Phase rotation test using a Metrel Mi 3155 & A1507 active switch (phase sequence)

Checking phase sequence (rotation) is essential when connecting equipment with 3 phase motors. Gary Hayers demonstrates how to check the phase sequence at the origin of a supply using the Metrel Mi3155 multifunction tester. He then introduces the Metrel A1507 active switch to test phase rotation at a 3 phase socket outlet.
