My intuition says no, there is no difference, other than ground bus bars are bonded to the grounding reference.

As a followup, can any busbar be used as a current-carrying conductor by using insulated standoffs? Thank you.

  • \$\begingroup\$ The only difference in the bars themselves that I can think of is that bare copper or aluminum may be more acceptable for a grounding bar than a current-carrying one. Insulated mounting is not necessarily the only mounting difference, Current-carrying bus bars need to be mounted and braced to avoid contacting each other or the supporting structure in the event of a high surge of current that might be experienced during a serious fault condition. \$\endgroup\$ – Charles Cowie Mar 19 at 11:01
