First of all hello - this is my first post afterall.
Now my question:
I need to install sockets and lights in my new garage - it is timber with a real tile roof (no change of water ingress) and there is no water supply to the garage. I will need a couple of lighting circuits so I don't need to light the whole thing all the time. I need loads of sockets - but will probably use a MIG welder, heater, radio all at once (substitute MIG welder for any typical hand held power tool for most of the time).
However, my house CU is full.
There is a MCB (40A) in the house CU feeding my shed which has its own CU with a 6A light MCB and 32A socket MCB. The shed power comes from the house CU via an old shower cable then SWA (3 core 4mm) underground. There is a RCD at the end of the SWA before it goes into the shed CU.
What is best for getting power to my garage?
Adding a MCB to the shed CU? and running SWA to a garage CU?
As the existing SWA to the shed is only 4mm is that big enough?
I'm concerned that the old shower cable is too small - how can I tell? It's the same size as my cooker cable.
By the way the shower cable setup to the shed was done by previous owner or an electrician they employed not me.
Any advice greatly appreciated.
Mike
