What is the common voltage level for residential circuits?

The common voltage level for residential circuits is typically 120/240 volts. In most residential settings in North America, the standard voltage for outlets is 120 volts. However, larger appliances, such as dryers and ovens, often require 240 volts. This dual-voltage system allows homes to efficiently supply power for a range of devices and appliances, maximizing versatility and functionality.

Understanding the residential voltage system is crucial for linemen and electricians, as it informs installation, maintenance, and troubleshooting processes. The 120/240 volt configuration is designed for safety and efficiency, providing both lower voltage for general use and higher voltage for heavy-duty equipment.
