DNO requirement for protective bonding

lyledunn

It is very common in NI for NIE to refuse connection to a domestic installation unless main protective bonding is in place to the water service pipe, even when it is the blue plastic type. Sparkies have to fit a copper insert in the plastic pipe to install the bonding clamp. 
I cannot imagine why they insist on this, but insist they do! I was wondering if anyone has similar experience in other regions.

    Well, if you can see how connecting a conducting wire to an insulating  plastic pipe filled with drinking water of resistivity perhaps tens of k ohms across the faces of a cm cube is in any way making things safer, let us know;-)

    I think the technical consensus here is that it is nugatory, but sadly required because rues are written for  blind obedience, rather than to guide and educate.

    PS water much more conductive than that is undrinkably brackish.
