Hi.
Just wondering what is a safe MCB rating for the setup I've currently got on my garage.
In house consumer unit is new & currently has a 40A MCB (non-RCD) protecting the 6mm supply to the garage.
In garage, there is a second mini consumer unit (RCD protected) supplying two circuits:
One powers the main ring (on a 32A MCB).
Other supplys a single radial to power my compressor or welder.
(Compressor motor is 17a but specifies being on a 30a circuit.)
At present, the cable between the two CUs is 6mm and approx 6 or 7m long.
My question is, what MCBs would be best in the two CUs?
I'd like a 40a type D in the house and
a 32a type D in the Garage for the radial and
a 32a tybe B in the Garage for the ring circuit
Does this sound feasible on a 6mm cable?
