I have a question on Article 334.80 where the Ampacity reduction of multiple NM thru sealed holes are covered. I think I am ok in the main Article, the question comes in where is states the Exception in 310.15 a(2) shall not be allowed.
I recently had an inspector suggest a 14/2 and 12/2 thru same insulated hole would result with being required to use Ampacity of 14/2 due to this wording and therefore OCPD for 12/2 lowered to 15 A. I can't see this logically, but reading the code doesn't prove him wrong. What does NOT Allowing the Exception mean as it applies to 334.80?
Thanks
