Tomorrow I will find the breakers for both sides of the bottom pair and see if I can figure out where all these wires come from / go to.Electricity is a major topic in GCSE Physics. I also have no idea how this was ever working, but I swear I have changed no other wiring - the only thing I can think of is replacing the other outlets did something to a loose connection somewhere. I have not had the time to go find what breaker(s) control the bottom pair, but I do think that the top pair comes from the switch box in that room.

The yokes on the hot and neutral side for this outlet are intact.

If I remove any of the four wires which lead to this outlet, the lights in my entry way (which are on a different breaker entirely) stop working.I also have 112v from neutral to ground and 116v from hot to ground on the bottom pair (yes seriously).

With the breaker (#9) for the bathroom off I have 0v from neutral to ground and 0v from hot to ground on what I will call "the top pair" (since that's where they come into the box).

Saturday I replaced some other outlets in my bedroom and despite changing literally nothing else (and that bedroom being on breaker #11), the breaker (#9) for the bathroom tripped and won't reset. If any electrician thinks I'm wrong or has any insight for me please let me know, I've only been in the trade 3 years and have a lot more to learn. ~240v would mean you do in fact have two 120v circuits on separate phases of your panel coming into that single gang boxĠv would also mean you have two circuits coming into that single gang box but that they share the same phase on your panel. ~120V would mean you do not have two circuits in one box, as only one black wire has 120v going to it If you take a multimeter and do a voltage test across both of the black wires with all the circuits on then here's what you should have and what it means:

If you really do have two separate circuits in the box, you should be able to disconnect one pair of black and white (coming from the same sheathing of course) and it shouldn't affect anything down stream as it /should/ be a dead end for that circuit /if/ there truly are two circuits in the box. I'm curious to know if you really have two circuits in one box, and only two pairs of Black and White.
