A grounded neutral wire can be used as an equipment ground. True or False?

The statement that a grounded neutral wire can be used as an equipment ground is false. In modern electrical systems, the neutral wire, which is intended to carry current back to the source, should not be relied upon as a grounding conductor. The primary role of the grounded neutral is to provide a return path for electrical currents under normal operating conditions, whereas the equipment ground serves as a safety path to divert electrical faults away from users and equipment.

Using a neutral as a ground can create significant safety risks, such as overloading the neutral during fault conditions, which could lead to electrical shock hazards. Additionally, this practice can cause potential differences between the ground and neutral, posing risks to equipment and personnel. Regulations, such as the National Electrical Code (NEC) in the United States, mandate that equipment grounds and neutral conductors are separate to ensure electrical safety and effective fault protection.
