LOAD CENTERSGENERAL DESCRIPTION
MurrayLoad Centers—the industry standard of
highestquality...designed to complement theMurray line of Circuit
Breakers.
Load centers are used for the protection anddistribution of
loads in residential, commercialand light industrial applications
operating at 240volts AC max. Load centers subdivide powerinto
branch circuits serving a variety of smallloads. They provide a
switching and protectivefunction for these load circuits. Typical
loadsare lighting, appliance, heating and small motorbranch
circuits.
Murray load centers feature a new split neutraldesign in all
single phase main lug and mainbreaker models from 100 Amp, 12
circuitthrough 225 Amp, 42 circuit. These neutralshave one
insulated and one uninsulated neutralbar. For service entrance
applications, use bothbars for neutral and ground conductors.For
non-service entrance applications, useinsulated bar for neutral
conductors anduninsulated bar for ground conductors.
Load centers are often referred to as servicepanels, circuit
breaker panels, or several othernames, however, they are officially
knownas panelboards.
Design/Performance Features• New insulated and bonded split
neutral for
faster neater wiring.
Two neutral bars, one bonded, one insulated,connected with a
cross strap and removablebonding strap, allowing maximum
versatility.For service entrance applications, connect thebonding
strap and wire neutral and grounds toboth bars. For non-service
entranceapplications, disconnect the bonding strapand use insulated
bar for neutral and bondedbar for grounds. No need to
purchaseaccessory ground bars.
Neutral bars provide two sizes of terminalsfor maximum wire
range usage.
• One-piece bus bar construction, through 200amps, eliminates
heat producing joints andprovides cooler operation with longer
life.Alstan® 88 plating with a copper strikeensures maximum
electrical conductivity andcorrosion prevention.
• Circuit breaker landing pads provide branchcircuit breakers
positive fit and alignment.
• 100 through 225 amp load centers are offeredwith combination
surface/flush covers forgreater inventory flexibility
substantiallyreducing inventory space and investment.
Covers are attractively styled one-piece trimand dead front
design featuring an easy toopen and close sliding latch.
• NEMA 3R enclosures are constructed of G90galvanized steel
painted with anelectrodeposition process providing uniformcoverage
for maximum protection againstcorrosive environments and an
attactiveappearance.
• Bus protectors to guard against contaminationduring
installation and finish constructionwork.
• Drywall gauge visibly embossed on fourcorners of enclosure to
facilitate proper flushmounting.

®This information is based on use of 10,000 AIC ratedbranch
circuit breakers in load center (MP-T, MH T, MP-GT, MG). Most
series ratings exclude MH-T above 40Amp. Consult device wiring
diagram for specific data.
'1;Types MQH & MQL may be mounted internal in 150-225amp 30
main breaker load centers, and in 225 amp 10main breaker load
centers.
Series RatingsSeries ratings allow two or three breakers tobe
connected in series, such that the 2nd and3rd breakers have an
interrupting capacity lessthan the system available fault current.
Suchcombinations must be tested, and onlybreakers of the type and
ampere rating testedmay be used in this combination. Typicalusage
of series ratings would be main andbranch circuit breakers in load
centers. Themain breaker must have an interruptingcapacity at least
equal to the available faultcurrent. However, the branch breaker
mayhave an interrupting capacity lower than theavailable fault
current, provided the pair havebeen tested together as a
series-rated pair.

Industry and GovernmentSpecificationsMurray load centers meet or
exceed the latestedition of the following industry standardsand
Government specifications, unlessnoted otherwise:
IndustryNEMA—Standard #PB1
UL—Standards #50 and #67
US GovernmentStandard # WP-115b, Type 1, Class 2 coversload
centers through 200 Amps.
Spaces Versus PolesThe number of "spaces" available in a
loadcenter is the maximum number of 1" singlepole circuit breakers
that can be installed inthat load center. Because most load
centerswill accept half-size breakers, the actualnumber of single
pole breakers that may beinstalled is often more than the number of
1"spaces provided. In compliance with therequirements of the
National Electrical Code,a physical means is provided to prevent
theinstallation of more circiut breakers than thenumber of breakers
for which the load centerwas designed. This means of circuit
limitingallows the load centers to be UL Listed as"Class CTL".
