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......

    I don't understand. What has a new boiler got to do with Main Bonding requirements?

    See Part 2 in BS7671.

    No.



     




    We had a question about this matter recently. Re. The need for main bonding if it is not present and a new gas boiler is installed.


    Is this glue electrically conductive or not? At first glance we may assume that copper pipes are electrically continuous but in reality may not be. So some runs of copper pipe may be earthy and assumed to be bonded but due to the insulating properties of the glue, if it is indeed so, may not be bonded.
