Advice on reduced live-neutral reading

[DPG]

Who fitted the shower? Not the circuit/isolator or anything else, the actual shower

I've asked that twice already, but no answer so far.

Sounds like this is where the issue could be

Sorry, I literally didn't see it, the forum UI/layout is a little busy

If you want a full breakdown: the shower is in an extension built a few years ago, the electrician did all the wiring up to the tail, the builder built the extension, did the plumbing, fitted the shower and connected the tail. The electrician did his checks and signed it all off. The cable run couldn't be any simpler, dedicated 40amp breaker straight up the wall about 3 metres to the DP and the DP a metre to the shower. All 10mm, all without any insulation.

Everything worked just fine and had done since, until it stopped working maybe 1.5 years into the shower life.

So regardless of who, why, what, my question was really a very simple one: could the meter readings be caused by a short/fault in the shower given the verdict was the mains was at fault despite the shower still being directly connected to the terminal block he was testing. Without touching the mains, removing the shower live/neutral/earth from the terminal block the mains reading was back to normal.

Hope this helps?

Responsibility is with whoever made final connections at the shower. The person that tested the supply at the shower has likely got those readings because of a bad connection on the supply to the shower, therefore not their responsibility. I would be looking at whoever made that final connection.
