suobs Posted June 2, 2013 Report Share Posted June 2, 2013 Am I allowed to use 3-wire (plus ground = 4 wires) NM cable for a connection that only needs 2 conductors (+ ground)? If so, how do I flag the wire that's not being used? Can I just put a screw-on splice cap over it at both ends? Quote Link to comment Share on other sites More sharing options...
Marc Posted June 2, 2013 Report Share Posted June 2, 2013 I don't flag them. Just leave them be. A bare copper wire tells you what it is. Marc Quote Link to comment Share on other sites More sharing options...

If you want to put a cap on it, go ahead. Quote Link to comment Share on other sites More sharing options...
