Hi there, your thoughts on an EICR if been asked to carry out. From the picture attached its a bit of a mess, but to explain its a 3 phase supply which looks like used to be a shared premies but now a sports club and a doctors surgery that im in.
What the installation im looking at is on a single phase of the supply and when installed about 6 years ago the tails terminate into a henley block from the meter and then feed 5 consumer units.
One of the CU has a faulty main RCCB, so my question is obviously to change this I need to cut and pull the main fuse which of course is supposed to be not allowed.
I know how its been installed is extremly bad practice as nothing can be isolated safely which im putting in the report that but whos responsibilty is it, mine or the DNO to get a main isolater fitted for this installation?
Many thanks.
