: [AFMUG] another grounding scenario ??
Common point neutral is a good thing.
But distributed earth grounds for the true ground circuit is good too.
The main thing you want to accomplish for safety’s sake is to allow fault
currents to find the lowest impedance path to ground as possible. It is OK to

Earth ground circuits are also important to allow circuit breakers to

help with that. I would drive ground rods. But I would also make sure

are floating and not bonded. That would prevent ground loops for the normal

The general rule is one grounding point. However, if the sub panels are
far enough apart and/or the interconnecting ground wire is too small,
you might consider adding another ground rod. I'm guessing that the
distance to your tower is far enough away from the original ground and
the interconne
The electricians that I have spoken with say bond to existing power ground
and then pound another rod right at your connection. That is what we've
always done.

We are doing a new tower. Here's the layout
Customer house (Building "A") has a small building (Building "B" for discussion
purposes) about 150 feet away from main house. "B" has a sub-panel and 5 live
breakers for various things. There is a 6 gauge ground wire between "B" and
the Customer h
