The continuity of the grounded conductor in a multiwire branch circuit cannot depend on which component?

In a multiwire branch circuit, the continuity of the grounded conductor is essential for ensuring safety and proper functioning of the electrical system. The grounded conductor, often referred to as the neutral wire, must maintain its integrity throughout the entire circuit.

The receptacle itself serves as a connection point for devices that use power; however, it is not a determining factor for the continuity of the grounded conductor. If a receptacle fails or is improperly installed, it can lead to an open circuit, affecting the load but not necessarily disrupting the path of the grounded conductor back to the power source. Thus, the receptacle does not actively maintain or influence the continuity of the grounded conductor, making it the correct choice in this context.

In contrast, the power supply, switch, and breaker are all devices that are critical to the functionality and operation of the electrical circuit. The power supply provides the source voltage and must ensure the continuity of the grounded conductor in conjunction with the circuit. The switch controls the flow of electricity, and if the switch is open in a multiwire circuit, it can affect the entire circuit's continuity, including the neutral path. Similarly, a breaker is designed to protect the circuit and maintain safety, and it plays a vital role in ensuring that the grounded
