Tenby earth clamps

Terrifying, when you think that you have to follow manufacturers instructions.




Well, perhaps just mildly annoying.
 
doesn't have to be incorporated into the clamp.. says "at or near" in the regs.. so a seperate label is acceptable..
 
In practice though, the people who are likely to go around disconnecting cables without understanding their purpose are just as likely to ignore any "Do not remove" label.

That describes just about every job I have done where plumbers have re-arranged the pipework that includes the bonding of the incoming water supply :roll:

Exactly! Although sometimes the person doesn't even get as far as seeing the label. A few years ago I went to a nearby house (then friend of a friend) and on finding no continuity to earth at the panel started trying to follow the route of the main earth (TT installation) until it disappeared at a new outer brick shell the owner had built. At that point he remembered that "Oh yes, the cable was in the way, so I chopped it off!"

Mind you, this is a guy who I later discovered had wired a new 9.5kW shower with 2.5 sq. mm cable, and who managed to put a screw right into the middle of the concentric supply cable.
 
French just dont get British Standard do they.

I don't know about that - you see Legrand now own Tenby. BS 951 was probably largely written by Tenby way back in the day.

However, we now have a new version of BS 951 : 2009 and the Legrand clamp 'comforms to it' - now I wonder who made sure that happened :D.
