Frequently asked questions about Motor Circuit Test

How are motor circuit conductors sized?
NEC 430.22 requires branch-circuit conductors for a single continuous-duty motor to be at least 125% of the motor full-load current. Feeders supplying several motors follow NEC 430.24. Always work from the nameplate FLA and the current NEC edition.
What overload protection does a motor need?
NEC 430.32 requires overload protection sized to the motor service factor and temperature rise — commonly 115% to 125% of the full-load current. The exact percentage depends on the motor markings.
