Where should manhole openings for personnel be located in relation to electrical equipment?

1. Directly above electrical equipment

2. At least 1 foot away from the equipment

3. Not directly above electrical equipment

4. Anywhere accessible for maintenance

The correct answer is: Not directly above electrical equipment

Manhole openings for personnel should be located not directly above electrical equipment to ensure the safety of personnel working in the area. This is crucial because placing manhole openings directly above electrical equipment can pose risks such as electrocution or injury in case of an unexpected equipment failure or if maintenance is required. By avoiding this placement, it provides a safer environment for workers, ensuring they are not exposed to potential hazards associated with electrical equipment. Locating manhole openings at least 1 foot away or in any accessible location might still present risks if they are placed directly above electrical components. The emphasis on the correct placement is to prioritize the safety of the personnel and to comply with best-practice standards in electrical maintenance and operation.
