Phase sequence testing is a crucial step in connecting a three‑phase load to an electrical system. For example, improper connection of three‑phase motors may lead to reverse rotation, resulting in damage to equipment powered by the motor. Extech testers can be used to assure proper and safe connection of electrical equipment on three‑phase systems.
