Hi, I am new to this forum I'm just after a little advice regarding an EICR I am doing and wondered if somebody could help me.
I am just completing an EICR for a small industrial unit. It has a 4 way 3 phase distribution board, with the old type M5 MCB's. There is an 100A 1361 2b fuse for each phase. 16mm main tails.
There are 4 single phase circuits only, 2 lighting circuits, 1 ring main and 1 water heater. After performing all the tests, Ze, PFC, earth loops, ring finals, all results are fine and within limits.
Because the board is so old, there is no way of adding RCD protection to the socket outlets without adding a new board. I was always under the impression that sockets do not have to be RCD protected if being only used by skilled persons. And that lack of RCD protection would be a C3. Would lack of RCD protection be a C2 or C3 in this case?
Also the mains tails are 16mm2 and the fuses are 100A, would the fuses need to be downgraded to 80A? Obviously at the moment there are only 4 circuits, would it be the future electrician who installs any additional circuits responsibility or should it fail on the EICR as it is?
Many thanks
