Electrical Wiring 20PTS

BASIC PRINCIPLES OF GOOD WIRING

*Before beginning any electrical repair, shut off the power. Remove the fuse or trip the breaker for the circuit you will be working on in your service panel. Use a neon tester to be sure the power is off. If there is any doubt, you can remove the main fuse or trip the main breaker.

Electrical wires are color coded to prevent wiring errors

Remember the number of lights and outlets you can wire into one circuit depend on two factors: Wire size and Breaker size

Example: On a 15 Amp circuit, you will find #14 wire. You are only allowed a maximum of 12 lights on one 15 Amp circuit, but between 8 & 10 if combining receptacles and lights.

On a 20 Amp circuit, you will find #12 wire

Your task is to draw and label the correct wires to each of the components correctly. Use a wire nut if necessary. Please see the next page.

Also, please determine the phantom load of all appliances/components in your residence. Make a table of the item name, its consumption of electricity when turned-off, but still plugged in. Electricity in the county is 6 cents/per kilowatt hour (meaning it costs 6 cents to power 1000 watts for one hour). A coffee maker uses roughly 1000 watts, for example. Please review our PowerPoint or internet searches for assistance.

Please total all consumption of power used from Phantom Loads, and include a rough estimate. You may use the examples given (tables) from the PowerPoint or via Google or other internet searches. Conclude with your findings and if you expected the results.
