Is this code compliant
I was asked to come down to farm home to bid the electrical on job for a fountain install to a small lake.
I ran into this for the GES while looking at equipment and panels. The 200 amp service equipment is mounted on the farm pole .. a 3 wire feeder is ran up the pole where they split it one 3 wire feeder to the dwelling and one 3 wire feeder to the barn. The feeder to the newer shop is fed from the barn panel and is a 4 wire feeder .. neutral and ground separated at the shop panel. The red lines are the feeders.
Probably barn and home are 50 years old so the 3 wire feeders would be compliant when they were installed.
However the barn and new shop are sharing the ground rods with the service equipment. I assume this is because the property is all rock and driving the ground rods in any compliant fashion for each building would be quite an effort.
Is this compliant ?
I have the answer from the county building department but I'm not sure I agree. Doesn't really matter but this is one of those things that I feel is a great learning tool when discussed on a forum. So I'm throwing it out there to see what your opinions are ...
