I'm trying to remove a light switch that was part of what I believe was a 4-way (possibly just 3-way) ceiling fan setup in the past. The switch is no longer serving any purpose (it didn't appear to control anything), so I've removed it and I'm now left with the below wiring. I've checked with a 2 prong voltage tester that only 1 of the wires has voltage running through it (with 1 prong touching the wire being tested and the other prong touching the GROUND wire). The remaining switch visible in the picture will be left as is for now.
The bare wire is the GROUND wire. The black wire with the exposed copper loop in it is the LIVE/HOT wire that lit up a light on the voltage tester. The other black (NO VOLTAGE 1) and red (NO VOLTAGE 2) wires didn't have any current running through them. There is also a neutral white wire visible in the back of the box, but that was already capped off when I removed the switch cover so I'm not concerned with it.
I now want to cap and seal off the exposed wiring with electrical nuts.
- Do I need to do something special with the GROUND wire, or can I leave it as is?
- Do I need to put a nut on the LIVE/HOT wire?
- Should I cap the (NO VOLTAGE) wires with a single nut, or does each need its own nut? Out of curiosity, if they need to be separate, what would happen if they were to touch; or were to touch the LIVE/HOT wire?
