    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.

    I think im wording it incorrectly.

    Im well aware of the earthing systems, this house is only about 10 yrs old, no earth is taken from the origin so not tns or tnc-s and no earth stake, as i stated.

    So there is no earthing system, hence my question. I have not come across the ELCB, i am qualified yes, about two yrs so i cant of come across everytjhing already could i?

    It must be great to 'know it all'

    Its basic stuff pal, it isnt about "knowing it all"

    And yes you should have a earth rod installed/install one, its called a TT system, the overhead lines provide a line and neutral conductor only, you need a earth rod in there

    Phone DNO and find out if they are supplying an earth, if not fit Earth rods. Not that difficult is it?

    Thats all i was asking thanks.

    May sound unusual but i genuinly have never worked in a house on overhead lines, All new build and commercial/ industrial.

    What we were getting at mate is that regardless of whether or not you have worked on it, its basic electrical knowledge, you learn this stuff on day one

    Im well aware of earthing systems etc more than competent, But a little thrown by a house that old having no earth installed. Was only asking for advice, its supposed to be a forum not the Xfactor judging panel!
