RCD tripping whenever fuseboard is turned on even if all fuses off

Anonymous user 23/02/2024 - 3.24 PM

I have a chalet and the site fitted an RCD between the supply and the meter earlier this year. I have now arrived on site and I cannot get the RCD to not trip. I have turned everything off and unplugged so there is no load on the system and it still trips the instant I turn it on. I have even removed all the fuses in the fusebox and it still trips as soon as the RCD is turned on. Is it likely a problem with the very old fusebox, with fuse wire, or does it sound like the RCD was fitted incorrectly? I have posted a job for a sparky to come and investigate and change the fusebox to a modern one which I had planned to do this year anyway.

Are you a tradesperson and able to answer this question?

Why did it get fitted between the supply & the meter? Usually between the meter and consumer unit.

It appears you might have a neutral to earth short on one of your circuits and it would only be detected by fitting an RCD.This would be complicated to find as a diy’r recommend bringing in a time served electrician to sort

You most likely have an earth-neutral fault in your property-easy enough job to identify where the fault lies
