EICR – CONSUMER UNIT IP PROTECTION

PG
EICR – CONSUMER UNIT IP PROTECTION
The C.U. in question is an old Wylex fuseboard that has, replacement, plug-in MCBs installed, complete with new carriers.
There is no covering lid. This was, presumably disposed of when the fuses were replaced.
The C.U is mounted near the corner of a wall such that the board can be seen end-on. The side view of the replacement MCB and carrier reveals a very narrow gap between carrier and base of the MCB such that the (live) MCB brass plug-in connections can be seen. The gap is about 15mm long and less than 1mm wide. Probably better than IP4X.
This is better than the specified IP2X minimum but could be deemed a danger because it would be unexpected rather than other applications with open electrical connections – like a lamp holder.
Forum Members comments would be appreciated

    The issue is can the MCBs be removed without the use of a tool? If a cover is in place, presumably a screwdriver is required.


    Thanks Chris. My issue was seen as more to do with enclosure IP rating but I can say that the old Wylex front cover is secured by screws but the original fuse carrier cover was kept in place by a thumb screw.




    Yes, I did wonder whether the cover had one of those wee knurled knobs. My gut feeling is that these fuse boxes should be C2, but I find it difficult to dismiss C3.


    This argument begs the question, for how long do you say C3? For ever? Or do you at some stage say enough is enough and say C2? In engineering terms, if things have not changed, why change the assessment? Moreover, an inspector is not a policeman. However, should a tenant, or indeed anybody else come to grief, have you got a defence in negligence when (repeated) C3 has been ignored?
