What happens when the break-off connection tab between the brass terminals of a receptacle is removed?

When the break-off connection tab between the brass terminals of a receptacle is removed, it allows for the connections of separate circuits to each outlet. In a standard duplex receptacle, the brass terminals are typically connected by a metal tab, which means that both outlets share the same circuitry. By removing this tab, you can isolate each outlet, enabling one to be connected to a different circuit than the other. This feature is particularly useful in scenarios where you might want to control power to one receptacle while keeping the other powered, like in areas where appliances may have different voltage or amperage needs.

The other choices do not correctly describe the outcome of removing the break-off tab. Color coding of wires is generally related to the identification of wire types rather than the function of the tab. Removing the tab does not eliminate the need for a neutral wire, as neutral is still required in electrical circuits for proper grounding and safety. Additionally, the modification does not create a parallel circuit, but simply allows for individual connections, as the outlets can still operate on the same circuit if desired.
