I need an opinion. I recently completed a small 100 amp residential service upgrade. SE cable enters main disconnect with feeder cable then traveling on to a service sub-panel about 50 feet away.
Grounding electrode conductor goes from the main disconnect to the water pipe, connected within 5 feet of where it enters the building. I drove a ground rod and connected that to the sub-panel (due to convienent location).
AHJ failed job saying that the ground rod needed to be connected directly back to the main disconnect, and could not be connected to the service sub-panel.
I pointed out 2008 NEC 250.64 (F-1) thinking that would cover me. Still, no.
Why is it OK to bond a ground rod to say, the water pipe, but it can't be run back to a service sub-panel? This inspector is very good, so I'm assuming I'm missing something here. Thanks.
