400v at Lights

I've not been sent back to it, other guy was sent this morning to find out what the deal is so I'm just waiting on the phone call!

Turned out there was an absolutely spectacular joint buried in a ceiling that had been lowered and then had a suspended ceiling hanging from it... Neutral connection had frittered away causing the 400v at lights, rewired from the main iso up to the iso in the motor room with a direct cable to replace said joint and voilà, standard readings across all phases etc.

Bit of a head pickler when looking for the fault originally but i'm glad I had it, learned from it!

Glad you got it sorted out eventually and thanks for letting us know what the problem was, it's always nice to get some follow-up info.
