Electrical – How to extend a cable to move an outlet inside a kitchen island cabinet

electricalislandreceptaclewiring

Due to remodeling, I need to move an outlet in my island. The current system is wired as follows: a 12/2 NM wire comes from the circuit breaker box to the first (non-moving) outlet, and a 12/2 wire runs from there to the second outlet. I can't just direct this wire to the new location because it is too short to reach. Also, there is not enough slack to pull the first outlet out to connect a new longer wire.

Therefore, my plan is to cut the wire from the circuit breaker and route it to a junction box. From there, I would run a longer wire to each of the outlets. I tried to verify this was to code, and came up with some questions (everywhere I look for the NEC tells me that copyright prohibits putting it up in its entirety, or what I found was so convoluted that I don't understand it exactly):

  1. Lots of places have said or implied that you can't put a junction box in a cabinet, but others say that it just needs to be accessible, i.e., not behind a wall or cabinet. Can I put a jxn box on the back wall inside the cupboard where I store pots/pans?

  2. Is AC cable required, or can I just use NM? Some sites have said AC is required, but i'm not sure why.

  3. Is there a better plan?

Thanks.

First of all, figure out if the original wire is stapled or not. If it isn't then the solution is easy.

CAUTION: Requires work IN the panel. If you are not 100% confident you can do this safely, call an electrician. It's not difficult, but you need to know exactly what you're doing.

  1. Turn off breaker.
  2. Cut pretty close to the box.
  3. Use this slack to do what you need to do upstairs. -- free fixed outlet, new wire to the one you want to move.
  4. Mount a junction box a couple of feet from the panel in the basement.
  5. Find a piece of cable that will reach from the new junction box to the panel. (Maybe there's some old wire we just removed lying around?)
  6. Splice in the junction box, and find someone to connect it back to the panel.
