[QUOTE="mk1rob, post: 389920, member: 17694"] Hi guys, I've just rewired a property that has a TNS earthing arrangement. The main earth is attached to the incoming supply cable with a BS 951 Bonding clamp. I was under the impression that this was unacceptable so rang the distributor who said it was ok. I then rang NAPIT who confirmed it was [U]not[/U] ok. However the guy at NAPIT said as long as I get something in writing from the distributor it will be ok. I then rang back the distributor who sent someone out to have a look. He looked at it, wiggled it and said "that's fine as its what they use these days. Its called a Hepworth bond". He has sent me this in writing so I shall put it with the electrical certificate to the customer. Just wondered what your opinion is on all this and am I doing the right thing? Not sure I can twist the distributors arm any more to change it even though I know really its not right. Cheers [/QUOTE]
