hi
i want to run power to my parents summer house. There is an enclosure on the frame work at the end of the pergola which is fed by 2.5mm SWA which was installed when his workshop was built. First question is is 2.5mm man enough to run workshop?? He runs saws, drills, planers etc but never all at once plus lighting!!
With regard to the cable supplying the enclosure, is it ok to fit an RCD at the junction and carry on the run (approx 20m) under ground and up into the summer house in 2.5?? i wanted to use 4mm and know that you need protection where the cable size changes.
It will be supplying a small Hager CU with 63A main switch, 63ARCD, 6amp MCB for lights, and 16 or 20amp MCB for sockets.
many thanks
