Module 1: Basic Electrical Theory

The lesson material will be a combination of classroom lecture and hands-on exercises that start with electrical basic theory and finish with more advanced troubleshooting concepts. The students will use breadboards to build circuits, take volt, ohm and current measurements that will verify their previously calculated values. At the completion of this module the student will be able to identify common circuit malfunctions such as opens and shorts utilizing test instruments.

Module 2: Alternating Current

At the completion of this module, the student will understand what alternating current is, how it works, and what factors affect the operation and maintenance of AC equipment such as motors, transformers, and distribution equipment.

Module 3: Transformers

Electric transformers are utilized in most electrical equipment. Transformers can either step-up or down voltages to provide a safer level for equipment controls that will be interacted with by plant employees. Even though transformers do not contain any moving parts they can fail due to improper maintenance or overloading. This module will explain how a transformer operates, how to determine the correct size, and identify common 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.

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.

Module 6: Over Current Protection

Over Current 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.

Module 7: Components for Electrical Construction

Industrial Electricians need a basic understanding of the National Electric Code to ensure that safety requirements are met when installing new or replacing old equipment. 

In this module, the student will learn the different wire types, their ampacities and how many conductors can safely be installed in conduits. Wire splicing methods will be discussed such as the safe use of twist-on connectors.

Module 8: Variable Frequency Drive Operation and Troubleshooting

A Variable Frequency Drive (VFD) is a type of motor controller that drives an electric motor by varying the frequency and voltage supplied to the electric motor.

In this module, the student will learn how a VFD operates, how to install inputs and output for proper operation, program various parameters, and troubleshoot malfunctions by retrieving and deciphering fault codes. This is a hands-on module in which the students will install, program, operate and troubleshoot real world VFD applications.

NFPA 70E Electrical Safety

This portion of the overall Fundamentals Electrical Maintenance course will focus on electrical safety. This module will explain the safety related work practices stated by the National Fire Protection Association (NFPA) 70E and required by OSHA. 

Students will obtain the knowledge and skills needed to keep themselves and other employees safe from shock and arc flash hazards.
