Thanks for your electrical question Steven.

Testers for Identifying Electrical Wiring

  • Steven, all of the wires will need to be identified in order to make the correct connections.
  • With a junction box like this there is typically power coming in, power going out and one set of wires that may be used for the switched leg of power for the light fixture as well.
  • This can only be positively verified by using a tester or a continuity meter.
