Question about a thread from another forum

[Marc M]

I've seen many discussions on this subject in general, but have one more (hopefully final) question.... If there is a sub-panel in a remote building, where there is no other conducting path connecting the two, a 3-wire service was acceptable under earlier code editions. My question is - if all the conditions are present to qualify for that exception, should a ground rod be driven at the remote location and be connected to the neutral / ground bus in the sub-panel? TIA
All of the answers were yes.
My question is, at the end of the thread he said "connect the neutral /ground bus to a driven rod", in this exception are they allowed to be connected together? Just a little confused.
Thanks

Hi Marc,

Under the conditions given in that thread, the answer would be yes, that would be required (see my post on that thread).

Not allowed anymore (since the 2008 NEC) but was for earlier editions.

will do, thanks...
