Hi all, I moved into a new house and, of course, have ran into a number of issues. The other night during heavy usage, power to the oven went out. The box revealed no tripped breakers. Multimeter is showing no power at the plug but does show 120V at every terminal except one of the unused nodes third from the bottom on the right. Voilà! Right? Well, maybe not. Truth be told, I can’t figure out which of these actually controls the oven. From what I can tell, it certainly isn’t wired to code since the only 2 pole breaker in the box is running to the dryer. The questionable breaker has one black wire headed down below the box, but not the other red one I’d expect to find since there’s one coming from the plug at the other end. Time to give it up and call the electrician or do you folks have any insight? Panel pictured .

Hello i had an existing outlet in bathroom that is protected by a gfi in another room. I am changing it to a 2 gang box with an added light switch. ( so outlet and switch) switch will power 2 lights over vanity mirrors. There are currently 2-14/2 Romex wires coming into the box and connected to the outlet so does it matter which hot ( black ) wire I get power from to go to switch? I’m thinking I can just pigtail a wire from a post on the receptacle or should I remove the wire and split the wires in a wire nut with one going back to receptacle and the other powering switch? I already ran wire from the new box to the light fixtures thanks !
