earth connection issue

[pablod]

hi,

trying to find out who is responsible for the earth connection to the sheath on a property. the electrical supplier is eon. one of their engineers came down and fitted an isolator for me which was great and i asked him to look at it. he had no idea what so ever and told me ukpower networks was resonsible for cables coming in. they say no. they both said i should do it as the electrician. i said not my part of the installation. any ideas to help me out cause going round in circles here

cheers

Clamps (the spring type) are an approved method NOT a BS951 (although these are come across sometimes being used for this purpose) I don`t think soldering or brasing onto a DNO cable is recommended as you don`t have permission to interfere with the DNOs apperatus....and you don`t know how old that cable is and the type of insulation its employing and whether your actions could impair this......because if you did damage that cable....you really would be for the high jump........

Now , ....how are you going to manage damaging that DNO cable using earth braiding and spring clamp wound around the DNO cable?

If this was a case of knowing that the TN-S was a good one, and just the DNO playing silly buggers about making that earth connection off for their customer, then i'd certainly be inclined to to make that earth point in such a manner.... A nice bit of amalgamating tape to seal everything up , and it should be fine!!!

This is the Hepworth clamp http://www.sicame.co.uk/Section8/8.05-8.06.pdf it needs a special tool to apply it.

There is also this Scotchcast Constant Force Springs http://solutions.3m.co.uk/wps/portal/3M/en_GB/ElectricalMkts/ElectricalSupplies/ProductInfo/ECatalogue/ElectricalEarthing/ConstForceSprings/

You may find this is what is fitted as it’s recommended it’s taped over.

Yep, ....it's the ''constant force springs'' that i would be using here, mainly because they are quick and easy to apply, and don't need a tool to maintain the constant force...
