What is the standard residential voltage in North America?

The standard residential voltage in North America is 120 volts, which is the level used for most household appliances, lighting, and outlets. This voltage level is part of the electrical system's design to ensure safety and compatibility among various devices, as well as easy integration with the electrical grid.

In most North American homes, you will typically find two types of electrical service: 120 volts and 240 volts, with 120 volts being the standard for common household circuits. The 240 volts is often used for larger appliances, such as dryers and ovens, which require more power to operate efficiently. The choice of 120 volts helps to minimize the risk of electrical shock and ensures that wiring and device ratings are standardized for safety across all residential applications.
