Phase sequence testing is crucial for many three-phase loads. Improperly connected motors can result in reverse rotation, which can damage the equipment powered by the motor. Ensure electrical equipment is correctly and safely connected with Amprobe's PRM-4 Phase Sequence and Motor Rotation Tester.

The PRM-4 comes with test leads (red, green, and blue), alligator clips (TL-PRM-4), one (1) 9 V battery, user's manual, and a soft vinyl case.
