Came across this recent CU change yesterday while quoting to replace some Storage Heaters.
The builder had replaced the original Main CU and seperate Economy7 CU with the unit pictured below.
He crammed both sets of tails into the mainswitch by cutting some cores off of each tail and put a strip of wood between the tails as extra insulation.
He installed the 1mm lighting circuit on a 20A MCB, the 6mm Cooker circuit on a 63A MCB and put 2 seperate ring circuits on 1 32A MCB.
Obviously no testing or certificates, he even mounted the new CU lower than the old ones so that now the door hit it when fully opened.
I advised the customer to contact LABC and Trading Standards and wait to see any results.
I have now replaced this with 2 seperate CU's, fully tested and certificated ( 2 IR faults found ) .
The Cowboy's skills are not limited to electrics as he also stuck some ceramic floor tiles down in the bathroom and kitchen with NO NAILS which have now started to crack and the laminate floor in the bedroom has been laid so tight to the wall that it is now rising in the middle.
