"THHN" is "THHN" and when we use words here, or terms that are read by some who are not as familiar with our trade we should be exact.
Sure, I knew what was meant, but still feel we should all strive to be very accurate, in fact look at what I found here:
http://www.southwire.com/wc/catalog/sec32/32-1.htm I found an installation that used straight THHN in an underground run last year in a brand new installation!
