220-volt circuit

A 220-volt circuit refers to an electrical system designed to operate at 220 volts, commonly used for powering heavy-duty appliances and equipment that require higher voltage than standard household circuits. These circuits are essential for safely delivering electricity to devices such as ovens, dryers, air conditioners, and industrial machinery. Understanding 220-volt circuits is important for proper installation, maintenance, and troubleshooting to ensure safety and efficiency in residential and commercial electrical systems.
