250.24(B) specifically states it applies to grounded systems operating at less than 1000 volts. It does not apply in your case. Can you supply a little more info on the system you are dealing with?
Bennie,PGE, SoCal Edison, PP@L, and many other utility companies retain authority on feeders of this voltage. It is a legal liability concern.
