Molded and insulated case circuit breakers are designed to be disassembled, inspected, adjusted and cleaned and require testing and maintenance to ensure system reliability.

This hands-on course is intended for new or experienced electricians and technicians that install, maintain, repair or troubleshoot molded or insulated case circuit breakers, rated less than 1 kV, equipped with thermal, magnetic or solid state tripping devices. Participants in this course will be required to perform visual and electrical inspections on the circuit breakers and their auxiliary devices. The electrical inspections provide data regarding the condition of the insulation, contacts and operating mechanisms.
Who Should Attend
This hands-on course is intended for new or experienced electricians and technicians that install, maintain, repair or troubleshoot molded or insulated case circuit breakers, rated less than 1 kV, equipped with thermal, magnetic or solid state tripping devices.

Circuit Breaker Maintenance, Low-Voltage
- Course 134.
- 1 Week.
- 3.6 CEU.
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.
Who Should Attend
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.
