I was going to replace my bathroom outlet with a GFCI outlet when I came across this weird guy. It looks like two wires are on the hot side (under a single screw!), one neutral, and no ground. This is a normal 15 amp duplex receptacle, it is not controlled by a switch although there are switches on the circuit. What might be going on here?I've closed up the box while I research via /r/DIY https://ift.tt/2LNr6u2
