Electrical Main Panel

Helloooooo FABO!
(Asking for a friend, but Ill tell the story in the 1st person format:rolleyes:)

I am remodeling my basement into a mother in law situation. New framing and re plumbed the house with expansion type A PEX. I am on to the electric and am running a sub panel. In that transition I am swapping out the main panel to a more updated version. The panel coming out is 200 AMP. The panel going in is 200 AMP. The new panel gives me room to put in the new 100 AMP breaker for the sub panel. In this process I am planning on pulling the meter to cut power. I am driving in two 10' grounding rods as the plumbing is now pex and the old system utilized the galvanized pipes for the ground. I am isolating the grounds on the sub panel and will probably not drive in another ground rod for it, but utilize the main water pipe (updated to 1" copper). After switch is complete I will try to not have a power draw by having all breakers off. I will re insert meter and turn on breakers one by one. Yes I have wired stuff before that had to be inspected (new construction), but I havent done this scenario before.

What am I missing besides the clip the city puts on the meter? and am I looking for trouble when they find it missing? Maybe I can get one on Ebay? The meter is the fancy digital ones. would the city get a signal that Im messing around?

Be gentle now. Just a guy over here standing in water holding a lightning rod in a thunderstorm.

Thanks FABO!!!
