Service point in out building

[Frisky182]

Hi there.
My friend is building a new house. He has decided to put service point in and out building next to new house. A duct has been run from out building to house. I will be using 16mm three core to supply house db. I've decided to use rcbo's for circuits in the house. But I am unsure if the cable at the out building side should be rcd after the cut off to supply the house? Any advice would be appreciated.

It's taken me fifty years of saving to get out of the shoe box in the middle of the road.

MP: Shoe box?
TG: Aye.
MP: You were lucky. We lived for three months in a brown paper bag in a septic tank. We used to have to get up at six o'clock in the morning, clean the bag, eat a crust of stale bread, go to work down mill for fourteen hours a day week in-week out. When we got home, out Dad would thrash us to sleep with his belt!
GC: Luxury. We used to have to get out of the lake at three o'clock in the morning, clean the lake, eat a handful of hot gravel, go to work at the mill every day for tuppence a month, come home, and Dad would beat us around the head and neck with a broken bottle, if we were LUCKY!

go for an armoured sub....

I thought they all where armoured with torpedos

I would use 2 core 25mm swa and a separate 16mm earth. Terminated in a metal clad box (or plastic with 32mm knockouts) feed it from a 100A main switch there to an adaptable box (again with 32mm knockouts. And then supply your board as normal with meter tails from the adaptable box.

Or use 3 core swa and leave one core a bit longer so it will go from the earth at source (tns) to a met at the db. Would look something like this in the end.

As it's TN-S you don't need to do ^^^. The Cu Equiv. of the armour should more than meet your adiabatic.

No overload protection for the sub main then?
