Running a separate ground is ok, BUT it must follow the same path as the
cable.

Thanks very much bud..
So, would we be able to use a separate ground from main to subpanel and
still use the wire? It just wouldnt be routed the same way, as the
4-4-4 is.
Thanks

Hi everyone,
Sorry to resurect an old thread, but I had to relate this.
We had an electrician out. He told us this wire was likely for a
planned addition and this would be for a feeder to the addition's sub
panel. Confused, I said to him "but we have only 3 conductors, and no
ground?" To this he replied:

"It is common practice to ground the sub panel AT the subpanel, there
is no need to run a ground from the main breaker box. This also saves
copper."

So ... Is this indeed common practice/code?

Not grounding to the originating panel is only permitted for a separate
building (like a garage). And probably won't be allowed for separate
buildings in the 2008 NEC.
