  • Wiring a Combination Switch
    A combination switch outlet may not be installed at the location where it is the end of the three way switch wiring because there is no neutral wire present.
  • Combo 3Way Switch Wiring
    The combination switch outlet may be installed at the beginning of the three way switch location where the hot, neutral and ground wires are available.
  • Switches and White Wires
    You must keep in mind that switching does not involve a neutral wire, and just because a White Wire is present and used for switching does not mean that the white wire is a neutral wire, but in fact is most likely a white wire that is being used to as a switched power leg.
