Dunno where the end of this thread has gone. I'm sure there was more conversation had last night lol!!
Right.....I have come to a decision! Flukey it looks like your advice regarding using the house earth is not only sound but expressed by quite a few people. That said I have still not been able to to find anything in the red book to substantiate or disprove it....yet!! lol!
I have a TN-S supply and there are no extraneous conductive parts in the shed. The SWA in place is 3 core 6mm and the length of the cable is not excessive (30m max). At the mo the only earth is one of the cores so I think I will also use the armour (which has never been terminated properly at either end - just shoved into both CUs)..... and terminate it at each end properly obviously.
The shed CU looks pretty sound. 63A main switch, 30mA RCD protecting 32A final ring and 6A lighting circuits. At the house end its not quite so pretty . The shed supply is dropped straight into a 20A breaker which is also being used by the radial supplying the immersion (and god only knows what else until I ripped it all out the other day.) As I am changing the CU its not an issue for now.
The new CU at the house is gonna be a split board, double RCD so I am not gonna feed the shed from it as I dont want RCDs tripping all over the place in case of a fault. So I am gonna split the meter tails in a Henley Block and feed a set of tails into a little 2 way CU in the house with a 63A main switch and just a 40A type B breaker supplying the shed. I'll then run an earthing conductor from the main earth terminal in the house to the little CU.
What do ya reckon?......I'll get my coat! lol
