OSHA #511 Occupational Safety and Health Standards for General Industry course

What is the function of an equipment grounding conductor?

1. To serve as the main power supply to machines

2. To safeguard against insulation failure or faults

3. To increase electrical resistance

4. To act as a primary circuit for electrical appliances

The correct answer is: To safeguard against insulation failure or faults

The function of an equipment grounding conductor is primarily to safeguard against insulation failure or faults. This conductor provides a safe path for electrical current to flow back to the ground in the event of a fault, such as a short circuit or equipment malfunction. By doing so, it helps to prevent electric shock hazards and minimizes the risk of fire caused by faulty electrical equipment. When electrical insulation deteriorates or fails, the grounding conductor helps ensure that any stray currents are directed safely away from people and sensitive equipment. This is essential in maintaining safety in environments where electrical equipment is used, as it reduces the potential for accidents and injuries related to electrical faults. Proper grounding is a fundamental component of electrical safety standards and regulations that aim to protect workers and equipment in various industries.
