Circuit Breaker Maintenance, Medium-Voltage (CBMMV)

Circuit Breaker Maintenance, Medium-Voltage

COURSE OVERVIEW

This course provides training for the performance of visual, mechanical and electrical inspections, in accordance with manufacturers’ and NETA MTS requirements. Technicians have more components to test and maintain to ensure a 3 to 5 cycle operating time. This hands-on course is intended for new or experienced electricians and technicians that install, maintain, repair or troubleshoot air and vacuum metal-clad circuit breakers and switchgear, rated at 1 kV and higher.

Failure of one of these circuit breakers can cause catastrophic damage to other equipment and can be extremely hazardous to nearby personnel. In addition to improving electrical system reliability, well maintained circuit breakers also minimize the arc flash hazard energy levels that technicians can be exposed to during a fault.
