sheds again

[stueyB]

Hi
Sheds again, I\\\'m afraid.
I\\\'m supplying power to a concrete garage. The builders have run the cable underground during the build. It\\\'s only 5m or so from the main CU. I plan to use a small RCD protected CU in the garage to supply a couple of 13A sockets and lighting. What rating does the MCB on the main CU need to be to supply this? Many thanks..Stuey.

How long is a piece of string??

What is your design current for the circuit?

What size and type is your cable?
