When I posted this I didn't expect this much discussion~
Let me ask a couple other questions...
Has anyone seen a Listed method or product, technical reference, specification, engineering drawing, standard, or anything similar that details how to bond together perhaps several hundred individual pieces of siding or roofing such that you have can quantify the fault current carrying capacity? Say you are attempting to bond the siding and roofing of a large wood frame building. How many bonds are required and where do they have to be placed? If you bond only once in the area of the service is that adequate to clear a fault perhaps a couple hundred feet away in perimiter distance? What fault current is the design value? How about the case where it is a preexisting building and you don't know how the siding/roofing sections are joined or fastened?
Just curious.
