It's just a matter of time when troubleshooting is going to be required at your workplace regarding an electrical problem. This problem could be as simple as a lighting circuit, or it could be as complex as a variable frequency drive (VFD) control circuit. When this time comes, it's going to require a certain skill (troubleshooting) to ascertain the problem, diagnose the circuit/component, and provide a solution to return the suspect circuit or component back to normal operation as soon as reasonably possible. What is a skill? The dictionary states that a skill is (1) A developed talent or ability; (2) An ability that has been acquired by training; (3) Ability to produce solutions in some problem domain. The ability to troubleshoot encompasses all three definitions. Definition 1 relates to the troubleshooting skill that has already been developed. Definition 3 relates that once the skill has been developed, one can produce solutions. Definition 2 relates to one aspect in the development of a troubleshooting skill. This is where HPC Technical Services comes in. This course will provide the minimum skills required in the development of troubleshooting effectively. Additionally, to hone your skill of troubleshooting, a myriad of circuits will be used that represent the ones that you will most likely come in contact with.

Also, this course will describe the importance of having an electrical preventive maintenance program.

Objectives

1. Demonstrate familiarity with Ohm's Law and the ability to apply this law in interpreting electrical circuits.
2. Describe hazards associated with working with electricity and demonstrate how to protect oneself from this hazard.
3. Demonstrate a working knowledge of the functionality of a multimeter, voltage testers, a non-intrusive ammeter; and identify the instrument that is used to verify the integrity of wire insulation.
4. Participants will have a working knowledge on how to properly select the function/range and connect a multimeter to measure current, resistance, and voltage.
5. Describe the difference between a conductor and cable and how they are classified.
6. Describe the accepted safe way of running wires from one location to another.
7. Demonstrate the proper technique on how to connect wires using a wire nut or terminal lug as well as to wire an electrical receptacle and/or switch, fluorescent ballast, AC motor, and DC motor.
8. Demonstrate knowledge regarding the use and application of different types of electrical diagrams.
