Wylex 100A dp isolators in plastic enclosures.

Just wondered  why these are not classed as "similar switchgear" to consumer units etc which are supposed to be in

non flammable enclosures in domestics.

    Also, such switches are often installed ahead of a consumer unit that incorporates RCD protection and is connected to a TT supply. Requiring a metallic case would introduce new risks. If the phase conductor contacted the metallic case, then the whole installation would have virtually line voltage on all earthed or bonded parts.
