Thank you all for your responses. As usual they were very informative and right on the mark. I was told (don't use AC so did not give it a thought) that the jacket of AC was not designed to be a grounding path. So of course I got my confused on the uses of the bonding issue. I am not an AC fan and will use metal pipe or MC where necessary.
Should have checked the AC art. myself.
Can now put the orginal question in the "embarrassing moments" thread. but thanks to you guys I learned something and that was worth it.
Thanks again.
Tom
