I feel rather stupid asking this, but I just started at a new company that is telling me I must run 6 hots and 6 neutrals(12 thhn) in my 3/4 emts. I was always under the impression I am only allowed 6ccc's in a conduit before I need to derate them. I have always ran 4 hots and 4 neutrals with ground max in any size conduit. (12 ga on 20a breaker) to keep under 9 ccc's. Also I would always run 9 hots with 3 neutrals and not count the neutral as ccc because the load would balance out. Am I wrong? In this specific application I am wiring in a hotel so the circuits would be for kitchen/bath outlets and what you would generally expect. My company claims the minimal load on the circuit would allow me to derate my wires based on the load and not the breaker ampacity.
