hi just a quick question, I’ve been asked to re-test a block of flats which has just had an EICR done. Was and old board etc, had 2 new RCD boards fitted so no issues there! They have now quoted a lot of money to replace a cable which runs under ground (no idea how) in high tuff cable. This has been given a C1 and quote is to dig up the road etc to replace. I can see the previous issue when there was no RCD protection but now there is so I personally don’t see this as a C1 now an RCD for this particular circuit has been fitted, any ideas on this going forward?
