I want to ground 2 or 3 outlets and discussed going to a water pipe method here. Everyone mentioned the "5 foot rule" per NEC. Some were concerned about the ground not tripping the breaker. I have had nothing but problems finding a good electrician in my town!!! I think I finally did and want input on his plan.
Talking on the phone, he proposed the following and said it would pass code (local):
1. Drive 8 foot ground rod and connect to panel. 2. From desired ungrounded receptacle(s) go through floor to crawlspace with ground wire and run back to panel. 3. One receptacle is for pc, and he suggested doing same method, but use new wire and make it a dedicated circuit so there would be no interference or something with pc. Not sure if this is necessary?
In doing the above, how specifically should it be done to meet NEC?
If I understand, it will still need to be bonded to the water pipe. Should that be within 5 foot of water entrance point? And can you bond it to more than one place (i.e. to the 5 foot and also close to panel?). I'm still not up to speed on this bonding concept, hence the question.
Is there a specific way of doing it so that it will ensure that it trips the breaker? Do the grounds go IN the panel or are they attached to ground rod (assuming ground rod is attached to panel). Does it matter?
At what point (if any) can the ground wires be combined into one? I seem to remember something about you couldn't use a junction box-- everyone had to have a home run. I just don't understand enough about this to know where that home run ends?
Not sure if this is relate to the above, but he did mention something about "looping" the grounds--but I am not sure where he meant that or what it means.
Hopefully, that is a good enough description that you can not only answer questions, but raise any issues that you forsee (as you can tell, I am not too up on electrical).
