I am in agreement with iwires post of 06-14-2003-08:13AM.

It is apparent that many electrical people, including electrical inspectors, do not know the various terminal bars in Service Equipment, or Panelboards supplied by Feeders.

Some seem to know when it is in diagram(s) of circuit(s) but when looking into a panelboard full of wiring they are "lost" as to the identification of the various terminal bars.
