My lake cabin is located aproximately 300 feet from my service drop. At
the meter I have a 200 AMP main service panel with disconnect. It is
grounded to an 8' copper rod in the ground. The Neutral buss and ground
are bonded in case.
From this box I am running a three wire feeder (two 4/0 ungrounded hots and
one 2/0 neutral) to a 200 AMP subpanel on the cabin itself.
There are no continous metallic paths bonded to the grounding system in
both boxes, therefore there are no parallel neutral paths running between
them.
The lake cabin has interior copper plumbing attached to a PVC water main.
Questions:
1. Do I need a secondary grounding rod at the cabin
2. If so, do I isolate the neutral from the ground in the subpanel?
2. Do I need to bond the plumbing to the neutral buss or the ground in the
subpanel?
Thanks in advance.
