Meter enclosures

Les Board

I am working on a block of flats with meter enclosures, serving each flat, on the communal landings (open to the elements).  The sub-mains and tails (same wire) appear to be single insulated, enclosed in trunking on the input and conduit on the output.  However the wires in cupboard also have only basic insulation (same wire).  As the cupboard is designed to be opened by the householder (standard triangular key) so they can read the meter.  The meter cupboard therefore appears to comply with Reg 412.2.2 but in practice will be readily accessible to unskilled people.  Would it comply with 526.5 and 521.10.1? Any ideas?

    It is accessible to any member of the public with a key - which excludes toddlers, pets, and casual passers by. It also provides a lot more protection than if it was not there and the meter was screwed to the wall and left out in the rain and to be hit by passing trolleys or prams.

    It does rather fall down the gaps in the rules as a halfway condition - it is not really the "open with a tool" that applies to a chamber with live bus bars, but neither is it open to all.

    In practice the risk is low. Is it regs compliant, probably, more or less.

    Mike.
