Dear All
A mate of mine recently asked me to look at his installation. It has been wired to the 17th edition and all looks kosher, but when I carried out some testing I discovered that it had High impedance values. I disconnected the Main earth that had been connected to an earth clamp, attached to the armouring of the Supply Authority cable (old type armoured covered in hessian and bitumen). Took a reading from this clamp, this gave me a reading of 4.29 ohms taken with a Fluke 1653. The type of supply is TNS.
My questions are these:
1. Is it the responsibility of the Customer or the Supply authority to provide an Earth?
2. Is there a charge for the customer if they request a TNC-S supply (PME) instead of a TNS, seeing there is no Earth provided.

Kind Regards

Steve F
