The electrical load of a home is calculated by doing what is called a load calculation. The load calculation takes into account the total square footage of livable space, along with all electrical loads. The majority of homes will never need anything larger than 200 amps. Installation of 100 amp or 200 amp service costs the same in labor but the difference is in material cost. We typically recommend a 200 amp service in most cases as the owner will get the best resale value.
Even if you don’t have quite as many large electrical systems, it might be a good idea to upgrade if you use a lot of electrical appliances. Upgrading to a 200 amp panel will make more electrical power available to appliances that need it, boosting their efficiency and effectiveness.
