    Hi all,

    Can anyone point me in the direction of any regs pertaining to the earth terminal connection on a TNS supply.

    I have read that there should be a earth wire or terminal soldered onto the lead sheath (provided by the DNO).

    I have done a few jobs where either there is a BS951 clamp or a form of hybrid BS951 clamp that has been soldered on (looks a bit DIY).

    Are there any regs regarding the type of connection/clamp that is permitted ?

    Upto now I have spiked where I have any doubt. But I would like to see some official reg.

    Cheers,

    J.

    I think it has to sate it on the clamp box now as well that it is not suitable for lead sheath.

    just looking at a box of earth clamps and it states :

    "not intended for use on the sheath or armour of a cable

    Such misuse of a clamp is a departure from Regulation

    Yeah Chubbs but we aren't talking regs here. this is in DNO territory so they make up their own and have been since NICEIC was a baby.

    As has been pointed out by Chubbs Tenby T14 clamps to BS 951 (all) are NOT allowed o be used as TN-S clamps. On eof my local DNO's (EDF) will go 'mental' if they see T14's being used for such purposes an quite right too.

    every single time
