Square D Load Center, Main Circuit Breaker, Convertible,150 Amps,208Y/120VAC, 240/120VAC Delta, 240VAC Delta

These Square D main lug load centers distribute power downstream from main breakers and are used when all the circuit slots in the main breaker load center are full or when a remote panel is desired. They can be converted to a main breaker load center, so they can be used to distribute the main supply of power if needed. These load centers have a neutral bar on either side of the bus bars, so compatible AFCI (arc fault circuit interrupter) or GFCI (ground fault circuit interrupter) breakers can plug directly onto the bus and neutral bars without requiring a pigtail connection. They're used with QO series circuit breakers to protect circuits from overcurrents. These load centers are used in residential, commercial, and industrial applications.
