Electricity Wiring Diagrams
Objectives • Determine the type of wire needed for circuits with on a handout with 80% accuracy. • List the rules for wiring a single pole and three way switch with 100% accuracy. • Demonstrate how to wire a variety of circuits on a handout with 90% accuracy. • Explain the role of the National Electric Code on a handout with 80% accuracy.
Reasons to Learn • Why do we need to know how to diagram an electrical circuit? • Why are there various types of circuits in a house?
Questions to Answer • What are some different types of circuits in a house? • What do we need to know before we can diagram a circuit? • What is an advantage of diagraming a circuit? • What are some rules for diagraming a circuit? • How do you choose the correct wire?
National Electric Code • List of standards for the safe wiring of electricity. • Can be adopted by state or local governments. • Important because it holds people accountable for their work. • Keeps people safe.
KEY • Cable • Hot wire • Neutral wire • Ground wire • Re-identified • Solder less Wire Connector
