Multiunit Meter Center Load Side Feeder

[rruelas]

I'm working on a multi unit residential building with several feeders leaving a multi unit meter center. Each feeder leaves in its own conduit but then due to length periodically we want to have a pull box. The contractor I'm working with wants to put a large pull box and have several of the feeders pass through. The question we are struggling with is once these feeders enter the pull box, are we required to provide separation barriers inside the pull box to keep all feeders separated. We are having trouble finding anything in the code indicating such separation would be required.

Thanks in advance

You are having trouble finding it because there is no such requirement.

Follow up question. In my opinion if the multiple meter center is where my utility source conductors terminate and that is the location where the ground to neutral bond occurs, that in effect becomes my service entrance. All these feeds from the multiple meter center become feeders and are not service entrance conductors, so they fall under the scope of Chapter 3 and not article 230? Any opinions?

Feeders would fall under the scope of Article 215.

Thanks for the clarification, Yes, 215, but 230 has some restrictions on service entrance conductors. What I was getting at is that anything in article 230 is not applicable to feeders from the Load side of the meter center to each tenants panel.

Thanks in advance.

You did not actually say whether there are service disconnects at the meter. I assumed there was since you have been using the term "feeders" (just sometimes people dont use the correct terms, its good to confirm). If you have no disconnects at the meters, you could theoretically be using 230.40 exception #1 to continue out of the meters with service entrance conductors. But if you have service disconnects at the meter then yes they are feeders and not article 230 conductors.

Thank you very much for your input. Yes, each meter in the stack has a main breaker in the stack right next to the meter socket (would have been helpful if I mentioned that). Additionally the tap box at the start of the meter socket line up also has a main breaker (2000A) and the neutral to ground bond occurs at that location.
