The sizing of an electrical panel is based on the total connected load. Most new homes today will use a minimum of 200 amp panel. This size distribution panel will give ample room for expansion in the future. As more and more appliances and larger connected loads appear on the market, distribution panels have gone from 30 to 60 to 100 to 125 and now the standard is 200 amps.

Should you upgrade your electrical panel from 70 to 100 amps?

If you are contemplating an electrical upgrade the 70 to 100 jump is not justified. Presuming that you are going to get a qualified electrical contractor to do the installation along with the proper permits, go to a 200 amp panel. Your labour costs are going to be the same no matter what size panel you get installed. The only difference in costs will be the materials. Go for a 200 amp 42 circuit distribution panel. It will increase your resale value of the house should you decide to sell in the future.
