Spectra Series®Power Panelboards

Features

2 Types of Power Panelboards Available

for Any Unique Application

Spectra Plug-In — Modular design utilizes plug-In modules

for circuit breakers and fusible switches.

Spectra Bolt-On — Circuit Breakers attached through bolted

copper connections

Spectra Series Power Panel Interiors

General Electric has designed plug-in and bolt-on style interiors

for use in all Spectra Series®Power Panelboard applications.

Spectra Plug-In interiors are designed for use with either

fusible switches or molded case circuit breakers or both.

Spectra Bolt-On interiors are designed for use with circuit

breakers only. Main or branch devices (fusible switch or circuit

breaker), as well as lugs only, can be installed in the factory

or at the construction site, providing for application flexibility.

Spectra Series Plug-In Interior

Double-insulated system consisting of bus support assemblies of

molded, glass-filled polyester insulation and heat shrink tubing

over high-strength steel bolts spaced on seven-inch centers

prevent bus bars from distorting during short-circuit conditions.

Standard bus is tin-plated aluminum, density rated at 750 amps

per square inch. Optional ratings include 1000A psi silver plated

copper and reduced density 600A psi aluminum or 800A psi copper.

Flexibility for Multiple Applications

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.

Spectra Bolt-On Power Panel

The Spectra Bolt-On Power Panel provides economical solu-

tions 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

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 align-

ment 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

250-1200A mechanical lugs are standard, copper compres-

sion 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.

Circuit breaker module

Circuit breaker modules feature integral spring reinforced

pressure locked connections and accept standard off-the-

shelf GE molded case circuit breakers for single- or double-

branch mounting.

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

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.

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.

Both module designs contain spring-reinforced pressure-

locked 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.

Spring-reinforced pressure-locked connectors

provide reliable connection to the panel bus.

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.

To prevent unauthorized personnel from accidentally releasing

the locked pressure connections, the handles are bolted to

each side of the module.

Fusible switch module

Fusible Switch Module Mounted on Interior

The fusible switch module has a self-aligning bracket

screwed to the interior mounting rails.

to 1200 amps. These neutrals have provisions for bonding and

grounding when required. The number of circuits has been

pre-engineered, depending on the amp rating. They can be

mounted in either corner of the enclosure in the same end

where the main device is installed. Each neutral is fully rated.

Equipment ground assembly

Isolated ground assembly

Isolated ground kit when required is field installed on either side

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

branches. Any distance between devices in different equip-

ment 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 selec-

tivity 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.

Table 1. Fuse Classification

Table 2. Maximum Horsepower①Fusible Switch

①Ratings are based on latest revision of the National Electrical Code Article 430.

Horsepower ratings for switches with Standard Class H fuses are based on one-time

fuses having minimum time-delay. When time-delay fuses are used, the horsepower

ratings are maximum for the switches.

Specifications Molded Case Circuit Breakers, WC-357B/GEN.

Fusible switches, W-S-865c.

• CSA Certified Distribution Panelboards.

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.

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.

•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:

Spectra Series®Power Panelboards

Application Data

For derating correction factors to be applied when the alti-

tude 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:

Table 27. Ambient Derating

For derating correction factors to be applied when the ambi-

ent exceeds the above, refer to the equipment application

bulletins or factory.

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.

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. Low-

voltage protective devices are fast operating and their short-

circuit 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

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:

Table 28

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 sym-

metrical 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.

Terminology

Ambient Temperature is the temperature of the surrounding

medium that comes in contact with a fuse or breaker.

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.

Amp Setting, Adjustable varies the continuous current-carrying

ability of a breaker through a predetermined range.

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-mean-

square) 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.

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.

Compression Lug, also called a crimp lug, is a lug that is

crimped to hold cable.

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

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 3-

pole breakers and fusible switches.

Enclosure is a constructed case to protect personnel against

contact with the enclosed equipment and to protect the

enclosed equipment against environmental conditions.

Equipment Grounding is the interconnection and grounding

of electrical material that either encloses or is adjacent to

power conducting components. (NEC 250-91(b))

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.

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.

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.

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.

I2tis the measure of heat energy developed within a circuit, in

which I2stands 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 spring-

reinforced to provide a highly reliable electrical connection.

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 panel-

board is accessible from the front only.

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.

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.

Rotor Mechanism in fusible switch unit that mechanically

ensures all switch blades open/close simultaneously.

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.

Series-Connected Rated Panel means the UL Listed short-

circuit rating of the panel is equal to the IC rating of the

main protective device when properly applied with its

branch circuit protective devices.

Service Disconnect is a device or group of devices that dis-

connects all ungrounded conductors.

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 inter-

rupting 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.

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.

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.

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.

Voltage Rating is the rms alternating current voltage at

which a fuse or circuit breaker is designed to operate.

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.

A four-piece front shall be furnished as standard to provide

ease of access to the wiring gutter.

When specified on the drawings, a front with a single door

shall be provided for panel boxes less than 31" wide. For

panel boxes 31" wide or wider, door-in-door type fronts shall

be provided when fronts are indicated on the drawings.

Door-in-door construction shall consist of a one-piece front

with two lockable doors. The smaller door shall provide

access to protective device handles and the larger door shall

allow access to device load terminals and the wiring gutter.

When fronts with doors are specified, all doors shall be provided

with locks. All doors shall be held in place by continuous piano

hinges which are welded to the front.

All fronts shall be mounted to the box with zinc-coated

screw fasteners to retard corrosion.

Main and Branch Devices

Main and branch-fusible switches shall be of the positive,

quick-make, quick-break type with double-break, over-center

mechanism. The external handle shall be suitable for pad-

locking in the “OFF” position and is interlocked with the switch

cover to prevent access to the switch interior when the switch

is in the “ON” position - an interlock override release is

provided. Fusible switch units shall be fully interchangeable

without disturbing the adjacent units and shall be capable of

withstanding the available let-through short-circuit current

as shown on the plans.

Main and branch circuit breakers shall be quick-make, quick-

break, and trip-indicating. All two and three pole breakers

shall have interchangeable trips. Interrupting rating of the

circuit breaker shall not be less than the maximum short-

circuit currents available at the incoming line terminals as

shown on the plans.

Interiors

Panelboard symmetrical interior shall be designed and

assembled so that the circuit-protective modules (either

fused switches less than 800A or circuit breakers) are mounted

onto the bus bar with self-aligning spring reinforced pressure-

locked connectors. The circuit-protective module can be

removed or replaced without disturbing adjacent protective

devices and without removing the main bus or branch circuit

connections. The interiors shall be capable of supporting

compatible fusible switches and molded case circuit breakers

in the same panelboard. Insulation barriers are installed over

vertical bus to provide protection when field service is

required for changes.

Bus Bars

Bus bars shall be current density rated and meet UL67

temperature rise limits through actual tests. Bus bar current

density rating shall be 750 amps per square inch for aluminum

or 1000 amps per square inch for copper as required by the

contract documents. Reduced current density bus shall have

ratings of 600 amps per square inch for aluminum or 800

amps per square inch for copper are also available.

Bus bars shall be sequenced-phased, and rigidly supported

by high-impact resistant, insulated bus supporting assemblies

to prevent vibration and resulting damage when subjected

to stress, vibration or short circuits. All solderless terminations

shall be suitable for either copper or aluminum UL Listed

wire or cable and shall be tested and listed in conjunction

with appropriate UL standards.

Panelboards shall be so designed to permit the incoming line

conductors to enter either the top or bottom of the enclosure.

The neutral bar shall be fully rated and capable of being

relocated to either corner of the enclosure at the line end to

facilitate conductor termination.

Ground wire terminations shall be provided as an option in

kit form suitable for installation by the panelboard installer

without voiding UL label.

Series Ratings

All panelboard series-connected ratings shall be prominently

displayed, and all current ratings of protective devices shall

be displayed on the device label.
