How serious is it not to have bonded to the enclosure, emt stubbing up out of the floor into an open-bottom main distribution panel?
There are four four-inch emt pipes with set screw connectors and couplings, each enclosing a parallel set of 750 kcmil aluminum feeders, each including an equipment bonding jumper sized appropriately and each jumper is terminated to a lug on the panel frame. The other end of the emt is connected to the metal frame of the switchgear by means of an emt connector. The pipe run is over a hundred feet.
Thanks
