    As above, what is the consensus here. If a switch fuse is fitted in an external meter cupboard, does this count as a similar assembly and have to be non combustible? I've had to do a couple recently and have used the Wylex A3 unit, which is a really nice bit of kit, but its a bit of a beast...

    Nominal Voltage

    Why has nominal voltage gone from 250Volts back in the good old days, to 240Volts, several years ago, to 230Volts more recently? What is the legal max and min tolerance in the 230Volt level?
