231, File E90945), Panelboards (UL 67, File E32628) and Pullout Switches (UL 1429, File E133062). Additional
standards are utilized as applicable: Meter Sockets (ANSI C12.7), Test Switches (ANSI C12.9) and Panelboards (NEMA PB-1).
