We make an electrical enclosure that is sold all over the U.S. I have had a couple customers tell me that two different inspectors in two different states asked them to connect a ground rod directly to our factory installed equipment ground lug. By directly connecting the ground rod, I mean that you screw the lug set screw down on the ground rod. According to these customers, the inspectors would not allow a bonding wire between any lug and the ground rod. When they determined that wasn't possible with our lug, the inspectors told them to install a field lug bonded onto the enclosure and then directly connect a ground rod to the field lug. Why would anyone disallow a bonding wire, especially one that is short? Thanks.
