Basic insulation exposed in electrical outdoor meter box.

AMK

There’s debate about exposed basic insulation in meter cupboards being satisfactory or not? Industry guidance (WRAG) say it’s satisfactory if the door’s in good shape, what’s people views on this ?

Parents

  • It seems absurd to me to have exposed basic insulation where it's fully expected that unskilled unsupervised people will, and indeed by design, should, have access (since they're expected to able to read the meter). In this case the triangular key does nothing to restrict access, since everyone in the household will have access to it. Unlike say sockets or switches that could be opened by a common or garden screwdriver, there isn't even the common sense restriction that it's something not normally to be opened by the unwary.

    It's like saying bare conductors are satisfactory in an office, or broom cupboard, if the door needs a key to open it.

    Yet by the wording of the regs, both would seem to comply. It's a strange world.

    Broadgage and Andy sum it up.

    "Key or tool" - the fact that they are readily available hardly meets the intention that access should be restricted to more than ordinary persons.

    I am tired, so I am not going to plough through the Big Brown Book, but C3 for me. Poor workmanship!!!

    How so? the conductors are not "bare" in this case. 

    However, just to be 100 % clear, bare conductors in enclosures of equipment to designated standards, for example, are acceptable ... provided the enclosure provides an appropriate IP rating, and the conductors are appropriately separated, it could well even be sufficient for double or reinforced insulation !
