Been asked to make previsions for elec shower in a future outbuild in garden of house I am starting to rewire tomorrow.
The house itself will be heated by central heating- all lights led etc just 1x induction hob then a fan oven +MW. so no excessive load in the house.
Head is 100a SP in external meter box- and c/u in house is >3m so will need to fit a switch fuse isolator switch in the external meter box then 25mm 3c swa from box to c/u.
My question is for the outbuilding supply- theres no space in the meter box for a 2nd switch fuse isolator for the outbuilding so will have to come off of an upfront mcb in the house c/u. But if there wanting like a 9kw shower plus a handful of sockets/lights/heater down there- thats looking at 25/35mm 3core at a 35meter run- which i think is pretty excessive.
1)Has anyone ever fitting a shower at such a distance in for example an outbuilding
2)does the isolator for the house >3m swa tails need to be fused or can it just be a 100a dp main switch? (i think the answer to my question is yes as I can't rely on the dnos mains head fuse- but space looks tight and I know them wylex fused isolators are quite bulky!)
