    * Ampacities based upon 2023 NEC Table 310.16 and do not take into account the overcurrent protection limitations in NEC 240.4(D) of 15 Amps for 14 AWG CU, 20 Amps for 12 AWG CU, and 30 Amps for 10 AWG CU (independent of the conductor temperature rating and stranding if size is present in table). Also, see NEC sections 310.15 and 110.14(C) for additional requirements.
    * Ampacities have been adjusted for more than Three Current-Carrying Conductors.

    Color Table - Conductor number = number of phase conductors. Does not include neutrals and green ground. ( / means stripe RD/WE is Red with White Stripe)
