Working on three-phase power and don't want to touch any live wires?
This ETCR1000C phase rotation tester is your new best friend.
It's a non-contact clamp-type detector that just clips onto the insulation of your three-phase lines—no need to strip wires or touch exposed conductors.
It covers AC voltage from 70 to 1000V at 40-65Hz, and handles wires up to 16mm in diameter.



Beyond phase detection, it also does live wire identification, simple power checks, and even finds breakpoints in both AC and DC lines.
Runs on two AA batteries (included) for up to 70 hours of continuous use.
