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.

    I have just removed a B16 ABB type M.C.B. and reinserted it and the bare copper is now not visible. I did the same with an ABB B6 M.C.B. and pushed it back very firmly and the copper is still showing. You could get a car spark plug feeler gauge in the gap, and touch the live fingers. Perhaps the fingers are a bit longer.
