Plastic switch in external meter box

aligarjon
Can i fit a plastic switch fuse such as an 800kmf in the external meter box or does it have to be metal.   I am not interested in the dno view, they always seem to be happy with our switch gear in there around here so long as we leave them enough room.

    You should be, because without a competency certificate signed by a DNO you are not able to work live on their equipment.

    An unauthorised "isolator" is not covered by the suppliers insurance.

    The fitting of an unauthorised "isolator" will loosen the meter tails irrespective of a withdrawn fuse so the meter terminals will have to be checked afterwards. This of course requires seals to be broken and replaced, again only persons with a competency certificate are able to do this.

    Your best course is to request a suppliers isolator via the customer. The suppliers meter operator will attend, fit, and you being there at the same time can reconnect the tails.

    Ascertaining whether a plastic isolator/sw/fuse is allowable under the "wiring regulations" would be futile anyway because that question has been thrown around for years and no one from the "institution has stuck their head above the parapet and given a definitive answer.
