Morning Folks
Friend asked me a couple of questions about his place, so property is remote has it's own tranny on a pole outside, I can see the phase and neutral leaving the pole and going into the ground, I can also see an earth cable leaving the case earthing bolt on the tranny and going into the ground. At the house I can see the cable coming in and an earth coming in. I am guessing the earth coming in is the earth from the tranny casing. I that a fair guess? There is a 30mA RCD seperate to the CU, do you think Scot Power fitted this? When I initially saw the RCD I thought it was a TT system but when I looked a little closer at the connections I think it is TVC-S, as the neutral and earth are connected together before the meter, can you confirm or enlighten me. Please see attached images (I hope).
Also and the question I am dreading asking is, he wants to supply a garage 30meters from the house, can he export the earth (aahhhh sorry) or is it a case of terminating the SWA into a plactic JB and then out on 2 tails to the garage CU and earth spike the garage. Garage is block construction with no water or gas pipes going into it.
Thanks in advance Steve
