Motor Full-Load Current NEC 430.248 / 430.250

Full-load current values for sizing conductors and overcurrent protection — not the motor nameplate.

Field Note
Use these values for sizing conductors and overcurrent protection — not the motor nameplate FLA. NEC 430.6(A)(1) requires using these tables instead of nameplate current for conductor sizing and overcurrent protection.

Got your FLA? Use the Wire Size Calculator to find the right conductor.
