Complete phase-sequence and motor-rotation testing in one instrument Ensures correct phase hookup in one easy test Rugged and portable tester Performs additional polarity and continuity checks Motor and Phase Rotation Tester permits the electrical contractor or industrial maintenance electrician to permanently connect and tape the terminals of the motor being installed, without having to first energize the motor by a temporary hookup from a power source, if available, to determine motor rotation. Therefore, the test set eliminates the need for temporary connections that can be time consuming, costly and quite hazardous, particularly where many large, high-voltage motors are involved.
