Removing un-identified cpc's while an installation is energised/inservice must be one of the most pathetic things Iv'e read on this forum.
It's a lighting board and they will be disconnected for seconds.

I am sure you were really just speculating on the idea of disconnecting earths (I hope!) I am also sure you full well know the risks and regs around such a course of action. So I will not impugn your standing in the trade. I think Luciens ideas are doable, I was thinking of a small d.c. voltage (1-2v) or possibly a linesman phone at each end. Not sure how practical that is mind you. I have a cable detector that identifies up to 16 cables at a time but that is for dead circuit sadly. I do think you may find it worthwhile to flag this as a needed part of planned maintenance so when a machine is down you can test ccts for the earth in the future. As identifying correctly ccts is as important as not disconnecting the earth. As it is lighting can you not arrange for out of hours switching off? And are the circuits not placed by numbers on the board like neutral/mcb 1/cpc in 1 terminal etc?
Isolate the board, link cpc to line or neutral at end of circuit. Disconnect all cpcs in the board and assuming parallel paths don't exist you can trace the cpc by a continuity test.
Now now! I know it can get a little "heated" on here sometimes but stick with it and keep calm. There are some valuable insights between the thorns. If you get something a bit wrong (which I have!) and get a new backside ripped dont worry about it. Just make sure you take something of value away with you. They will calm down once they get to know you a bitThat's very clever

I wouldn't say it would be putting the lads life at risk, we work near live circuits all day long it's just one of those environments.
We can make it as safe as possible when doing it and we will identify what we require in very little time resulting in a good job well done at the end of it.
Like you say though everyone has to make choices, I don't think many have died from a single phase 10A circuit that they know is about to have the cpc removed, so what you're getting at I feel is a stretch too far in my opinion.
