What is a common voltage classification for residential areas?

The common voltage classification for residential areas is 120V. This voltage level is standard in North American households, where it is typically used to power everyday electrical devices such as appliances, lights, and electronics. The 120V supply is easily manageable and safe for consumer use, making it the ideal voltage for residential applications.

In contrast, voltages like 560V and 480V are generally reserved for industrial or commercial settings where higher power is needed for heavy machinery or equipment. These higher voltages would be inappropriate and unsafe for typical home use. Similarly, while 230V is used in many parts of the world for residential applications, it is not the standard in North America, where 120V predominates. Thus, 120V is recognized as the baseline voltage for residential electrical systems.
