I have 3 bundles of 3 12AWG THHN wires each,
- black-white-green (red tape)
- black-white-green (blue tape)
- black-white-green (black tape)
these 3 bundles come out of the load center and into 1/2 EMT. So 9 wires total, 6 of them current-carrying. (With 6 CCC's, I derated them 80% from 30A and put them on 20A/15A breakers)
At any rate, to avoid mixing up which neutral/ground goes with which hot, etc., at each junction box where two or more bundles exists, I have them bound together with colored electrical tape so as not to confuse myself or the person following behind me.
In the load center the bundles are marked with their color just as they go out into the conduit, then again at a junction box where they go their separate ways. Actually at any place where two or more bundles co-exist.
Is this going to trip out the person who follows me, or worse yet, be dangerously misleading?
