I am rewiring a bathroom. Thought it was a pretty simple job but I have run into a conundrum.
Coming into the bathroom I have one wire from the fuse box( A) and what I thought was two branch circuits going out ( C and E). I have one connected one branch circuit (E) and it is working fine but when I add the other (C) it trips the breaker.
The circuit in question (C) appears to me to be a branch circuit. It has three wires one red (which I have confirmed only goes to a light) and the usual black and one white wires.
However the black wire of the branch circuit in question and the white of the other circuit test positive for continuity when the power is off. I can’t figure out why.
In the pictures wire 2 and 5 are the one that make contact.
Help greatly appreciated.
