Hi fellas, well, here is another one. The situation is this one. I have an existing SES with an existing feeder which serves two panels. This feeder is tapped and something did not look right for me and the inspector.

We decided to provide a disconnect for each panel. Anyways,

One of the feeders is currently going underground out from the SES. My plan is to provide a disconnect for the tapped feeder right next to the SES. Therefore, I pretend to go out with my feeder to the new disconnect (right next of the SES, and then go in (again) the SES and "catch" and connect to the existing underground feeder wires. Basically just making a loop and using the SES as a Wireway.

I'm kind hesitating on this one, I am welcome to directions, thanks

The SES has 5 disconnects, the tapped feeder is done after after one of the disconnects. Therefore, I don't think it violates 230.7, since all wiring is done at the distribution section of the SES.

The issue is that I will have my feeder going out to a disconnect, then it will come back to the SES distribution section (i.e. basically from where the feeder originates) and then go underground to the Panel.

This is the part that kind'a makes me double think-it. Basically, I have the feeder disconnect (for the 2-tapped Panels), One set of the tapped wires goes to panel A, the other goes to panel B. Panel A goes overhead, outside the SES, but panel E is currently feed underground.

That is why I pretend to go out to two disconnects for panels A & B, disconnect A will go out the SES, "catch" the existing feeder A and connect-it to disconnect A, then go to the existing panel A.

Disconnect B will go also out of SES, but existing panel B feeder comes straight out underground the SES distibution Section. Therefore, I pretend to go out to the disconnect, then come back inside the SES distribution section and "catch" the underground feeder and go to the existing panel B .

How about this...??? What you think??

I don't understand "Service entrance section". Is this a metercan and one disconect feeding 2 feeders goining to differant locations?

The equipment enclosure where utility company connects to.
 
The way you are describing things is very cloudy to me. I understand your concern is a line and load side set of conductors sharing a nipple(?) from whatever enclosure the SES(which also confuses me) is into the disco.

If I understand what you want to do, I do not see a violation.
 
I'm confused...are you trying to use a 3-phase SES to feed 2 single phase panels of the same amperage as the SES? Or tapping an exsiting section to feed a smaller panel hence the need for a smaller disconnect? I just don't see the need for the extra disconnects unless its a convience thing. If you have a 5 sections... why not just tap the main bus for the extra disconnect to feed panel A, and leave panel B fed directly off the existing SES?

All that being said... I belive it is ok (although kind of tacky) to exit the SES and return to feed the underground conduit. Definetely safer than having service entrance conductors sharing the same trough with panel feeders.
