Hi folks,
I have a 2.5mm^2 ring circuit in my garage, wired off it's own consumer unit. The consumer unit has two MCBs - one for the 2.5mm ring, and one for the lighting circuit.
I wired it all up myself, the unit is fed from a 10mm^2 cable coming from in the house.
I'm fitting a bigger air compressor in the garage and it will potentially pull 30-odd amps on startup, so I don't really want to put it on the 2.5mm ring.
I'm wondering if I should just wire up a single run of 6mm^2 cable off the same breaker as the 2.5mm ring, and stick a 32a commando socket on the end? the 6mm^2 cable has a higher current rating than the 2.5mm ring and seems like it should be enough.
But is it it badly frowned upon to have what is effectively both a ring and a spur coming off one MCB?
Ideally I'd like to avoid changing the consumer unit to one which can take more MCBs, as it would be a pain.... I know I should have fitted a bigger one in the first place!
Thanks,
Rich
