Had what started out as (ended up a cu change )a call out to an RCD tripping as soon as kitchen ring final was switched on.
Kitchen fitters had installed a new 10mm cooker circuit as well as extending the ringmain where do you suppose they installed the ccu ?
Thats right in the garage some 15 meters away from the cooker, as you will see they struggled getting the face plate onto the pattress. To get over the gap they put a wrap of white packing tape around the accessory (I've removed it for the piccy)

The reason the RCD kept tripping, the line conductor legs had been joined correctly (all beit untidy & with a 15amp chock block & red tape) but the new neutral legs go to rcd side neutral terminal & old neutral legs go to non-rcd neutral terminal.
So to get over the problem they banged it on the non rcd side.

The picture is how I found the cu all open but no cover & not isolated.
No certs from fitters & not a fitter insight, they are due back in the morning to complete the tiling.
How chuffed will they be to find I've pulled tiles off (as directed by customer)to fit a ccu in the kitchen & they wont be getting the full payday they were expecting, as the customer is going to hold back the
