Siemens LC1224L1125 Main Lug Load Center 125A 12 Circuit

Product Description

The SIEMENS LC1224L1125 is a main lug only load center rated for 125 amps with 12 circuit spaces. It accepts branch circuit breakers directly without an integrated main breaker, making it suitable for use as a sub-panel fed from an upstream disconnect or main panel. Designed for single-phase residential and light commercial electrical distribution, this load center provides a structured enclosure for organizing and protecting branch circuits. Licensed electricians install this unit as part of new construction or panel upgrade work in accordance with NEC requirements.

This load center is used in residential sub-panel applications and light commercial installations where a dedicated branch distribution point is needed downstream of a main disconnect. Its 12 circuit spaces accommodate a range of single-pole and double-pole breakers for lighting, receptacle, appliance, and HVAC branch circuits. The main lug configuration allows the installer to feed the panel from an appropriately sized feeder with a separately located overcurrent protective device.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize the upstream feeder and verify absence of voltage before making any connections to the load center. Ensure the feeder conductors and overcurrent protective device upstream are properly sized for the 125 amp rating. The enclosure must be mounted level and secured to a structural surface before wiring.
