If transformers cannot be fully enclosed, where should they be placed?

Transformers that cannot be fully enclosed should be placed in a specific and strategic manner to ensure both safety and compliance with regulations. The correct choice indicates that transformers should be located in a transformer house, elevated to at least 8 feet off the ground, or within a secured area fenced at 6 feet in height.

This approach is crucial because it helps prevent unauthorized access and protects people and property from potential electrical hazards like arcing, shocks, or other dangers associated with high voltage equipment. Elevating the transformers or enclosing them within a fenced-off area minimizes the risk of accidental contact and enhances overall site safety. Additionally, this practice also takes into consideration environmental factors, such as drainage, which can affect the transformer if not properly managed.

Placement on the ground could expose the transformer to flooding or unauthorized personnel, while placing it inside a building may not provide adequate ventilation or comply with safety standards. Ground level installations with warning signs alone do not sufficiently mitigate the risk of accidents or provide adequate protection measures compared to the recommended option.
