aland,
hi mate, in regard to using MCB`s as switches, well personally i would not do this and would advise that the installation is fitted with loght switches to turn the lights on or off,
are there emergency lighting fittings on the same lighting circuit?
as the local authority will require that the emergency lighting is connected to the local lighting supply, by switching out the MCB the supply is lost to the emergency lighting,
not a good idea in my book, and we specialise in the license trade.
