Overcurrent Protection II - Coordination

This 3-hour interactive online course reviews the principles of operation and coordination of electric system equipment during faulted conditions. Since short circuits have such damaging impacts on electrical equipment, their impact on the components in the circuit must be understood.

The purpose of this course is to explain how the various protective devices react to faulted conditions and how to select the appropriate devices to ensure proper coordination. The theory of operation of protective devices is reviewed as well as how to properly coordinate the devices for selective coordination. Various electrical devices are reviewed including fuses, current limiting fuses, circuit breakers, transformers, conductors, busways, and motor controllers.
