Hi all
Now being upfront I am not a sparks.
I am about to have some work done by a friend (certified) and as he is doing me a favour I want to as much ground work and speccing up as I can.
So heres the situation.
we have a summer house at the end of the garden which is being fed by swa from a 32a rcb in the house.
This goes to a 2 way garage cu to feed the power and lights. All works well but if some thing trips on the circuit it trips the main rcd in the house.
I am building an office between the office and the house.
I have inherited some 2.5mm swa so my idea was to swap out the 2 way cu in the summerhouse and fit a 4way cu with a 20a rcbo to feed the office.
Now the office has a shed attached to each side and I would like power and lights to these as well.
My original idea was to use the old 2 way cu to feed power and lights , but I think it would be safer to have a separate breaker for the sheds and one for the office.
There wont be a huge load in the office, couple of laptops, router etc , an echo and a mini fridge. Again not much in the shed maybe a fridge and then the odd use of power tool and lawnmower etc?
Now bearing in mind the feed for both i protected by the 20a rcbo is there any point in using individual rcbo?
What I am hoping to achieve is protection such that if do something stupid in the shed and it trips then it doesnt trip the office.
I dont mind paying for the rcbo but if theres no point then I wont
Thanks all
