Residential underground service upgrade 150-200 amps

[Greg1707]

I have done a lot of above ground service upgrades. This will be my first underground. The existing service is 150 amp and the meter can appears to be 200 amps and in good condition. I am not sure how the POCO handles their end of the project. Do I just splice the old SEC to the upgraded SEC and the POCO deals with landing the SEC in the can?

What are you upgrading? Are you going from 150A to 200A?
If you are, all you do is run new-larger wire from the meter to the panel/disconnect. You don't splice anything.
POCO will most likely leave their wire as it may already be able to handle 200A.
If they do need to upsize their wire it's still up to them to pull in new wire and land it in the meter.
Depending on the POCO, they may charge for the wire but in all cases they will pull and land the wire.

Thanks, I just want to confirm the POCO will terminate the new SEC in the can. I do not want to do that.

I highly doubt the poco will change the underground portion for a 150 to 200 amp upgrade, assuming it's their responsibility in the first place. Our poco does not own service laterals so we would have to replace it here. At any rate, many poco's run 1/0 AL for 200 amp services anyway if it's under their jurisdiction.

Seems you need to ask that POCO. You might get different answer with different POCO.

BTW, SEC (service entrance conductor) in your case is technically what is between the meter and the service disconnect, those underground conductors in your case are either underground service conductors service lateral conductors - depending on which side the "service point" they are located on.
