  1. Ken says:

    I am remodeling my basement. I purchased a 250′ of 12/2 yellow Romex and a few 20 amp breakers to add in to my panel. My question is: can I use the 12/2 Romex to wire standard outlets and lighting the same as I would the 14/2? or can this hurt anything. Just want to be safe. Thank you, Ken

  2. Dave Rongey says:

    Ken,
    The most common general purpose circuits in the home are 15 or 20 amp, for outlets and/or lighting. The two amperage ratings cannot be inter-mixed. The exact code requirements which indicate the circuits that are to be installed always start with the area and the application, then the codes are identified and applied. Several home projects are installed wrong because the codes are not understood, this is why I stress the importance of getting a permit, where in most cases your local building department will identify what codes apply and the circuits that will be required.
    Do it right the first time, you’ll sleep better at night!
