Everything is debatable.;):D

If service laterals were not covered by the NEC then Part III of Article 230 would not exist.;)

If the service lateral in my picture were installed by the utility then I might agree with you that it is under the exclusive control of the utility.

Chris that is not a service raceway. Does it contain SE conductors? No. That is my debate and then let's look at the fault path.

Where does the NEC define a service raceway as containing only service entrance conductors?

Why would the fault path on a service lateral conduit be any different than the fault path on a raceway containing service entrance conductors?

Service point.
The point of connection between the utility and the premises wiring.
Service conductors.
The conductors from the service point to the service disconnecting means (service equipment, not meter). Service conductors include service-entrance conductors for overhead (service drop) and underground (service lateral).

Some hubs can be rotated changing the offset distance from the wall. This one needs to be rotated 180.

I agree.

The electrician wanted more room between the wall and the conduit so he rotated the hub 180 degrees, which made the hub out of alignment with the knock out.

That is exactly what happened, looks like a SQD HomeLine panel, they are the only one I have seen with a pre-tapped set of holes for the hub on the bottom.
Personally I think 300.5(G) is a little tough to enforce before the conductors are pulled because a big gob of duct seal fixes 300.5(G)
I do think that anyone who leaves that edge on the hub inlet needs to be slapped like a red headed step child.
 
looks more like the Milbank 400 amp meter mains our POCO specs. You have to use a hub on the bottom. If you use a 3" or above the lip hangs over, But it's still listed for use with no modifications because the lip is turned down.

Edited to correct myself. I just looked closer at the picture and realized that is a standard knockout.

I am now at total brain lock............:-? Who is determining service point? It is different in every county and POCO....:confused: Does anyone else see my confusion?

Yes the service point is determined by the utility and it has nothing to do with who installs the equipment. In our area we have raceway and conductors that are installed in the line side of the service point by the electrical contractor per the utility company rules. The installation on the line side of the service point is outside the scope of the NEC and the contractor installs per the utility company installation rules and not the NEC.
