Siemens P1A42MC250C Load Center Panel 250 Amp 42 Space

Product Description

The SIEMENS P1A42MC250C is a main breaker load center designed for residential and light commercial electrical distribution. This panel provides a centralized point for circuit protection and power distribution, housing a factory-installed main breaker alongside branch circuit breaker positions. Rated at 250 amps with 42 available spaces, it gives electricians ample capacity for whole-home or small commercial service installations. The unit is built to meet standard load center mounting and wiring requirements and is installed by licensed electricians working under NEC guidelines.

This load center is suited for new construction and service upgrade applications where a main breaker panel with generous circuit capacity is required. The 42-space configuration supports a full complement of single-pole and double-pole branch breakers, making it appropriate for residential services with high circuit counts or light commercial panels requiring organized, code-compliant distribution. It ships as a complete assembly with the main breaker factory-installed.
