Circuit Breaker Maintenance, Low-Voltage

Participants in this class will visually and electrically inspect circuit breakers according to manufacturer and NETA MTS requirements. This hands-on course is intended for new or experienced electricians and technicians that install, maintain, repair or troubleshoot power circuit breakers, rated less than 1,000 VAC, equipped with electromechanical or solid state tripping devices. Based on results of the tests, technicians should be able to make pass/fail decisions on circuit breakers. In addition to improving electrical system reliability, by ensuring optimum fault clearing times, well maintained circuit breakers minimize the arc flash hazard energy levels that technicians can be exposed to during a fault.
