Final answer:
A split-wired duplex receptacle, also known as a split receptacle, provides independent control of the top and bottom outlets. Each outlet has its own hot wire connection and can be controlled by separate switches.
Step-by-step explanation:
A split-wired duplex receptacle, also known as a split receptacle, is different from an ordinary duplex receptacle because it allows for independent control of the top and bottom outlets. In a split receptacle, each outlet has its own hot wire connection and can be controlled by separate switches. This allows for more flexibility in how the outlets are used. For example, you can have a lamp plugged into the top outlet that is controlled by a switch, while the bottom outlet remains always on for other devices.
