Need to install an outside 32A power supply.
Already have a garage consumer unit in a summer house which is supplied from the house main CU with 6mm2 AWS from a 32A MCB. So that is already in order.
So far I think I need; 4mm2 AWS to run from the GCU to the socket with 32A Isolator and 32A commando socket. The demand at the business end will be 3KW. The cable run will be 12m. All the work will be tested and inspected by a registered sparky after it is done.
Couple of questions:
Should I uprate the main house MCB to 40A or 50A as it is also running additional sockets on the summer house spur?
Could I use a combined 32A socket and switch instead of a seperate isolator and socket as the GCU already has an isolator switch?
