Electrician's Licensing Practice Exam

Which statement describes a grounded conductor?

1. It is a conductor intentionally connected to ground

2. It is a conductor used exclusively for power distribution

3. It refers to a circuit breaker

4. It is a conductor that supports voltage stability

The correct answer is: It is a conductor intentionally connected to ground

A grounded conductor is specifically defined as a conductor that is intentionally connected to the ground system of an electrical installation. This connection allows for the safe dissipation of electrical energy into the earth in the event of a fault, which helps protect both people and equipment from electrical shock or damage. By having this intentional connection, a grounded conductor plays a crucial role in establishing a reference point for the electrical system, ensuring safe operation and increasing reliability. In contrast, other options present concepts that do not align with the specific definition of a grounded conductor. For example, conductors used exclusively for power distribution do not necessarily imply that they are connected to the ground, nor do circuit breakers refer directly to grounded conductors. Lastly, the idea of a conductor supporting voltage stability does not encapsulate the purpose and characteristics of a grounded conductor, which specifically focuses on its connection to the ground.
