Having just looked it up at http://www.nfpa.org/ The latest code is the
2002, with the 2005 due to be issued in Sept 2004. Be aware that many
jurisidications adopt some other version as the "official code" for their
municipality, so you might not actually be subject to the 2002 code in your
location, in a "legal requirement for a building permit" sense.
However, if it came to a sticky issue, one would be expected to be aware of
what's in the latest code (part of that "responsible professional" thing)
and whether it was significant.. that is, in civil proceedings, you can be
held to a higher standard than simply "what's in the law".. The "law"
determines whether there's criminal liability or if it's just going to be a
civil "you gotta pay for what you done wrong" sort of thing...
Hey folks.. there's a lot more to being "in the business" these days than
just hanging up the shingle and saying you're open for business. When
things go wrong, the net is cast very, very wide to attempt to "point the
finger" at someone else, or at least to get some other "interested parties"
involved in the process.
I don't recall any significant differences in recent revisions of the code
with respect to grounding, though...
