Rather general questions. And a rather specific replies (at least for what would apply to my employer's stuff). Also note that there is a renown engineer at Microsoft that is quite intimate with the NEC - perhaps he will comment.
- allowed ground-fault current different. -allowed bonding resistance to the GEC different. - GFI/AFCI interrupt implementation are different. - 7671 requires many other standards. The NFPA can (theoretically) be used without any external references. - mutual recognition is impractical. There are no assessment product standards that can be used to list electrical building materials to both 7671 and NFPA code. - U.S. code can be modified by municipal or state or county or space aliens. 7671 is a national-only, centrally-controlled document.

Hope to hear from you soon. Thank you.
