Voltage on CPC

Cheaper all round, to just buy a £10-15 analogue meter!! lol!!

In other words, always carry a cheap analogue voltmeter in your test kit, to check any suspected phantom voltage!!

Above my pay grade. But going back to my original post, this came to my attention because my Megger 1730 aborted ZS/RCD test because it sensed a 'high touch voltage' at that lighting point, but not at an adjacent ceiling rose (on the same circuit). So is this touch voltage, a phantom voltage, I can't see that?

Voltage could be caused by loose neutral but you need to carry out tests as previously mentioned

not without being there.

first test i would do is get a wander lead from the suspect cpc/s and measure ohms back to the MET.

Totally agree - This is almost certainly non-continuous cpc subject to induced voltages
