Guys,
Thanks for your input.
And also welcome to our new friend-"FrenchElectrician".
John, I thought that the UK system used 240/
415V(no Neutral).
Sorry to pin-prick!.
I have a set of 11kV Phase Rotation Sticks,
I've only used them 3 or 4 times, but at these voltages, you need something to keep you away from the buzzing ergs. [Linked Image]
