It is also important to realize that even at low horsepower requirements a motor still draws a relatively large amount of current. Installing larger conductors and breakers than needed is a wasted expense. If the motor constantly runs at these reduced horsepower requirements money is being wasted and you should consider replacing it with a correctly sized motor.Īdditionally, sizing of conductors and the fuses or circuit breaker supplying that motor are based upon the full load current rating of the motor, how often it is expected to operate, and other factors. The motor may be producing quite a bit less depending on the load requirements.
Just because a motor says "25 Hp" on the nameplate does not mean the motor is producing twenty-five horsepower as it operates. Motors typically are most efficient when they are 90 % to 95 % loaded. Properly sizing motors for a given load results in driving loads more efficiently, saving energy, and saving dollars. This is a false belief among some who select and install motors. Or, you can center the jaws of a clamp meter around a single conductor. Fluke virtual demos and product selectorsīy Randy Barnett Run a Fluke iFlex™ Flexible Current Probe around a single conductor.
