Our Circuit Breaker Testing Training course is a practical, instructor-led program on electrical circuit breaker testing, maintenance and troubleshooting for medium and high voltage vacuum, SF6, oil and air circuit breakers, from 2 kV distribution switchgear to EHV transmission breakers. Participants learn how breakers interrupt fault current, how mechanisms and DC control circuits fail, and how to perform and interpret every major test.
This 12-hour instructor led course follows NETA circuit breaker testing practice (ANSI/NETA MTS and ATS), NFPA 70B 2026, NFPA 70E and CSA Z462. It gives utility, industrial and commercial maintenance teams a standards-based framework for safe, condition-based breaker maintenance.
The circuit breaker is the only device in a power system that can interrupt fault current. When one fails to open, a fault that should clear in cycles turns into breaker failure tripping, a wider outage and serious equipment damage. Most failures start in the operating mechanism, the control circuit or degraded lubrication, and regular circuit breaker testing finds all of them early.
NFPA 70B 2026 now requires a documented electrical maintenance program, with equipment condition assessments, defined intervals and audit-ready test records. Many organizations still maintain ageing breaker fleets on fixed schedules, and the experienced technicians who know how to read test results are retiring.
This course closes that gap. It moves past manufacturer manuals and teaches step-by-step circuit breaker testing procedures, the right circuit breaker testing equipment for each test, and how to turn timing, travel, contact resistance, power factor and SF6 gas results into confident decisions to maintain, refurbish, retrofit or replace.
The course uses practical, example-based instruction drawn from real utility and industrial breaker fleets.
