Calculating the Circuit Size for Lighting
Electrical Question: I want to put 2 to 3 68 watt fluorescent ceiling lights, 1 ceiling fan rated at 39 watts and 1 duplex wall outlet on a 20amp circuit. I can do away with one fluorescent light and the wall outlet if needed.
This electrical question came from: Neil, from Rogersville, Tennessee

How to Determine the Circuit Size for Lighting Based on Watts
- Neil, you are on the right track to determine the wire size of the electrical circuit. Adding up the total number of watts is the best way to see what the actual load will be.
- There are typically two circuit sizes that can be used for home lighting:
- 15 amps, 120 volts which has the rated capacity of 1800 watts.
- 20 amps, 120 volts which has the rated capacity of 2400 watts.
- These calculations are based on 100% power factor.
- Keep in mind that an electrical circuit should be loaded to 80% of the rated capacity.

The Safest Way to Test Electrical Devices and Identify Electric Wiring!The Non-Contact Electrical Tester
This is a testing tool that I have had in my personal electrical tool pouch for years, and is the first test tool I grab to help identify electrical wiring. It is a Non-contact tester, [amazon.com], I use for the detection of Standard Voltage in Cables, Cords, Circuit Breakers, Lighting Fixtures, Switches, Outlets and Wires. Simply insert the end of the tester into an outlet, lamp socket, or hold the end of the tester against the wire you wish to test. Very handy and easy to use.
