My next question is that if you have a conduit with 6 #10 current carrying conductors, this conductors are rated for 80% of it's max amperage right. So there is a foreman who am working with right now that is running a 1 " emt and he says that you could run 16#10 in a 1" and still be rated for 80%. is this right or does this 16 wires fall under the catergory of 50% based on 310.15B2a. Thanks
