This is a three-gang switch in a home I just bought. I am not an electrician by any means, so this is probably going to be a question for curiosity sake.

Is it possible to tell me which wire is what from this picture? Thanks in advance!

    I'm wondering where in the world you are that some sort of wiring splice that appears to be nothing but some electrical tape meets the modern wiring code.

  • That's not a splice, it's grouping the travelers, as longneck notes. The green hot weirds me out, but I'm aware that some parts of the world do that.

  • The red wire is the "hot" and supplies power to the switches.
  • The black wire and the green wire with the white paint are the switched hots. Those run to the light or outlets that the switches control.
  • The two green wires that are taped together are traveler wires for a 3-way switch arrangement.

  • Looks more like the red is the hot - that's the one that's connected to the other two switches by the black jumpers.

  • Well, it would certainly be clearer if they had used red jumper wire.
