Reliable Three Phase Wiring Tester

The TESCO Phase Sequence Indicator 500 is a compact handheld device designed to make phase rotation testing simple, fast, and reliable. Built in the USA, this rugged tester requires no switches, no batteries, and no calibration. Just connect and read.

When voltages are symmetrical, only one lamp will glow, instantly confirming the wiring sequence. If voltages are unsymmetrical such as two phases with a neutral, the brighter lamp identifies the correct phase order.
