So we"re depending on the Screw supporting the Panel to bond the steel???
250.8 List Permitted Methods for grounding & bonding. I don't see Panel screws on there??
Even the service must be Bonded to the Structureal steel .
2008 Handbook page 241 Right after 250.104 (C) Explaination:
250.104(C) Requires exposed metal building framing work that is NOT intentionally OR inherently grounded to be Bonded to the service equipment or grounding Electroid syastem . This requirement applies to ALL metal framework not only to steel framework.
