Earthing conductor connection to tn-s

Can anybody tell me the correct clamp/method to use to connect new 16mm main eathing conductor to the suppliers metal sheath.

Thanks

the correct method is to contact the DNO and ask them to connect it.

It is their equipment, and no one else should be touching it.

thanks RF, I contacted DNO who said i should get on with it, so is there an approved method as the existing 6mm is affixed using a 951 clamp

Coil springs and braided earth wire onto the sheath to the MET, and then connect your 16.0mm² to there.

Ring the DNO back, and tell them that it is their responsibility, not yours, and ask them if they are really asking you to commit a criminal act?

Afaict it's not a criminal act if you have thier permission, I would certainly want a recording of the call though.
