Electrical Code Requirements for Lights and Outlets
Background: Michael, a Homeowner from Dover, NH
[ad#block]Question:
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?

Thanks,
Mike

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.
