I am trying to move an electrical box in my kitchen from the wall to an island. The box I am trying to move is on its own 15amp circuit but has a 14/3 and a 14/2 wire going into the box. Why are there two wires going to this box?

Are all the wires coming into the box connected to the plug? If so, only thing I can say is that maybe it's a switch controlled receptacle. Other words, possible that ONE of the receptacles (the one with the RED wire attached) is powered by a wall switch where you can turn that receptacle off and on. Unusual for a kitchen but I guess it can happen that way.


This is just my thought. Others will explain if I am wrong!

:D

First off, a couple of issues, assuming your located in the USA, #14 wire is not allowed for kitchen receptacles. All counter outlets should be 20 amp circuit with #12 copper wire. Plus, if you relocate the counter outlet to the island, what will serve that counter where the outlet was removed? Generally speaking, there should be an outlet every four feet of counter, and one at any separate space 12" or more.

Noting how the wiring was, or is connected in the outlet box is wise, before taking any connections apart. Using a voltage tester to test each wire and learn which is the feed is wise also.

Switched outlets in a kitchen is not very common, I have never seen it, I suppose it is possible.

Most likely, the 3 wire cable is two circuits with a shared neutral, one circuit feeding that first outlet, and the second circuit continuing on to another outlet.

Noting how the wires are connected and using a voltage tester will help understand this arrangement.

I agree the 14-3 is either a switch leg maybe for under counter lights, or 2 separate circuits, red and white would stop there, the black and white would continue to another circuit.
How are the red and blacks connected in box?
