iwire,
Interesting point comes up when you say...
Use a larger cable assembly on a 15, 20 or 30 amp circuit and the factory EGC will be to small.
Run 8/2 UF for a 20 amp circuit to some far away load and the 10 AWG EGC will be a violation.
The point being that if you start with a short section of #14, 12, or 10 cable, (which have full size grounds) and then transition to your larger conductors, no violation would seem to occur because all the total line resistances would be equal, correct?
BTW,
How does one "clip a quote" to paste into a reply?
Thanks for everything guys!
