Wiring to Replace Timer Switch with Single Pole Switch
Have a timer switch that stopped working. Bought a newer model, but the size is bigger and won't fit in electrical box. Now looking to replace with a simple single pole switch.
The box has a 14/2 (black/white) wire entering bottom, and a 14/2 (black/white) wire exiting top as well as a 14/3 (black/white/red) wire exiting top.
All wires and switches had grounds hooked up, but I will ignore for this conversation.
The original time switch had a red, black and white wire exiting it.
The box was wired as follows:
- All 4 black wires were together in a wire nut.
- All 4 white wires were together in another wire nut.
- The two red wires were connected in a wire nut.
I assume the red wire in the 14/3 wire feeds the light that the timer switch controlled. Not sure what is fed by the other 2 black wires exiting box.
I removed the old timer switch and wired a single pole switch as follows:
- All 3 black wires were together in a wire nut. I then pig tailed the black wires to one of terminals on the switch.
- All 3 white wires were together in another wire nut.
- The 1 red wire was connected to the other terminal on the switch.
When I turned the circuit breaker back on, and then turned the light switch on, the circuit breaker immediately turned off.
What's wrong with this wiring?
You have a short on your red wire if the switch is off and the breaker stays on. Check to see if your red wire got skinned. Your 14-2's would be your power in and power out to another switch down the line.
I think that was it, a short
I removed switch and undid the wiring. Inspected wires and they appeared to be fine. Tested with multimeter and what I suspected was right as to which wire was the feed and which went to the light in question. I did notice the ground wire off the switch was bare, so I replaced with a sheathed wire, rewired switch and now its works.
My speculation is that the bare ground was touching a terminal on the switch and shorting it, if that's possible.
Thanks for your help.
