OK, sorry, did not see that. This thread is getting large and off topic a bit.

So your pulling #4 for a 70 amp feeder? This will need a min of #8 EGC.

I cannot find where is was suggested to not use an EGC and only use a ground rod, too much to review I guess.

It does not matter, the good thing is your persistent with chasing me down and asking questions.

With using a 4 wire feeder that includes an EGC, a ground rod is not needed at the subpanel.

While a 3 wire feeder with ground rod is now allowed, it will be discontinued in the next code edition 2008. So may as well be ahead of the code, int his respect.

Add your answer here.
