Ok here's a good one. I have 6 RV pedestals with 12 GFIs. (2 each) All the pedestals are 100 feet from their service disconnect. Three are served by 1 200 amp disconnect, 3 served by another 200 disconnect. All pedestals have seperate neutral and equipment groung. (all wired correctly as a subpanel, neutrals and grounds separated)all have suplimental ground rods connected to the ground bar only. Each pedestal has two 20 amp breakers serving two GFI receptacles (12 total). With no load, nothing plugged in or nothing connected to the load side of the GFIs, they all trip within a few minutes. Yep, all 12 with no load. All 6 problem pedestals are within the same area however, there are other pedestals near by and supplied from the same power co. transformer, wired exactly the same way, and have no issues. Any ideas?
