I've got another EICR to do on a complex next week and do any remedial work necessary. * flats in 2 blocks and some are fed in 16mm T&E and other are fed in single tails/earth for whatever reason. The T&E's are fed via fused isolators but the tails come straight from the meter and then through a DP isolator switch and then onto the flats. Firstly there is no overload protection on the tails at all, just an isolator and secondly some of these tails go all the way to the second floor and I'm concerned about the cables runs, you can see from one mains unit they drill straight through the wall and are obviously buried in the plaster in the middle of the landing side, probably not even in any sort of zone,even more dangerous than burying a t&e cable. So, if I replace the isolators with fused ones am I then liable for the buried tails in the wall and need to do something about it? The company don't want an EICR with any C1 or C2's. C3's are permissible if its just a technical non compliance, the only way I can see is fused isolators and new SWA submains but this would obviously cost thousands and as usual they are tight fisted.
