Should the sheet metal (steel) siding and roofing of a post frame building be grounded?
If so should it be bonded to the ground bar or ground rod of the building's electrical panel?
My pole building sheet metal does not contact the earth. The metal is painted and may have electrical bonding between the panels either at a common fastener or bare spots in the finish.(or maybe not, who knows)
Also the electrical panel is installed on wood framing with no fasteners touching the metal siding. The electrical panel ground bar is bonded to ground rods but the bond is insulated from the metal siding.
I have looked at similar buildings(wood frame) in my area and see no evidence of grounding of the sheet metal except by accidental contact.
This building is used as a machine shop/storage building, no farm animals.
Is there a right way? or a better way? or does it make any difference?
Thanks, Borderbuster
