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.

    An independent stand-alone isolator, or alternatively an isolating switch/fuse or isolating fuse/switch is not "similar switchgear"

    I agree that a simple isolator or a single RCD in an enclosure doesn't constitute similar switchgear since neither meet the definition of a distribution board. I'm having difficulty however putting a switchfuse in the same category according to BS 7671's definitions.


    What is the essential difference between a switchfuse and a 1-way consumer unit?
