What is the typical voltage for residential electrical systems in North America?

The typical voltage for residential electrical systems in North America is indeed 120/240 volts. In residential settings, the electrical system generally utilizes both 120 volts and 240 volts.

In most homes, standard outlets are wired for 120 volts, which is commonly used for lighting, appliances, and other everyday electrical devices. Meanwhile, larger appliances such as dryers, stoves, and air conditioners often require 240 volts to operate efficiently, which is provided from the same service panel by utilizing different wiring configurations.

This dual voltage system allows for versatile electrical service that can accommodate various devices and appliances, ensuring adequate power availability depending on the specific needs of the household. Understanding this configuration is essential for maintenance and installation of residential electrical systems.
