Tom, this is the sad part...
The particular AHJ in question is actually the best choice of the four available as far as code knowledge.
The first AHJ I have used doesn't do it anymore... He was "too nice a guy" in my opinion... Not AHJ material at all. He was the one that always irked me by tightening all of my terminations.
The second AHJ I used, I have only called once, and that was in Hinton, WV. He was OK, and gave a decent inspection, but lives too far away for regular use.
The third AHJ I've used is the one that uses shallow metal boxes and complains of them shorting out when powered up... However, he's the only AHJ to ever actually quote code... he quoted 250.66 to let me know that I could've used #6 instead of #4 for the GEC... He's also the one that says torqued lugs will just loosen up anyway...
Then, there's the one in question, he's been pretty good and the only one with the General rating as well as the One and Two Family Dwelling Rating...(the one that broke a meter lug once, and now doesn't "check torque" anymore) but he did baffle me on the phone this morning when he said that #2 Al woud be OK for a 100A commercial service (Construction Trailer). That's when I decided I better ask y'all... (I analyze things to the nth degree, apparently...)
What size Al and Cu should be used?
#1 Cu THWN? (60ºC Column)
#1/0 Al RHW-2? (60ºC Column)
And if the Disco and Meterbase have a labelling saying 75ºC, then:
#3 Cu THWN?
#1 Al RHW-2?
As unsure as I am of myself, I'm the most code knowledgable sparky in Greenbrier County (That I know of). It's really that sad, I'm not bragging, I'm complaining!
