morning everyone a small problem here I'm hoping someone can clear up.
I am in the process of selling my house and got a major player in the gas industry to come and check the boiler and he has also tested the electrics as well.
Upshot is he plugged a meter into a ring circuit a couple of lights flashed and he has told me that the 200ohm reading is not acceptable and has now condemmed the system and put an at risk notice on it.
The test he did was a fault loop impedence test.I have tried searching on the forums for answer but no luck.
For your info I have 6mm earth cables at my consumer unit 6mm going to my gas and water pipes and all the hot and cold taps are connected together with 6mm.the main hydoo cable coming in has an earth strap on which in turn is connected via a terminal block to my consumer unit.
The consumer unit although approx 15 yrs old does have circuit breakers in it and all the wiring in the house is pvc.
Can anyone help me as why it is at risk.I have a martingdale tester and went round all the sockets and everything is fine according to the martingdale.
Thanks
