What is the typical capacity range of service entrance panels commonly installed in homes?

The typical capacity range for service entrance panels installed in homes generally falls between 100 to 200 amperes. This range accommodates the electrical needs of most residences, as it provides enough power to supply a variety of appliances, lighting, and HVAC systems commonly found in homes.

For many modern homes, a service entrance panel rated from 100 to 200 amperes is adequate. It allows for safe and efficient distribution of electricity throughout the house while meeting current electrical codes and standards. The lower end of the range often suffices for smaller homes or older properties, while the upper end supports larger homes with more electrical demands.

Other options listed may exceed what is typically necessary for average residential use. For example, 20 to 200 amperes includes a minimum that is less common for standard new installations, and the ranges of 50 to 300 amperes and 150 to 250 amperes presuppose larger electrical loads typically found in commercial settings or specialized residences. Thus, option B accurately represents the most widely used range for residential service entrance panels.
