Well, not quite. Leaving aside Andrew's claim to have found RCBOs under
30 quid I am going to quibble with your figures. I've had a tiring day

powering a collection of outside sockets at roughly each corner of the
building, and that would be all that was needed. How much difference
would that be then?
