What is the standard electrical service in a residental home?

The standard electrical service in a residential home in the United States is typically 120/240 volts, provided through a split-phase system. Most homes are equipped with a 200-amp service panel, which can accommodate the electrical demands of modern appliances and devices. This service allows for both 120-volt circuits for general use and 240-volt circuits for heavier appliances, such as dryers and ovens. Local regulations and specific home needs may result in variations in service size.
