    Certainly a MCB rather than an RCBO seems better.

    Not sure about putting the Earth conductor through a different hole in the steel box to to the meter tails (obviously the thermal effects would be minimal, but I can't help wondering about the extra impedance for the spikes we're trying to divert), nor about the loss of a single main switch for the installation.
