I am trying to identify which of 5 wires is on a particular circuit. The wires enter and exit this certain space in such a manner that I cannot determine their source or their destination. The wires are typical (for US) household romex 120v/15a. I want to cut one of these wires and put on outlet on that line. If I could measure current non-invasively, I could turn off the circuit at the breaker box and then I identify the wire I want. Is there a tool to do this? If not, any other suggestions? tag:ask.metafilter.com,2008:site.79959 Wed, 02 Jan 2008 10:25:35 -0800 electricity residential romex allelopath
