Electrical Code Requirements for Lights and Outlets
Background: Michael, a Homeowner from Dover, NH
I am enclosing my back deck, and running a new electrical circuit for the lights and outlets. I am planning on using 14-gauge wire for the circuit, which will be on a 15 amp afci breaker. But, I read somewhere that the national electrical code requires 12-gauge wire. Is that true? Does either a national or state (New Hampshire) code require that smallest allowable gauge wire is 12-gauge?
Additional Comments: very helpful
Thanks for your electrical question Michael.
I am not aware of your local code, however for general purpose circuits either 15 or 20 amp circuits are acceptable, however the determining factor will be the actual connected loads created by the light fixtures and the devices that will be plugged into the outlets.
Enjoy your project and don’t forget to file a permit and get an inspection. That action alone will have determined your local code requirement.
I have provided the following links that lead to fully detailed information on this website that will assist you with your electrical question:

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.
