Which statement best describes pad-mounted transformers?

• A. They are located on the ground inside a fenced enclosure with restricted access
• B. They are located on poles
• C. They are portable handheld devices
• D. They are underground with no enclosure

Answer: (A)

Pad-mounted transformers are ground installations that sit on a concrete pad at ground level and are housed in a locked, weatherproof enclosure within a fenced area. This design keeps high-voltage equipment safely contained and accessible only to authorized personnel, which is essential for safety and maintenance. They are used in distribution systems where underground or partially underground service feeds step down voltage, and the transformer itself remains on the surface with restricted access for protection. They are not mounted on poles, not portable handheld devices, and not located underground without an enclosure.
