      Thank you for your comment. This is based on Current Carrying Conductors only. You would only include the neutral if it was considered carrying full load current. See CEC rule 4-004 (3) and (4).

    How to deal with conductors having different insulation ratings (2 of 90, 1 of 75) placed together in raceway ambient temp more than 30 say 50.

    • @CECwithJAshton

      In this situation you would base your conductor ampacity on the lowest insulation temperature rating. Once you have determined that, then you you derate the conductors according to table 5a of the CEC.

    If 5A derate 0.71, 5C derate 0.5, what is the total derate?0.71x0.5=0.355?

      Thank you for your question. You can treat each deration individually. It will not matter if you do Table 5A or 5C first.
