Operating from a 50,000 sq. ft. facility in Ontario, California, the company manufactures and assembles UL 891-certified equipment designed for commercial, industrial, utility, and mission-critical environments.

Electrical distribution equipment includes the components that receive, control, protect, and distribute electrical power throughout a facility. Common examples are switchgear, switchboards, panelboards, service entrance equipment, remote power panels, breakers, bus systems, and metering assemblies. These systems are selected based on voltage, amperage, enclosure type, code requirements, and the operational demands of the building or infrastructure they serve.
