What is my service entrance rated for?
It is an underground entrance with two 1/0 hot leads and a #2 neutral. The charts I have seen read the 1/0 is rated 175 amps but the #2 is only 125 amps. So with the neutral being smaller does that mean the entrance is only rated for 125 amps?

When discussing poco service cables things are a little different. They don't follow the NEC code the same as we do.
However, cables run thru a conduit are limited in ampacity.
More than likely your service cables are aluminum. 1/0 is 135A max.

The neutral is allowed to be sized smaller than the ungrounded hot conductors. The service size is not based on the neutral size.
