Estimate the Full Load Amps (FLA) of a 3-phase motor given its horsepower and voltage. Crucial for sizing circuit breakers, fuses, and thermal overloads.
This is an estimate. Always check the motor nameplate for the exact FLA, as it varies by manufacturer and design class.
FLA is required to size the wire, circuit breaker, and thermal overload protection to prevent fire hazards.
Rule of thumb: 1.2A/HP @ 460V
