I have a junction box in which a neutral from one 2-wire cable is spliced to a hot from another 2-wire cable. Is it possible this is right?
I am currently learning about wiring as I try to untangle the problems in my new house. So idk if this is ever a thing that would legitimately happen. The thing is, there are two fixtures that I know of connected to this breaker (even though there are 3 cables) : one receptacle that works, and one that doesn't. So I want to say "eureka!" and just fix this box so it's all black-to-black and white-to-white. But I want to be sure before I do, especially since idk where that other cable even goes.
My voltage tester tells me that 1 and 2 have power, but 3 does not. To me, this looks like #1 is wired correctly, #2 is incorrect but works b/c it has a complete loop thru #3, and #3 is incorrect and does not work b/c it has no hot wire. So I suspect #1 is my working receptacle, #3 is my non-working receptacle (and I have no idea what #2 is).
Bonus question: That dead receptacle has worked in past, and died without explanation. Is it possible that if whatever is connected to #2 is switched on, that the receptacle on #3 would temporarily have power?
