 This information is based on use of 10,000 AIC rated 
branch circuit breakers in load center (MP-T, MH-T, 
MP-GT, MG). Most series ratings exclude MH-T 
above 40 Amp. Consult device wiring diagram for spe-
cific data.

Load centers on this page through 200 amp feature a new split neutral with 
one bonded and one insulated bar. For service entrance applications, install 
bonding strap, and use both bars for neutral and ground conductors. For non 
service entrance applications, do not install bonding strap and use insulated 
bar for neutral conductors and bonded bar for ground conductors.

, main breaker load centers are 
Underwriter’s Laboratories Listed 
for use with 60/75°C conductors and 
accept Murray branch circuit breakers 
which are also UL Listed for use 
with 60/75°C conductors. Type 3R 
load centers are furnished with a hub 
opening closure plate.
