Quality one today.
Went to move shower isolator for my brother as hes doing a new bathroom. Ends up being a pig of a job as bathroom is in an extension, with a flat roof and the bathroom ceiling is timber clad.
Goes down stairs looks at CU and right away see this huge old iron service head. Then i see the nice new 16 mm earth along side the new tails, but then can't seem to see the earth connected to head or supply cable.
Ze tests at 13.9 ohms. Quality I think.
Out comes the circ saw and I take up the boards around the service to see if its and old 951 clamp hidden away, but no, nothing. So got the work light under the boards to be greeted by this beauty!
951 clamp onto the lead water service in the floor void. This being used as the earth connection.
They spent 3k on a rewire earlier this year. Not a single cable entering the CU is new, not only because they're all the old colours, but they're all still painted up in emulsion paint. Then I find no bonding to either gas or water and only half the new CU has RCD protection.
Had DNO out who confirmed that there had never been an earth supplied since day one, yet no earth rod insight. Good thing though DNO are back out tomorrow to sort an earth and change service head.
Since getting home tonight, my brother has gone back to update the customer regards his so called rewire and got to speak to the spark who did it. He blamed the testing on another guy who tested it all, confirmed that because there was no supplied earth they had used the water supply and when asked what readings he got for their Ze, he started stuttering and all of a sudden was lost for words.
This pics also makes be wonder. Its a dual RCD chint CU, but in place of the first RCD their seems to be a 63 amp C typre DP MCB instead. God only knows what his plan here was.
