What is the typical voltage for residential wiring in the United States?

The typical voltage for residential wiring in the United States is 120 volts. This is the standard voltage for most household circuits, serving general lighting and outlets for everyday appliances. The electrical systems are designed to provide 120 volts to ensure compatibility with a variety of devices, as the majority of common household appliances, tools, and consumer electronics are designed to operate at this voltage.

In addition to 120 volts, it's also important to note that some larger appliances, such as ovens, dryers, and HVAC systems, may require higher voltages of 240 volts. However, the standard for general use in residential settings remains at 120 volts. Understanding this is crucial for both safe wiring practices and working with electrical devices within the home.
