Cross sectional area of a protective conductors

MS01
Can someone give me a some advice on if we have a earth electrode system made up of the structural rebar when using the adiabatic equation to size of the bonding conductor comes out at 300mm. MY questions is does each bond need to be this size or can it be made up via a series of smaller bonds that are equal or exceed the 300mm requirement? My opinion is each bond needs to be this size to deal with the fault current as the direction it will flow is unknown. What are peoples thoughts? I cannot see anything in the regs on this.

    OMS, and Mapj1, where do you learn such in-depth stuff?

     


    If there was a single source that contained all the information that anyone ever wanted to know and anyone could have access to it, you would likely find that some would be better than others in taking it onboard and disseminating it. Maybe it’s just a gift and I suspect both OMS and Mapj1 have it in spades!

    For most folk, not being able to kick a ball like David Beckham ought not to put them off enjoying football, self included.
