Trumpy,
over here in england our phase rotation is R - Y - B ( red, yellow, blue 230v per phase).
I have in my toolcase a standard Seaward Brand phase rotation tester, this gives me the phase rotation as you connect to it, Yes you can connect live but i try not to as it is not reccommended within our wiring regs or Health and Safety procedures,
It also doubles up as a phase rotation tester for Star Delta motor installations.
(the main reason i bought it is due to the fact that some of the properties i go to the lables dont always correcpond with the phase rotation !!! )
hope that helps.
Hi to our friend in france as well from all of us on ECN. dont be a stranger.
John
