I would think that would be illegal. They don't have jurisdiction on
supply side taps. It's past the meter, and expressly allowed in the
NEC. I would definitely first ask to talk to a higher level person than
the one denying it (paper trail important). If that does not work, then
the PSC is y
Kris,
Are they telling you the problem is the connection in the meter base? We get
this all the time from local utilities. Even with the listed Milbanks like you
describe, they say no and direct us to tap on the load side of the meter base.
I agree that you may consider an informal complaint
Hi Kris.
Here in Southern Oregon our utility if Pacific Power. They also will not
allow us to do any kind of connection of tap inside the meter box even with
code approved connection methods. They consider the meter can "their

Thanks for all the discussion and insight. I believe the main issue here
is them being territorial about the meter socket (they did not install it
and they do not own it). My follow up question to them was, "I assume that
you allow a 320 A meter socket feeding two main panels. Is this
different?
Hopefully Wisconsin is better than Minnesota about this. As a former
Wisconsin resident, I doubt it...but here is how some of this works in
Minnesota, lest you have any illusion that a PSC or a state cares about you.
In Minnesota the state allows the utility to essentially make any
interconnec
Others have pointed this out, but I thought I'd just add a bit of info
based on my experience - the issue is not so much whether you can do a
supply side connection or not, as that is allowed in the code. The issue is
whether you can do wiring in a section of equipment that is only for the
utility.
There's very "territorial" language in the 2020 NEC 705.11(D):
"For meter socket enclosures or other equipment under the exclusive control
of the electric utility, only connections approved by the electric utility
shall be permitted."

Hey Jason,
Here's the 2020 text:

loads and fault currents.

Of course the feeder conductors and bus bar could be subjected to a fault.
But we're not talking about faults here. Fault protection is the job of the

feeders. If that wasn't the case, you would need a new OCPD on BOTH the

This scenario is certainly allowed, but since it's not at the end of the

The feeder ampacity shall be not less than the sum of the primary source

I'm not following you. How is this not at the end of the feeder? The feeder
terminates at the main breaker in the subpanel.
