App Description
NEC motor full-load amps calculator for electricians, apprentices, and electrical engineers. Look up motor FLA from NEC Tables 430.248 and 430.250, then get conductor sizing, overload protection, short-circuit protection device (SCPD), and disconnect ratings - all per NEC Article 430. Works 100% offline on the job site.
Whether you are sizing a motor branch circuit for a 10 HP three-phase motor, selecting the correct breaker for a 5 HP single-phase motor, or verifying overload protection settings, this motor FLA calculator gives you accurate NEC-compliant results in seconds.
