ATOPLEE 3 Phase Sequence Presence Rotation Tester Indicator Detector Meter with LED and Buzzer 60V~600V (3 Phase AC)

Excellent bit of kit used it loads for matching phase rotation on generator supplies worth the money

As I'm in the UK and a bit rusty on three-phase installations, I put together a little aide-memoir to understand the different phase designations and how the meter leads need to be connected up.UK standard phase rotation is anti-clockwise (RYB), referred to as CCW on meter.Otherwise, the meter helped locate a dead phase (loose connection).

Very affordable compared to the professional level meters out there but was only required to ascertain the correct polarity on the incoming supply to a test panel. This simple device has now confirmed that the prewired Ceeform sockets had been incorrectly wired and identified on numerous 5-core 3P, N & E HO7RNF extension leads for 42kW mobile heaters. It's saved a lot of wasted time when delivering equipment to temporary sites knowing that the equipment was delivered with the correct phase rotation from end-to end.
