I'm looking to replace the aging 200A Main Panel with a new panel for additional circuits. I see a lot of 225A panels (https://www.leviton.com/en/products/lp622-mb) and interested in a 225A versus 200A. In new Main Panel, I will try and stay ahead of the 2020 NEC curve and basically install the combined AFCI + GFCI breakers. I already have whole-home surge protection to bring over.
I am confused about how I would get to use a 225A panel when the meter-box is 200A. Additionally, I want to try and not replace the meter socket due to cost, and would get this project done before November when is suspect Vermont will go with 2020 standards. I am also hesitant to replace it, due to the need for two-meter socket with main breakers in order to do net-metering. So I would either have to buy that now (and the pains that come with that service upgrade) or waste money now and buy it again later.
Due to the number of branch circuits and then that most breakers would fall into the combined breaker, I am already looking at a project cost of about $1500 for main panel. (They don't give these circuit protection breakers away, even if I went Square-D or Eaton.)
- Vermont Home, built 1980
- Existing Panel: 200A Cutler Murray, never replaced
- Ground - Single ground rod
- Meter Socket: 200A socket, replaced 15 years ago.
- Panel problem: Rust and corrosion, likely due to flood ~1990. Breakers starting to need replacement
- Power is overhead service, meter is located in space constrained area
garage sub panel - 100A 2-pole breaker, 2-2-2 URD wire installed in conduit. Installed circa 2000. Has it's own grounding rod. Main Breaker subpanel. Garage has air compressor, welder, and car lift.
Shed sub panel - 50A 2-pole breaker, 2-2-2 URD wire in conduit. Installed circa 2000. Grounding Rod installed, but main lug panel. Note: likely to be replaced soon, we shall see. Has 3x 20A circuits for lights + some network gear
- Solar Panels
- EV unlikely

After some thought, i have 3 questions.
a) Can i put a 225A main panel beyond a meter socket/meter rated for 200A? I assume no. 2) When replacing the main panel, can i preserve the pre-2008 NEC rules for the shed and garage and not run new wiring (2-2-2-2-4) to those structers? 3) with replacing the main panel, anything else i might run into? Smoke alarms? wiring to exiting outlets, etc? I know I have 12/2 wiring to everything in the house. I will likely add a second grounding rod just for good measure.
