How can most duplex receptacles be converted into "split-wired" receptacles?

Most duplex receptacles can be converted into "split-wired" receptacles by breaking off the small metal tab on the terminals. This tab connects the two outlets of the receptacle so that they share the same circuit. When a duplex receptacle is left intact, both outlets function together, meaning that they receive power from the same circuit.

By breaking off this tab, you allow each outlet to be fed by a different circuit. This modification enables one outlet to be powered by one circuit while the other can be powered by another, providing more flexibility for electrical load management and accommodating higher power needs without overloading a single circuit.

This process effectively creates two independent outlets from a single receptacle, thus allowing for appliances or devices with varying power requirements to be plugged in separately and safely. It’s a useful configuration, especially in situations where multiple devices need to be powered simultaneously.
