What is the typical voltage supplied to residential homes in the U.S.?

The typical voltage supplied to residential homes in the U.S. is 120/240 volts, which provides a standard electricity supply for household appliances and lighting. This system uses a split-phase configuration, where 120 volts is generally used for standard household appliances and light fixtures, while 240 volts is available for larger appliances like dryers and ovens.

The presence of both 120 and 240 volts in a residential setting allows for flexibility and efficient use of electrical power, catering to a wide range of appliance requirements. While 120 volts is optimal for running smaller devices, having 240 volts ensures that more power-hungry equipment operates effectively without overloading the electrical system.

This dual voltage supply is a standard approach in U.S. residential wiring systems and reflects its practical application in various domestic electrical needs.
