Question: Mike, from Shiloh, Illinois asks: I am moving some wiring boxes in a bathroom, one of which has a wire to power a light in another room. To manage the number of wires in that box, I would like to move the wire for the light to a box connected to a GFI circuit. Is that OK? Answer: Mike, Sharing a junction box with other wires of the same voltage but different circuits is fine to do.

What is not allowed is to mix voltages in the same box that does not have a partition. Just be sure to keep the circuit wiring identified and straight forward so that the connections are not shared, only the junction box. Ask a Question! See How to Wire it Right! Do You Need Electrical Help?
