• Calculate short circuit current

• Discuss transformer malfunctions

Module 4: Electrical Motor Operation and Troubleshooting

This module starts with the basics of electric motors and control techniques thorough fundamental motor maintenance and identification of common electric motor failures. This module will have the students building and troubleshooting both basic and specialized motor control circuits, as well as, wiring three-phase electric motors for both high and low voltage based on the information they glean from the motor’s nameplate. The students will learn how to identify shorted and open windings by using test equipment such as volt/ohm meters and insulation resistance testers.

Learning Outcomes

• Identify the parts of an electric motor

• Explain the operation of a synchronous electric motor

• Given name plate data properly connect a three-phase electric motor

• Using test equipment identify the cause of a malfunctioning electric


• Troubleshoot open and shorted motor windings

• Clean, inspect, and repair a NEMA rated motor starter

Module 5: Motor Control Wiring and Troubleshooting

This module provides the student with the necessary understanding of motor control devices such as limit switches, motor starters, and relays and their symbols used on electrical diagrams.

Students will build common motor control stop and start circuits using real world equipment from ladder diagrams. Troubleshooting techniques will be explained and performed as part of this intensely hands-on module.

Learning Outcomes

• Identify electrical components and their symbols on electrical drawings

• Read a ladder diagram and explain the operation logic

  • Explain the operation of relays
  • Build a 3-wire motor control circuit
  • Perform basic troubleshooting of motor control circuits using test equipment
  • Interpret a common MCC bucket wiring diagram

Module 6: Over Current Protection

Over Currents Protection Devices protect equipment and conductors by opening the circuit when predetermined values or parameters are met.

Over current protection devices include fuses, circuit breakers and thermal overloads. In this module, the student will learn the different types of fuses and circuit breakers, how they operate and how they protect circuits from both short circuit and overload conditions.

Learning Outcomes

• Compare and contrast a short circuit, overload, and ground fault

• Explain fuse current, voltage, and interrupt ratings

• Discuss current limiting fuse operation

• Explain rejection type fuse holders and fuses

• Explain the operation of single and dual element fuses

• Identify the components of low voltage circuit breakers

• Discuss the operation of low voltage circuit breakers

• Explain how thermal overloads operate

What they’re saying about our Fundamentals of Electrical Maintenance Class

Explaining details between shocks, arc flash, and arc blast

“This was one of the most relatable sessions I have attended. The instructor gave many examples of workplace issues that can be encountered from a firsthand perspective. I have taken the course before, but it was good to review some of the hazards and what we can do to limit the severity of the injuries in some instances with just taking a little extra time to be safe.”
