On the same theme as above you may need to bear in mind is
descrimination of the protective devices. You want to try and ensure
that a trip on the power circuit in the garrage only takes out the
local MCB and not the upstream one in the main CU as well hence losing
your lights.


That would probably require the feed to be via a separate switch-fuse
rather than an MCB in the CU - certainly a better arrangement, but does
involve teeing in to the meter tails with a service connector block.

Hager do a MCB sized HRC fuse carrier, which can solve that problem in
many cases.... although having just typed that, I remembered that
Roger's CU ain't a DIN rail jobbie anyway, so this is of little
practical use to him! ;-)
