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 ?

  • How many of use would be content with exposed live parts in a meter box? (say a henley block with the cover absent or just 1" of bare copper showing at terminals)?

    If we accept that the meter box is an electrical enclosure, then it follow that the enclosure provides basic protection (from direct contact) as well as fault protection (that's what 416 says) therefore we must accept exposed live parts inside a undamaged meter box without code or comment - as it would comply completely with BS 7671 requirements.

    If however you think that point of view reduces to absurdity, I think we do well to question the initial assumption.
