about grounds… a New Discussion

[Warren Whiteside]

George, one small correction. I didn't post about not taking the ground 
to a sub panel. I have done that here to my shed and also drove a ground 
rod at the shed sub panel which is terminated in the sub panel's 
grounding bar. I think someone else commented about that part. As to 
terminating your #6 solid copper to your panel ground bar: Yes, you must 
do this regardless of your utility having a ground at its transformer 
that should be bonded to their neutral/common wire of a 230VAC single 
phase service. I'm sure as far as grounding might go it is possible to 
get too much of a good thing but over the years I haven't seen this.
