All I'm finding locally are 225-Amp panels. We have 200-amp service and the main breaker for each residence is outside with unit # labels. I don't have a need for add'l circuits etc at this time, but the new panel is a value pak and comes with 5 breakers all for $100. It supports Plug on Neutrals which I'll probably use for 6-7 AFCI breakers. Any consideration to consider bc it's a 225-Amp vs 200-amp panel? I'm not planning any new circuits but I get 10 extra spaces in the new box and eliminate the tandems and put in all new breakers. The service conductors come thru a metal conduit. Is that functioning as the ground back to the main in my case? Here's the panel I plan to use. https://www.lowes.com/pd/Square-D-225-Amp-30-Spaces-60-Circuit-Convertible-Main-Breaker-Panel-Plug-On-Neutral-Load-Center-Value-Pack/50311151
I am eliminating the tandems on the new panel.
