neutral bonding jumper
neutral bonding jumper
(OP)
what is the minimum size for a bonding jumper from the secondary side of a Y transformer to 4-wire 480V switchgear - conductors are rated for 2500A? The loads are all three phase balanced. Also, should the size of the jumper from the transformer secondard neutral to ground be the same size as the jumper to the switchgear?
