Non combustible switchgear

[WallaceP]

hey guys, I had a quick search but couldn’t find any posts about this.
I recently done an inspection on a domestic property and found the electrical meter was outside in a service cabinet and the fuseboard was inside more than 5m away. I recommended installed a fused disconnector at the meter to comply with regulations and also for convenience if the fuseboard had to be isolated.
I would say this should be non combustible but I still see a lot of the plastic styles of these switches available. Such as LEMSF100.
Is it possible for this to be installed as it is outside the home? I think I would rather install a metal one anyway but curious to hear your opinion on the matter

No they’re not exclusive, anything can comply with more than one Standard.
However, in order to comply with BS7671, the Switchfuse must comply with the Standard which relates to Switchfuses, not the one which relates to Consumer Units.

That was pretty tame. In a domestic setting, in a scenario where a A3 CU is installed, doesn’t make sense to me that if a switch fuse was installed next to it, that could have a plastic enclosure, and comply.

Suppose any guidance, might be again that the designer would have to carry out that risk assessment or judgement.
