    Hello All,

    We look after an old mill/factory and ive just been given the test remedials list another company did.
    A bit part of it is bonding to steelworks and big gas pipework.

    How do i determine size needed?
    Is there a formula/table to work off?

    It depends on the nature of the incoming supply and any special requirements from the DNO, what is the earthing system?

    I’m assuming it’s an LV intake here?

    Have a butchers at the section in Bs7671 confusingly titled 'Main Bonding Conductors'. Might just tell you what you need to know!

    Don’t guess as main bonding requirements are governed by more than just a table.

    For a start what is the earthing system and size of the earthing conductor?
