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.

  • Utilize appropriate personal protective equipment and safe work procedures for breaker maintenance
  • Interpret and utilize NEMA breaker maintenance procedures
  • Perform complete circuit breaker maintenance and restoration procedures
  • Perform and evaluate the results of contact resistance, insulation resistance and overcurrent current injection tests
  • Verify trip device operation by calculating high current test values from manufacturers’ trip curves
  • Verify operation of accessories including shunt trip, under-voltage trip, electrical operator, auxiliary and alarm switches
