This is a good question.
What exactly were you inspecting if this was existing service?
I am still amazed that POCO gave a hoot about this feeder. As long as their meter and the first connect are to their specs, around here they could care less about the feeder going into the dwelling.
The law changed in Ohio a few years back because all manufactured homes have to be inspected per Federal mandated. New installs and any 'moving' of one of these units (resale). Someone explained the new rules to the POCO employees in an effort to help them not connect installations that may violate the code. The employees are well intentioned but are not code officials.
A home was on the site, then removed and a new home installed. For what reason I do not know the power was disconnected. So before the meter could be installed it had to be inspected.
I deemed the existing installation safe so I had to approve it regardless of how I would have installed it.
Some may say new home so the new rules apply. I could not justify that view. Some of us view that disconnect as a seperate structure. Some may not.
Existing installations are tricky to inspect. While most of the time the code takes judgement out of our hands there are times when we have no choice but to use our judgement.
