I have seen a diagram showing a wire going thru a conduit with the conduit bonded on both sides of the wire(in essence a parallel conductor) A 100a load was on the circuit and 97a was traveling on the conduit and only 3 on the wire.
With this is mind--a simple residential service, rigid nipple thru the wall between the panel and meter socket, since both the service panel and meter socket are bonded to the neutral conductor, will a majority of the current be traveling on the conduit nipple?
Would a bond bushing on each side of the nipple with a conductor connected to the neutral from the bushing increase the skin effect by creating a lower resistance path to the neutral in the panel and metersocket?
I make contractors remove one bond bushing when I see this arrangement, quoting objectionable current (from 250-2? don't have my book in front of me). Am I off base?
