Medium-voltage and low-voltage switchgear installation, paralleling switchgear for generator plants, and UPS-tier critical distribution. UL 891, ANSI C37, and NETA-acceptance tested.
Switchgear is the heart of any serious facility’s electrical distribution. Done well, it’s invisible — the building runs, the redundancy works during a failure, the operator never thinks about it. Done badly, it’s the single biggest source of facility downtime and the most expensive thing to fix after construction is complete. We treat switchgear with the seriousness it deserves.
Our switchgear scope covers MV (metal-clad), LV (UL 891 switchboards and UL 1066 switchgear), generator paralleling switchgear, and UPS-tier critical distribution. We work the major manufacturer platforms and have field experience commissioning all of them.
Indoor and outdoor MV switchgear per ANSI C37.20.2 and C37.20.7. Vacuum circuit breakers up to 5kV, 15kV, 25kV, and 38kV ratings. Eaton VCP-W, ABB ZS1, Siemens 3AH4, and Schneider Masterclad platforms. Arc-resistant construction where the application requires it.
UL 1066 low-voltage power circuit breaker switchgear and UL 891 switchboards. Mains from 1,600A through 6,000A at 480V/208V secondary. Drawout breakers (Eaton Magnum DS, Square D Masterpact, ABB Emax) and molded-case feeder breakers.
Paralleling switchgear for multi-generator standby plants. Sync controllers, load-share modules, and PLC-based plant master controls. ASCO 7000-series, Russelectric, and Caterpillar EMCP-based platforms. NFPA 110 Level 1 compliance for life-safety applications.
Critical bus distribution from UPS output through STS, RPP, and PDU. N+1, 2N, and 2(N+1) topology installations for data center and healthcare applications. Concurrent-maintainable distribution and bus tie configurations.
Microprocessor relay protection (SEL, Schweitzer, GE Multilin), digital metering (ION, PowerLogic), and integration with facility SCADA. Coordination studies, arc-flash analysis per IEEE 1584, and protection selectivity verification.
NETA ATS testing on installed switchgear including insulation resistance, contact resistance, breaker timing, and primary/secondary injection of protective relays. Functional testing of trip schemes prior to energization.
We’re manufacturer-agnostic. Each project specifies its own gear — we install what the engineer of record specifies and what the owner has standardized on. Common platforms we work with regularly include Eaton, Schneider Electric (Square D), ABB, Siemens, Vertiv (for critical distribution), and Russelectric (paralleling). We have field experience with all of them and don’t need to learn on your project.
