Need to do some work on a house, detatched with overhead lines supplying it.
There is a cut out in meter cupboard then tails inside the house to an RCD or ELCB, then into ccu.
There is no earth present just the tails going throught the RCD in the CU.
My question is.. How can i tell what the earthing system is supposed to be? I need to add a garage unit for solar should i earth stake it? i need to add bonding as its non existant so i could also add that to the stake earth but i dont want to add a potential difference between the earths. There is no existing stake.
Could the earth be taken from the neutral in the ccu to act as a PME type system?
Not come across this before so any help much appreciated.
