Features
Flexibility for Multiple Applications

Spectra Bolt-On Power Panel
The Spectra Bolt-On Power Panel provides economical solutions for your application needs. The design features main
lugs or main and branch circuit breakers bolted to the bus
bars. The factory-installed main lugs are bolted directly to the
bus bars; circuit breakers are bolted with mounting straps.
The Spectra Bolt-On power panelboard is rated for 100,000
AIC. Fusible switches are not available in the bolt-on design.
Main lug assembly

Spectra Bolt-On Power Panel:
• Circuit Breakers attached through bolted copper connections
• TVSS Unit
• Main Lugs
• Metering Modules
Spectra Plug-In Power Panel:
• Circuit Breaker Modules
• Fusible Switch Modules
• Intermix of Circuit Breaker and Fusible Switch Modules
• TVSS Unit
• PCU Modules
• Main Lug Modules
• Metering Modules
Each interior is fully rated; therefore large
amperage devices can be installed at
either the top or bottom of the interior.
The vertical design of the bus maximizes
convective heat transfer. The bus bar
insulator system provides short-circuit
protection, 600-volt spacing (without
having to add baffles). There is no need
for any additional insulation.
GE Tranquell TVSS (Transient Voltage Surge Suppressor)
provides outstanding protection from internally and externally
generated transients.

Aluminum mechanical lugs are standard, copper and
compression lugs are optional. The lugs are rated from 250
to 1200 amps, and offer front accessible set screws.
Circuit breaker assembly

Circuit breakers are bolted to the bus bars with copper
mounting straps utilizing anti-turn clips that simplify alignment when field-installing breakers. The mounting straps are
sized according to the breaker frame, not the trip amperage,
and are rated for 100,000 AIC.

Spectra Series® Power Panelboards

Features
Spectra Plug-In Power Panel
Spectra Plug-In offers modular flexibility featuring integral
spring reinforced pressure locked module connections.
Rated for 200,000 AIC, Spectra Plug-In panelboards feature
main lugs or main circuit breakers. Branch and other devices
available include molded case circuit breakers, fusible
switches, TVSS units and PCUs
Factory-installed MLO

Double branch PCU

The Spectra Series Process Control Unit (PCU) provides reliable
motor control technology in applications where space and
maintenance considerations are critical. Available from 1/4
to 15 hp. PCUs are available in Plug-In panels only.
Fusible switch modules

250-1200A mechanical lugs are standard, copper compression lugs are optional. Factory-installed lugs are bolted to
the bus bars, and offer front accessible set screws. Lug kits
also available for feed-thru applications.
Main lug module
Main lug modules include mechanical or compression lugs.
Main lug modules are available for field installation only.

Fusible switch modules from 30-1200 amps are available for
Plug-In panels only.
Field Changes Are Quick and Easy
This feature is possible because the interior is designed to
accept the spring-reinforced pressure-locked connectors.
The connectors are an integral part of the main and branch
modules.

Circuit breaker module

Circuit breaker modules feature integral spring reinforced
pressure locked connections and accept standard off-theshelf GE molded case circuit breakers for single- or doublebranch mounting.

After de-energizing the panel, a molded case circuit breaker or
a fusible module can be quickly removed from the panel. The
panel can be re-energized (after filling the space with proper
filler plate) while the module and its devices are maintained.
Combining modular assembly and pressure locked connections
to the interior, maintenance and testing are easier and faster.
• Main lug panels can be converted to a main breaker panel
easily.
• Branch fusible units can be removed and circuit breaker
units substituted quickly.

Spectra Series® Power Panelboards

Features
Module Features
Fusible switch and circuit breaker modules each consist of
two assemblies: the protective device (fusible switch unit or
molded case circuit breaker) and a connecting mechanism.
The connecting mechanisms are the intermediate electrical/
mechanical connections between the protective device and
the bus structure in the interior. There are two distinct designs.
The fusible connecting mechanism is in the same housing
as the fusible switch unit. The molded case circuit breaker
connecting mechanism is separate from the breakers and is
designed to accept standard GE circuit breakers. Both designs
are UL listed and CSA certified.

Plug-in circuit breaker module

Circuit Breaker Module Mounted on Interior

The circuit breaker module has a positive, self-aligning,
spring-loaded locking device bolted to each side of the
mounting module. This mechanism springs in to place, and
the locking latches are thus positively engaged in the interior
mounting rails.

Both module designs contain spring-reinforced pressurelocked connectors for engaging the bus bars. The connectors
are bolted to copper bars within the mechanism. The fusible
switch unit (or the breaker) is, in turn, bolted to these bars.
Modules are rated for 200,000 AIC.

To prevent unauthorized personnel from accidentally releasing
the locked pressure connections, the handles are bolted to
each side of the module.

Fusible switch module

Spring-reinforced pressure-locked connectors
provide reliable connection to the panel bus.

Fusible Switch Module Mounted on Interior

The fusible switch module has a self-aligning bracket
screwed to the interior mounting rails.

Series-Connected Ratings
UL permits assigning a short circuit rating to a combination of
molded case circuit breakers or fuses and molded case circuit
breakers connected in series that is higher than the lowest
rated protective device of the combination. This is defined as
series connected ratings. The combination rating cannot
exceed the rating of the protective device furthest upstream,
although it will exceed the rating of the downstream protector.
The upstream protector can be a molded case breaker or
fuse. Device combinations are not limited to those in the same
equipment. They can be in different equipments such as a
switchboard feeder or a panelboard main versus panelboard

Spectra Series® Power Panelboards

Electrical Data
branches. Any distance between devices in different equipment is permitted. Total fault current magnitude must flow
through both protectors. Thus, fault current contribution
from motors, as well as power source fault current, must
flow through upstream and downstream protectors.
It appears NEMA’s position will allow motor full load currents
not exceeding 1% of the downstream device interrupting rating
to be ignored.
Molded case circuit breakers may be applied as fully rated or
series rated. In a fully rated system, the short circuit ratings
of all protective devices are equal to, or exceed, the available
short circuit current. If mounted in equipment, the bus short
circuit withstand rating and equipment short circuit rating
must equal or exceed the available short circuit current.
In a series connected system, the short circuit rating of the
upstream protector is fully rated but the downstream protector
is not fully rated.
Selectivity between overcurrent devices is always desirable
but, in some cases, it difficult to achieve without over-sizing
devices or using Low Voltage Power Circuit Breakers in
switchgear. However, the National Electrical Code requires
complete selectivity in some types of circuits. As of the 2008
NEC, these include Elevator Control Circuits (article 620.62),
Emergency Systems (Article 700.27), Legally Required
Standby Systems (Article 701.18) and Critical Operations
Power Systems (Article 708.54).
Complete selectivity is usually interpreted as meaning selectivity for ground faults and all magnitude of phase faults up
to maximum theoretical bolted fault current level. Some
jurisdictions enforce the pertinent articles of the code only as
far as short time and long time selectivity, usually using the
0.1-second rule. Other jurisdictions enforce the requirement
for complete selectivity. It is advisable that the local
Jurisdiction Having Authority (JHA) be consulted to understand
the interpretation of the pertinent code articles for the
application being considered.
Full selectivity may be achieved in various ways. Traditionally, it
is achieved by ensuring that the instantaneous characteristic
of circuit breakers in series does not overlap up to available
fault current at the load side device. However, it is now
possible to achieve instantaneous selectivity of molded case
circuit breakers even when their instantaneous time curves
overlap. The selectivity available varies significantly by circuit
breaker model and size. To see available selectivity with GE
circuit breakers, please use GE publication DET-537. Before
selecting circuit breakers for a panel or switchboard in circuits
or applications that may be regulated by the aforementioned
code articles, it is advisable that the interpretation enforced
by the local JHA be understood and that circuit breaker
selection be undertaken with a full understanding on how to
achieve the selectivity required.

Refer to GE publication DET-008A (in the latest edition) for
complete series rating listings.

Interrupting Ratings
Panelboards have integrated short-circuit ratings. When
fully rated, the rating is that of the lowest-rated device in the
panelboard. When series-connected rated, the rating is that
of the main and branch-tested/UL Listed combination.
Short-Circuit Ratings - Fusible Switch Units
The short-circuit or interrupting rating of the fusible switch is
the lower of the fuse or the switch rating. Spectra Series
switches have a 200,000 amp short-circuit rating.

Note: Only panelboards containing all UL Listed devices can
be UL labeled.
In addition to meeting or exceeding all applicable standards
shown above, Spectra Series Power Panels meet GE’s more
stringent internal requirements, offering a greater margin of
performance and protection.
The following classifications and limitations of panelboards
have been established by the Underwriters’ Laboratories
and the National Electrical Code.
Note: An overcurrent protective device is a circuit breaker
pole or single fuse.

• When two or more separate panelboards are used, subfeed
lugs or thru-feed lugs (of same capacity as incoming mains)
must be included in all sections except the last one. Cables
or bus bars for interconnection are not included.
Power (or Distribution) Panelboards as per NEC 2005
There is no limitation as to the number and rating of branch
circuits, except as determined by available enclosures.
Note: NEC 2008 no longer distinguishes lighting and
appliance panelboards from distribution panelboards.

Service Entrance Equipment
• Must be located near the point of entrance of building
supply conductors.
• Lighting and appliance panels must have one, but not
more than two, main disconnections with a current rating
equal to or less than panelboard rating.
• Power panelboards may have up to six operating handles
to entirely disconnect panelboard from the source.
• Main disconnect must include ground fault protection if it
provides more than 150 volts to ground, and a maximum
current rating of 1,000 amps or more.
• Must include connector for bonding and grounding neutral
conductor.
• A service entrance-type UL label must be factory-installed
and will be provided on the equipment (when specified).
Service Conditions Equipment is rated for operation under
the following usual service conditions, unless limited by the
devices contained in the equipment. Unusual service
conditions should be referred to the factory. These included
requirements such as seismic, corrosive or explosive
atmospheres, vibration, shock and unusual operating duties,
and temperature.
Altitudes Equipment is rated for use up to a certain altitude.
Above these altitude values, which vary dependent on the
type of equipment being considered, the continuous current
and voltage rating may require modification to account for
increased temperature and lower dielectric strength.
Standard ratings may be applied up to the following altitudes:
Table 26. Altitude Derating
Equipment

Lighting Panelboards as per NEC 2005
• More than 10 percent of panelboard circuits are rated 30
amps or less, for which neutral connections are provided.
• Maximum 42 overcurrent protective devices per panel
(including subfeeds but not main overcurrent protective
devices). If more than 42 are required, two or more separate
panelboards must be used. Example: A two-pole device is
considered as two overcurrent devices.

Application Data
For derating correction factors to be applied when the altitude exceeds the above, refer to the equipment application
bulletins or factory.
Ambient Temperature Equipment is rated for use in a given
ambient, and if exceeded, the continuous current rating
requires derating. Rating correction is required if applied in
an ambient exceeding the following:

Current. The continuous current carried by a protective
device should not exceed 80% of the device rating unless
the equipment or assembly, including the protective device,
is listed for continuous operation at 100% of its rating. A
continuous load current is one that continues for three
hours or more. A noncontinuous load current may be 100%
of the device rating.
Low-voltage fusible switches are standard-rated 80% except
high pressure contact and bolted pressure switches, which
are 100% rated. Molded case circuit breakers equipped with
thermal magnetic trips are standard-rated (80%). When
equipped with electronic trips, they can be standard (80%)
or 100% rated.

symmetrical rms amps, but tested at known X/R ratios to
assure capability of interrupting the total fault current
asymmetrical fault. The X/R ratios at which they are tested
are as follows:

Thus, the low-voltage protective device interrupting rating
symmetrical rms must be equal to, or greater than, the circuit
symmetrical rms fault current and test X/R equal to, or
greater than, circuit X/R at point of application. If the circuit
asymmetrical current should be greater than the protective
device will withstand, then the protective devices interrupting
rating must be derated. Derating factors are identified in the
applicable application bulletins and standards.
Medium-and high-voltage fuses are rated in terms of symmetrical current, but can withstand the total asymmetrical
current provided the X/R ratio does not exceed 15. If the circuit
where applied exceeds an X/R of 15, then it is necessary to
derate the symmetrical current rating in accordance with
the applicable standard. Proper application of medium- and
high-voltage breakers requires that the circuit-short-circuit
duties during the first cycle (momentary), and at contact
parting time (interrupting), be compared with the circuit
breaker’s short-circuit capability to close and latch during
the first cycle, and to interrupt at some time later. Refer to
GET 3550 to determine methods of calculating short-circuit
currents for proper application.

When mounted in equipment, MCCB and fusible switches in
group-mounted configuration are all standard (80%) rated. In
individual mounted configuration, MCCB with electronic trip
can be standard (80%) or 100% rated. Insulated case circuit
breakers are standard (80%) or 100% rated. Low-voltage
power circuit breakers, type AKR, medium-voltage fuses, and
medium-voltage breaker PowerVac are all 100% rated. Lowvoltage protective devices are fast operating and their shortcircuit rating is based on the maximum current during the
first half cycle of fault current flow. The total fault current at
initiation of fault consists of two components: the ac and dc
components. The ac component is defined as the symmetrical
rms current, and ac plus dc, the asymmetrical rms current.
The magnitude and rate of decay of the dc component is a
function of the reactance to the resistance (X/R) ratio.
Low-voltage protective devices are rated on the basis of

Terminology
Ambient Temperature is the temperature of the surrounding
medium that comes in contact with a fuse or breaker.

and amps. Type of service determines the number of poles on
the main device, the numbers of poles valid for feeder or
branch devices, and the minimum voltages for 1-, 2-, or 3pole breakers and fusible switches.

Ampacity is the amount of current a fuse will carry continuously
without deterioration, or a circuit breaker without tripping and
without exceeding temperature rise limits specified for a particular
fuse or circuit breaker by NEC requirements and UL standards.

Enclosure is a constructed case to protect personnel against
contact with the enclosed equipment and to protect the
enclosed equipment against environmental conditions.

Amp Setting, Adjustable varies the continuous current-carrying
ability of a breaker through a predetermined range.

Equipment Grounding is the interconnection and grounding
of electrical material that either encloses or is adjacent to
power conducting components. (NEC 250-91(b))

Arcing Fault is a high-impedance connection, such as an arc
through air or across insulation, between two conductors.
Arcing Time, in a fuse, is the amount of time that elapses
between the melting of the current-responsive element, such
as a link, to the final circuit interruption. Arcing time is
dependent upon such factors as circuit voltage and impedance.
Available Short-Circuit Current is the maximum rms (root-meansquare) symmetrical current at a given point in a power system.
Branch Circuit is the circuit conductor between the final
overcurrent device protection and the outlets or point of use.

Expansion Kit An assembled kit that can be installed in an
empty side of a double-branch fusible switch unit to create a
new fusible switch unit. It includes the handle, base plate,
cover plate, load base and switch.
Feeder Circuit is all circuit conductors between the service
equipment or the source of a separately derived system and
the final branch-circuit overcurrent device.
Filler Mounts on side of fusible switch module, circuit breaker
module, or between side trims to cover the front of the enclosure.
The fillers plus trim comprise the enclosure front around the
installed devices.

Bus Bar is a solid aluminum or copper alloy bar that carries
current to the branch or feeder devices in a power panelboard
or switchboard. There is a least one bus bar for each phase of
the incoming electrical service.

Frame Size is a specific size of breaker with a specific range
of amp ratings. For example, an F-frame breaker is available
in ratings of 70 amps to 225 amps in a 225 amp frame.

Compression Lug, also called a crimp lug, is a lug that is
crimped to hold cable.

Front is the part of the panelboard that protects the interior
of the panelboard from environmental elements and prevents
accidental contact with the panel’s interior live conductors.

Continuous Load is when the maximum current is expected
to continue for three hours or more. (NEC Article 100)
Current Density is the amount of current traveling through a
member (cable, bus bar, etc.). It is a cross-section measurement
of the member in amps per square inch.
Current Sensors monitor and measure line-to-load and
return line-to-line current. An imbalance causes a relay to
signal the breaker to trip at a preset time and current level if
ground fault function is present.
Dead Front construction is where energized parts are not
exposed to a person on the operating side of the equipment.
Double-Branch A mounting module that contains two fusible
switch units or circuit breakers installed side by side.
Electrical Service or System is the conductors and equipment
which delivers energy from the electrical supply system to the
wiring system of the premises served. The service or system
consists of the number of phases, number of wires, voltages
26

Fuseholder or Fuse Block is an assembly of fuse clips and
insulation for mounting and connecting a fuse into the circuit.
Fusible Switch is a device that can switch off current flow
and to which a fuse(s) is added to protect conductors.
I2t is the measure of heat energy developed within a circuit, in
which I2 stands for effective let-through current squared, and
t is time in seconds.
Interior The side rails, bus bars and insulation system that
mounts in the enclosure. It is energized through the main device
(lugs, fusible switch or circuit breaker) and in turn energizes the
installed circuit protective devices (fusible switch or circuit breaker).
Interrupting Rating is the highest rms-rated current a fuse
or breaker is intended to interrupt under specified conditions.
Jaw Metal parts that grip the interior bus bar and conduct
electricity to the module bus bars. The jaws are springreinforced to provide a highly reliable electrical connection.

Spectra Series® Power Panelboards

Appendices
Line refers to the incoming (live) side of equipment or device.
Load is the outgoing (switched) side of equipment or device.
Lug is a device to terminate cables.
Magnetic Trip is synonymous with instantaneous trip and
describes a tripping acting with no intentional time delay.
Current exceeding the magnetic trip level will actuate the
trip mechanism and open the breaker contacts immediately.
Main Device is a fusible switch or circuit breaker that can
isolate the panelboard from incoming power.
Main Lug is the connecting means between the incoming
service cable and the bus bar.
Mechanical Lug is a terminal with one or more wire binding
screws that are tightened to hold the conductor or cable.
Overcurrent is any current in excess of the rated current of
equipment or the ampacity of a conductor that can result
from an overload, a short circuit or a ground fault.
Pole The number of output terminals on a fusible switch or
breaker that must be insulated and separated from each other.
Power Panelboard is any panelboard that is not a lighting or
appliance panelboard as specified by UL and NEC and is not
limited as to the number and rating of branch circuits, except
for available spacing and physical size. The dead-front panelboard is accessible from the front only.

Service Entrance Equipment, such as power panelboard,
consists of a fusible switch or breaker located near the point
of entrance of supply conductors to a building and serves as
the main control and disconnect of electrical power. Service
entrance equipment must include a connector for bonding
and grounding the neutral conductor at the entrance point of
the supply conductors and bear a UL service entrance label.
Shunt Trip opens a fusible switch breaker by remote control.
Single-Branch A mounting module that is sized to accept
one fusible switch unit or circuit breaker. A single-branch
fusible switch module may have one fusible switch unit
factory-installed on one side, and the other side specified
empty (blank) to facilitate installing future expansion kits.
Thermal Trip protects against sustained overloads. A
bimetallic element reacts time-wise in inverse proportion to
the current. If a circuit is overloaded, heat from excessive
current flow causes the bimetal to bend, actuating the trip
mechanism to open the breaker.
Time Delay is a term used by NEMA, ANSI and UL to denote a
minimum opening time of 10 seconds on an overload current
five times the amp rating of a circuit breaker or Class H, K, J
and R fuses. Time delay is useful to let through momentary
current inrushes, such as in motor startups, without interrupting the circuit.
Trim The four pieces of painted steel (top, bottom and each
side) that cover the front of the enclosure. The trim plus
fillers comprise the enclosure front.

Quick-make, Quick-break The action of a mechanism where
the speed of the contacts in opening and closing a breaker
or fusible switch is not controlled by the operator.

Trip Function is that portion of the breaker that senses fault
conditions, controls the associated logic functions and initiates
and powers the breaker trip device.

Rejection Fuse and Clip is a combination of Class R fuses
and clips that will not accept fuses with a lower short-circuit
rating. This type of fuse and clip has a mechanism that
rejects standard NEMA Class H fuses.

Trip Mechanisms are independent of manual control handles.
The breaker will trip when a fault occurs, even if the handle
is held in the “ON” position.

Rotor Mechanism in fusible switch unit that mechanically
ensures all switch blades open/close simultaneously.

Undervoltage release instantaneously trips the breaker when
voltage (control or line) drops to 30%-70% of nominal rating.
Voltage is electrical pressure that moves electrons through
a conductor and is measured in volts.

Selective Tripping is the application of circuit breakers or
fuses in series, so that, of the breakers or fuses carrying fault
current, only the one nearest the fault opens and isolates
the faulted circuit from the system.

Voltage Rating is the rms alternating current voltage at
which a fuse or circuit breaker is designed to operate.

Series-Connected Rated Panel means the UL Listed shortcircuit rating of the panel is equal to the IC rating of the
main protective device when properly applied with its
branch circuit protective devices.

X Value is a vertical measurement of the usable mounting
space on a panelboard for a fusible switch or breaker. X is
equal to 1 3/8 inches (1.375”). Height of the interior is the
sum of the horizontally mounted, panel-mounted components.

Service Disconnect is a device or group of devices that disconnects all ungrounded conductors.
