I would like to see a wiring diagram on how to wire two switches and a receptacle in one box with a single line feed, three wires.

  • Assuming modern wiring, a single line with 3 wires in it can only be for a single switch. You can't have an outlet and two switches. – longneck Oct 15 '13 at 15:46

If you're trying to use a single cable with only 3 wires, one of the switches will do nothing.

  • As Tester101 illustrates, you need a common hot to the switches and a separate switched hot from the switches. That always equals 3 wires to control the hots. If you were not also putting an outlet in that box, you would not need a neutral (for basic switches) and could get by with a three wire, using the white as one of the hots, but correctly marked, and assuming there is a neutral at the fixture. Once you introduce an active device (the outlet), you need at least four wires, whether in one or more cables (and green/bare is not counted). – bib Oct 15 '13 at 17:19
  • @bib As of NEC 2011 a grounded (neutral) conductor is required at switches too (though there are some exceptions). See Article 404.2 (C) – Tester101 Oct 15 '13 at 17:36
  • Excellent point and I think you've told me this before. Lets hope it sinks in this time. – bib Oct 15 '13 at 18:50
