I have an existing overhead light that is not in the middle of the room where we would like it. I have installed a new round junction box in the desired location and have run a 14/2 romex extension between the old box to the new one. The old box is really crammed full of wires and connections. The light fixture is connected to a bundle of 4 white wires on one lead (large red cap) and to a single white wire on the other lead (small yellow cap). I assume that the bundle is the circuit ground and the single white wire runs from the wall switch. But I thought that any white wire running from a switch that might be hot is supposed to be taped with black or red tape. Is that not the case?
Anyhow, I connected the black wire of the extension to the single white. Maybe that makes it right. Any advice? I don't want to create or continue a code violation.
BTW, this light is on a 15-amp breaker, so the 14/2 is to code.
