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?

Thanks

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.
