Core Services: Switchgear & Breaker Focus
Switchgear Servicing & Maintenance
Full preventive & corrective service: thorough cleaning, torquing bolted connections to spec, lubrication, visual/mechanical inspections, insulation resistance testing, DLRO/contact resistance (ductor) testing, busbar checks, and functional verification. We test to NEMA standards to keep your 480V+ systems reliable and minimize downtime.

Circuit Breaker Testing
Primary injection testing to verify trip units, timing, pickup values (long-time, short-time, instantaneous, ground-fault), plus DLRO/ductor contact resistance testing to detect high-resistance through contacts that could cause overheating or failure. We test low/medium-voltage breakers to NEMA standards with calibrated equipment—ensuring precise coordination and protection.
