PSCC on 460V Split Phase Supply

[Blissof89]

Hi all.

Been doing a bit of work on a pub out in the sticks with a 460V split phase Supply. When tried to test phase - phase PSCC my tester didn't play along. I was going to use the double p - n rule of thumb but then I got thinking, does this still apply to a 460v supply?

I'm in Devon, have a split phase supply myself, as have several of my customers. Very common around here, but when I've had occasion to discuss motors, control gear, etc., with reps. and suppliers, they generally didn't know what I was on about.
Measure each phase separately to neutral is what I've always done.
