I recently purchased a vacation home that was foreclosed on and hasn't had power for a couple of years (meter has been removed by electric company). The panel in the house is a 20 space 100 amp that is rusted with breakers that are stuck. Before the power company comes to reinstall the meter (and power) I wanted to replace the panel and I was wondering if it is possible or even recommended to step up to a 40 space 200 amp panel. At this point I am not planning to upgrade the service (current wire to the house appears to be #3), but I may want to do so in the future. What can/should I do to future proof myself and is there downside (or special things I would need to do) because it would only be a 100amp service? Also on a related note would it also be a good idea to add a disconnect at this time?
