I love being an inspector because it seems their is always a game associated with certain inspections and the NEC. For example: Failed a service yesterday because the contractor pulled in 6 CU insulated (black) for the equipment grounds and re-identified them green at their terminations. Of course they had to be green their entire length. He calls me and tells me that his supply house cannot find 6 insulated green AL. I explaned that for this application he could pull in 4 AL per table 250.119 for his 200amp OCPD, and re-id it.
Ok well what about when his OCPD is a 100amps and he uses 6AL because guess what the price of copper is out of sight and I as an inspector have no right to say whether he uses either CU or AL. Now how does he comply with 250.119(A) if he uses 6 AL? He cannot. I have my mind made up on what to do with this one but just thought I would see what everyone else would do.
For me I opt on the side of the EC
Thanks
