About this course…
Students will learn the electrical operating and control systems of a variety of low and medium voltage circuit breakers, switches, motor control centers and contactors. Topics will include safety a operation, troubleshooting and correcting operating problems to ensure safe, correct and reliable operation. This includes an overview of low- and medium- voltage circuit breakers, and external systems essential for proper breaker operation such as switchgear cubicles, switches and motor control centers.
Who should attend…
Operators, facility engineers, first line supervisors, and others responsible for managing day to day operations of electrical systems and maintenance. Intended for those whose duties may include circuit breaker operation or supervise those operations.
