I had earlier asked a question on Derating and got great answers, thank you. Im still having some trouble on understanding when I count a neutral as current carrying. Ive read 310.15 b (4) a-c and just want a clearer understanding of this matter. An answer to my question earlier was if I had 3 sets of conductors a/b/c/n/g of a 208/120 wye connected system in a raceway I would only have 9 that were current carrying, this being my 9 current phases. So can I assume that in all 208/120 systems my neutral is not counted as current carrying or does it depend on the load? How about 277/480 delta systems?
