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.

    It is not manufactured as an assembly to BS EN 61439-3 as it is not a consumer unit

    Interesting - I thought most would have considered a switchfuse as coming under the heading of 'similar swicthgear' - being pretty much identical in function to a 1-way CU (DP incomer, feeding one OPD, suitable for use at the origin of an installation and so on).


    So if it doesn't comply with BS EN 61439-3 isn't that technically another contravention of 421.1.201 - which not only asks for consumer units and similar switchgear in domestic premises to have non-combustible enclosures but for them to comply with BS EN 61439-3 as well.


    Steel versions are still readily available - e.g. https://www.screwfix.com/p/wylex-100a-domestic-switched-fused-unit/5290j

    that Wylex one for example appears to meet the requirements of  BS EN 61439-3 as well as 60947-3 according to https://www.electrium.co.uk/media/20151123152755_0_Wylex Domestic Switch Fuse Unit.pdf.
