I know kind of which wires are which in a wall switch, but do not know what one wire is i do not need, just curious. Maybe something that was capped out when things were re-wired, who knows. So here’s the picture:
There are no grounds in my case, full metal conduit in the house and metal boxes. The white wire is hot. The yellow wire is the traveler. But you will also see that red wire that is capped off and connects to nothing. Any idea what this red wire would have been used for?
My best guess maybe from a switched outlet that is no longer switched?
For reference this currently powers a Lutron dimmer switch.
