Credits: .7
Lecture: 6 hrs
Class Exercise: 1 hr
Total: 7 hrs

Prerequisites: None

Class Description: Participants will learn basic electrical theory, safety procedures, power distribution, and energy conservation to develop a practical understanding of electricity and its use in commercial facilities. Participants will learn basic troubleshooting in order to effectively work with licensed staff and/or contractors with ongoing electrical problems and maintenance support.

PROJECT: None

Learning Objectives:
At the completion of Facility Electrical Systems a participant will be able to:

  1. Explain the basic structure of an atom.
  2. Define voltage and identify the ways in which it can be produced.
  3. Explain the difference between conductors and insulators.
  4. Define the units of measurement that are used to measure the properties of electricity.
  5. Explain how voltage, current, and resistance are related to each other.
  6. Using the formula for Ohm’s law, calculate an unknown value.
  7. Explain the different types of meters used to measure voltage, current, and resistance.
  8. Using the power formula, calculate the amount of power used by a circuit.
  9. Explain the basic characteristics of a series circuit, parallel circuit, and series-parallel circuit.
  10. Calculate the voltage drop in series, parallel, and series-parallel circuits.
  11. Calculate the total current in parallel and series-parallel circuits.
  12. Find the total amount of resistance in a series circuit, parallel circuit, and series-parallel circuit.
  13. Identify electrical hazards and recall how to avoid or minimize them in the workplace.
  14. Explain safety issues concerning lockout/tagout procedures, personal protection using assured grounding and isolation programs, confined space entry, respiratory protection, and fall protection systems.
  15. Identify common symbols, interpret electrical drawings and describe the type of information included in electrical specifications.
  16. Describe typical preventative maintenance for an electrical distribution system and describe ways to maintain an energy efficient and reliable facility electrical system.
