My house was built before computers, or television for that matter, and one circuit has everything plugged into it. I have not had a problem yet, but it has to be getting close.
There is a 3way switch by the backdoor on the circuit, which goes to a switch by the front door with a 3wire and then to the ceiling fan/light. The front door switch shares a box with another light on a lightly used circuit.
Can I:
1) At the back door, replace the feed hot with the white that now goes to the other switch. (nutting the old wires and putting black tape on the white wire) 2) At the front door, replace the white wire (now coming from the other switch) with a black feed from the other switch in the box, attach the black wire going to the light with the white wire (again, marking it with black tape) from the other switch, and connect the white wire coming back from the light to a white wire already in the switch box.That will reduce the load on the heavily used circuit by a few amps. I think this will work, but it is sufficiently confusing that I might be mistaken. Thanks.
