Bonding only one end isn't always an option. We think this way because we often install grounded services. When installing an ungrounded service, you have no choice* but to bond both ends, because there is no grounded conductor to bond the enclosure.fair enough...it's a 2" nipple so it seems really silly to me and not to mention I have to be able to explain this to employees. I really don't like doing something because someone simply said to...that can make things really confusing. I am grateful for the patience and feedback!
*Running a bonding jumper would work, but it pretty much defeats what you are trying to get away with in the first place.
