Course Description

Residential electrical construction, wiring principles and practices, study and application of NEC code to comply with building requirements. Transfer Credit: CSU.

Course Level Student Learning Outcome(s)

Properly install a branch circuit with all the components sized per the NEC (National Electrical Code) and install any type of switching, receptacle or light fixture that will be on that circuit.
Determine the difference between 120 volt circuits and 240 volt circuits in any type of electrical panel and be able to calculate the appropriate size in amps with the use of electrical math equations.

Course Objectives

1. Use the index of the National Electrical Code (NEC) to identify specific codes that are relevant to residential buildings.
2. Identify the basic components of a residential wood framed house.
3. Read a measuring tape rapidly and accurately to the nearest 1/16th of an inch.
4. Read and comprehend electrical definitions and terminology of the NEC.
5. Apply the appropriate formulas for problem solving of load calculations for a residential home.
6. Recognize and properly name various connectors, conduit, fittings, and boxes necessary for the installation of receptacles and switches.
7. Draw an appropriate wiring diagram for single pole switches, three-way switches, four-way switches, split receptacles and duplex receptacles.
8. Calculate the appropriate box size per the NEC.
9. Calculate the appropriate wire size per the NEC.
10. Use Ohms law to perform calculations to determine volts, amperes, and watts.
11. Determine the proper spacing for receptacles for general purpose branch circuits
12. Determine the proper locations for smoke detectors.
