Earthing Conductor clamp

[orbital]

I know that BS 951 clamps are not correct for earthing connections to incoming supply sheath.

What about this clamp, is this OK

Cheers

That is a 951 clamp just a double one.

Thanks, I was a little unsure.

What is the best way to rectify this.

Its not allowed/advisable to clamp onto this cable, so is it a DNO job?

Generally dno will no alter them, in my area edf which was eastern a lot were put on by them in the first place. As long as loop is ok I would just leave it a note it on your certificate.

Its a DNO job, by the looks of it thats a metal cutout which the DNO are changing on a roll basis, so a quick call to get a cutout change should rectify the earthing

Sure thats a bakelite one.

You could be right but the ones I have seen in my area are mostly mettalic, though I have seen the bakolite versions.

Not supposed to fit earth clamps to DNO supply cables , it is reckoned they can crush the lead sheath plus you are not supposed to interfere with their equipment.

I know there are millions of them around , the network companies are totally lax in supplying earth terminals , every one quick to force contractors into joining scam providers and shell out for exam upgrades etc, but millions of homes without a decent earth connection.

BS951 is not suitable for connecting to cable anyway whether you have permission to do it or not.

See this all the time round my way. Usually change it to TT and run a 10mm to the sheath to bond it.

So how do you bond it to the sheath?
