Alwite lads,

Replacing a consumer unit today in ex council house. Got Earth fault loop of 537 Ohms, after playing around and finding the electrode which was a steel pipe I replaced the Eath cable from 10mm to 16mm and drove a 1.2 mtr copper rod in got a value of 410 Ohms. Then drove another in the front garden lawn dropped to 360, stuck another in got 300, stuck another in got 200, stuck another in got 130Ohm.
So i have got 5 rods in the ground at the moment. Obviously the customer is not to keen to have so many inspection pits in there frount garden .

Any Ideas would be very much appriciated, or am I missing something
incoming supply is over head


Cheers


Ty

Oh, I forgot to say, drive it down with a SDS on roto-stop and a socket attatchment, its effortless.
Well done on that reading, your hard work has paid off!
