Have a electrical problem with a Pass Seymour Timer switch on a bathroom remodel I am currently undertaking. Attached is a rendering of the wiring involved:
To explain, I had turned on the timer for the bulb heater. Worked fine. I went over to the 3-pole switch and hit the NUTONE vent fan switch first and the switch popped loudly and died. There was a small black mark on the back of the switch. Both circuits tripped at the panel. The GFCI tripped also. I pulled the timer switch out. I took the bare hot lead and sent power to the bulb heater. It works fine. I turned on both vent fans at the 3-pole switch and put power to it again, works fine. Nothing tripped and everything works.
Wondering if anyone can find any wiring problem in that diagram that might have caused this before I put another $29.00 switch back in.
I did read somewhere, probably here, that putting a GFCI downstream from another GFCI was a no-no. I put one in for the refrigerator because it is right below the shut-off valve for the water line for the icemaker. Probably not necessary and I am going to switch it back out or put in a GFCI breaker. The circuit has worked trouble free for about 2 months since I first ran it. Nothing like this at all. The other point is where I wired two neutrals together at the NUTONE unit from two separate circuits. I would have thought that if this is a problem, it would have tripped the breaker at the panel immediately.
Thanks, in advance!
