Phase and Motor Rotation Test Set
(Biddle Instruments)

This Test Set provides a positive way to identify the leads of a disconnected polyphase motor, and also identify true phase sequence of energized 60 cycle a.c. power lines up to 600 Volts. Both are necessary to insure that a motor will rotate in a prescribed direction when energized.
The Test Set permits the electrician to permanently connect and tape the terminals of the motor being installed, without having to first energize the motor by a temporary hook-up to determine motor rotation. These temporary connections are time consuming and costly, and can be quite hazardous.
Two other important uses for the Test Set: it can determine the polarity of power and instrument transformers, and it can be used as a continuity tester in checking electrical circuits.

High Impact Plastic Case has deep removable lid (not shown) to store leads and instruction manual.

Input:
50/60 Hz. up to 600 Volts
