I'm looking at the options for customer who has no CPC on lights as is quite common. I know the ESC "good practice guide" - and that all makes good sense.
However most light switches with exposed screws into metal back boxes (where metal box is unearthed because no CPC), would therefore be class 1. - I am looking here at a standard light switch directly outside the airing cupboard door (metal tank therein, touchy both maybe.. ).
Q) Might the ones with small plastic plugs (eg LAP 2-Gang 2-Way 10AX Light Switch White | Screwfix.com) be classified as Class 2 for the point of this exercise and be a suitable swap? They are not advertised as class 2, probably uncertified as that, but a safer bet than ones with exposed screw heads? (at least till someone looses the weeny button thingy) .
A related question. I guess BC lampholders are intrinsically class 1, but as they are right up there in the ceiling, what's the likelihood of Mrs Jones touching both the metal surround of her light holder (just as it fails L-E), and her radiator? If I assume normal length arms, I think we are safe here.. Where does one draw the line?
