Question: 1 / 715

What is the primary difference between a neutral wire and a ground wire?

The ground carries current; the neutral does not

The neutral normally carries current; the ground does not

The primary difference between a neutral wire and a ground wire is that the neutral wire is designed to carry current during normal operation, while the ground wire is not intended to conduct current unless there is a fault or abnormal condition in the system. The neutral wire serves as a return path for the current flowing through the electrical circuit and is essential for the functioning of electrical devices. In contrast, the ground wire is a safety feature that provides a path for fault current to return to the ground, helping to prevent electric shock and equipment damage.

This distinction is crucial for ensuring safe and effective electrical system operation. Understanding the roles of neutral and ground wires assists technicians in properly wiring circuits and conducting safe troubleshooting practices.
