Let’s take a closer look at the NEC. The issue here is 310.10 that states, "No conductor shall be used in such a manner that its operating temperature exceeds that designed for the type of insulated conductor involved. In no case shall conductors be associated together in such, with respect to the type of circuit, the wiring method employed, or the number of conductors, that the limiting temperature of any conductors, that the limiting temperature of any conductor is exceeded.”
