Cable size

[wheelycat]

hi there
I want to run a cable to the garage to a seperate CU so I can run a ring main for power, washing machine,dryer,freezer workshop excetra. Lighting for outside and power for summer house and greenhouse all on seperate MCBs with the correct rating. I have a split load CU in the bungalow and I will run this from the RCD side. Would a raidial cable of approx 10mx6mm suffice or would it need a return as if a ring circuit or possibley would 4.5mm cable be okay .

would 4.5mm cable

try and find it

You'd probably be better running a 10mm SWA ( armoured ) cable from your Consumer unit. feed it from a 40A MCB on the NON RCD side and connect to a Consumer Unit in the garage with a 30ma RCD in the Garage.
From there you can either do a 2.5mm ring main for sockets or a 4mm Radial.
Lighting on 1/1.5mm
4.5mm cable doesn't exist
Hope this helps

Thank you BigJon
Would it require armoured cable as the garage is only 1m away and I could place it in a conduit above head hight, perhaps Mr Breezer you could spend your time giving people more usefull advice or perhaps your not up to it I did make a mistake and incorrectly wrote 4.5mm but whats a mm between friends

A conduit should be fine with 10mm twin + earth, although it should be 3m high but as long as its well above head height I dont see a problem as its not a busy public walkway although a governing body may think otherwise.
