Altered service/feeder without EGC

Visited a remodel site today. The service comes in directly underneath the planned addition to the house so the GC asks what we need to do to move it. It's fed from at least 300' away and has a main disconnect(meter/main) at the transformer. The part I found strange is there is no EGC run with feeders and this is relatively new construction. Are these service conductors or feeders?

My thought is to cut the feed near to the house, install another disconnect, then route the rest of the new feed to noodle through the new addition. At this point I would think it's prudent to add in the EGC, downstream my new disconnect. I'm not sure I could legally not add a ground, right?

Thanks
 
Service conductors. If the disconnect is not service equipment (just a disconnect) the service conductors pass through to the building where the main will be. This is like we need to do many times with the now required outside disconnects. Either you can make it the main service disconnect or just a disconnect. So, what you are thinking of doing is fine. After the main you have a 4 conductor SER feeder through the addition and the panel inside is a sub panel.

If you add the new disconnect, do your bonding and earthing there, and run a 4-wire feeder from there.
 
So how do you differentiate service conductors vs feeders in this case?

On one hand there is overcurrent protection, but on the other there are only 3 wires

Generally that's the difference... It's service until you get to your 1st overcurrent device.
 
That's what I thought. So these could be feeders even though there is no EGC run?

The definition makes a big difference in this case
