What is the minimum recommended service amperage required for a new single-family home?

The minimum recommended service amperage for a new single-family home is 100 amps. This standard is based on the needs of typical modern households, which often require a significant amount of electrical power to operate various appliances, lighting, heating, and cooling systems. While it is technically possible for some smaller homes to operate on lower amperage, such as 60 or 75 amps, these levels are inadequate for most contemporary residential needs.

A service amperage of 100 amps provides a reasonable capacity for the majority of electrical demands, ensuring that home systems can function without overloading the electrical service. This level also allows for future expansion or the addition of electrical devices and systems as the homeowner's needs evolve. Therefore, establishing a service connection of at least 100 amps helps ensure a safe and effective electrical supply for the home.
