AAaaahhhhh. The Bonding Question Again.

Zoomup
Do we main bond up an installation if a new gas boiler is to be installed when the old one is removed?


What are extraneous-conductive-parts, and what are not?


Now, to put a spanner into the works, do any issues arise if the copper pipes are "bonded" with solderless copper bonding?


Otto von Guericke would have known this for sure.


Over to you?


Look......

    The copper pipes may be considered to be extraneous-conductive-parts if they are buried in the floor though. So there may be a section of copper pipe main bonded at the point of entry into the building,



    Yes.


    then an electrically insulated section by insulating glue, then a real earthy section, all simultaneously accessible.


    That doesn't matter. 


    Not good. There could be dangerous Voltages between copper pipe sections, those P.M.E. bonded and those with true earthy connections.



    But the true earthy ones should be bonded so at the same potential.


     




    No, the true earthy sections may not be bonded if the copper pipe has glued joints where they are electrically insulating by virtue of the new copper glue (Super Power Solderless Copper Bonding), if it not electrically conducting.
