  • Determining Load Horsepower, Wiring, and Breaker Size for Safe and Efficient Installations

    “Let's just oversize the motor and we can run it lightly loaded—that will save us some money and be easier on the motor.” This is a false belief among some who select and install motors. Properly sizing motors for a given load results in driving loads more efficiently, saving energy, and saving dollars. Motors typically are most efficient when they are 90 % to 95 % loaded. Just because a motor says “25 Hp” on the nameplate does not mean the motor is producing twenty-five horsepower as it operates.Clamp meter readings: Problems and Solutions
