Table B - Minimum Wire Sizes for Single Phase Motors
* Type S, SO, SJ, SJO, etc. Flexible cable wire sizes. See NEC Article 400 for ampacity.
NOTE:
NEC Article 310-5 --- Minimum conductor size for general wiring at 115-440VAC is
No. 14AWG.Above wire sizes based on approximate 5% voltage drop during starting; copper
conductors; and 75° C type THHW, THW, THWN, RH, RHW insulation, etc. For aluminum
wire, increase two wire size steps minimum. See NEC Article 310 for ampacities of aluminum
conductors.
