Re: Raceways

How do you plan on complying with 366.6(A)?

Re: Raceways

even given what nick says you are much better off to just use pipe large enough to give you reas9onable pulling room and derate the conductors. Assuming thhn use the 90 degree table as your starting point and apply 310.15(B)(2)(a) as needed.3 boats of thhn #12 still gives you 21 amps to work with.
