Mechanics have an increasing need to work safely around electrical components.  Simply put, this Seminar is intended to (1) emphasize how to be safe from a practical perspective, and (2) provide knowledge regarding the minimum skills required to accomplish the most common tasks.  As we know, the ability to work safely and reliably on electrical equipment systems can be dependent upon an individuals' knowledge of electrical safety, use of electrical test equipment, grounding systems and electrical print reading. This Seminar is intended to help develop these skills and their application.

Topics include:  Production of Electricity, Safety Issues, Test Equipment, Use of Test Equipment, Wire Selection, Installing and Wiring Equipment, Print Reading, Introduction to Electrical Service, AC/DC Motors, National Electric Code, Troubleshooting Techniques.

Upon completion of this Seminar, the participant should be able to:

  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 multi-meter, voltage tester, a non-intrusive ammeter; and identify the instrument that is used to verify the integrity of wire insulation.
  4. Describe the difference between a conductor and cable and how they are classified.
  5. 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.
  6. Demonstrate knowledge regarding the use and application of different types of electrical diagrams.
  7. Demonstrate knowledge as to what constitutes an Assured Equipment Grounding Program.
  8. Demonstrate operational knowledge and ability to use a Ground Fault Circuit Indicator (GFCI).
  9. Demonstrate a basic understanding of troubleshooting techniques involving branch and control circuits and the importance of the Lockout/Tagout concept.
  10. Demonstrate knowledge regarding the purpose of the National Electric Code (NEC).
  11. Describe why and how electrical circuits should be checked de-energized
  12. State the factors affecting insulation resistance.
  13. Describe the three purposes of insulation resistance testing.
  14. Describe the requirements for equipment grounding and ground conductor selection.
  15. Demonstrate the ability to interpret logic diagrams.
  16. Describe the fundamental design, construction, application and operation of all motors typically found in an industrial site.
  17. Explain how a 3-phase motor direction of rotation is reversed.
  18. Define torque, starting current, and armature reaction as they apply to a DC motor.
  19. Describe the methods for determining various motor connections.
