Is ground-fault protection required at all installations and locations?

The requirement for ground-fault protection varies based on the installation type and location, making the second choice accurate. Ground-fault protection is essential for safety in many environments, especially where water and electricity may come into contact, such as residential bathrooms or kitchens. However, there are specific settings, particularly in certain industrial or outdoor locations, where ground-fault protection may not be mandated by code, or where alternate safety measures are considered sufficient.

This understanding reflects the nuances of electrical codes and regulations which allow for exceptions based on risk assessments, usage contexts, and specific building codes that may apply to a given facility. Therefore, while ground-fault protection is critical in many installations, it is not universally required in every scenario, confirming that some locations may not necessitate such measures.
