2 questions - vanity light and romex with no power
Looking thru what appears to be a great site. Working on remodeling bath.
I am adding an exhaust fan and 2 vanity light bars to the existing 3 light circuit. The existing circuit has bath light, light in adjoning laundry room, and the outside patio light. BEst I can tell that's all that's on it. I put in a junction box last night to keep from adding two more 12-2s to the exisiting ceiling box. the junction box is full now, too, so I thought I'd drop the 12-2 for 2 vanity light bars (4 bulbs each). To that I will switch them between themselves lower on the wall. One switch for both lights. I also figured that the exhaust fan could come from the vanity light junction. More or less putting vanity lights in the middle of a circuit run, right? How do the two lights and switch wire up? I think I can add the exh fan wire to that connection.
Second question: bath had a little thermostat knob controll by bathroom wall. WE also found some romex taped out behind the paneling (!). No power to either apparently. So when I was in attic, I found these wires and looked for their runs. Seems like one run goes toward the panel, but can't see for sure. At anyrate, I can't find any power to it, from any of the breakers. I flipped the off ones on and tried everything I could to energize them, to no avail. I cut the romex in the attic, stapled it to a rafter and wire nutted the ends of the wires apart about 6 -8" from the wood and spread the ends apart.. It's haning in space up there, but away from everything and itself. Will that be okay?
