Bonding 18th edition ?

Hi guys with the new rules with main bonding in the 18th edition how are you all implementing this.


So is it now a complete no go with the mains bonding unless it has a earth potential once its entered the house ? or is it just optional ?

  • I think the only new 'rule' is the sentence in 411.3.1.2 which is a long-overdue correction of the long-standing error in 544.1.2.


    Unfortunately, the error in 544.1.2 has not been removed.




    Anyway - neither of these affects the correct application of main bonding which, like the physics, has not changed.


    Namely, that main bonding is applied to extraneous-conductive-parts and not applied to parts which are not e-c-ps..
