We specialize in the design and manufacturing of UL 891-certified switchgear ranging from 800 amps to 4000 amps, tailored to the most demanding power distribution requirements.
Our switchgear is engineered to meet exact specifications, built to last, and compliant with the highest U.S. standards—including UL 891.
We build UL 891 switchgear for a wide range of voltage systems and wiring configurations, each carefully designed to meet your project’s specific load, layout, and environmental requirements.
Every UL 891 low-voltage assembly is fabricated in-house and factory tested in Jurupa Valley, California, before it ships.
Every switchboard we build is fully custom, built to match footprint limitations, integration needs, and service conditions. We offer:
Flexible access options simplify installation, wiring, and maintenance in any switchgear configuration.
Adaptable entry and exit designs fit site constraints and streamline cable routing.
Choose draw-out or fixed breakers for safe operation and simplified maintenance.
Custom configurations enhance system redundancy, load management, and operational flexibility.
Durable NEMA-rated enclosures ensure protection in both indoor and outdoor environments.
Integrated coordination delivers power control with generators, transfer switches, and load banks.
