How should transformers or other electrical units be located to minimize risk?

• A. Totally enclosed or placed 15 ft above the ground, or in housing or a fence 6 ft high, and 3 ft from energized parts
• B. Left exposed on the ground
• C. Mounted directly on equipment
• D. Submerged in water

Answer: (A)

Keeping transformers and similar electrical units safe hinges on preventing accidental contact and limiting exposure to energized parts, arcing, and weather. The best approach is to place them in a totally enclosed case or raise them well above ground (about 15 ft), or place them in a protected housing or behind a fence at least 6 ft high, with a clearance of about 3 ft from any energized parts. This setup reduces the chance of someone touching live components, helps contain any arc faults, and shields the equipment from moisture and damage. Leaving units exposed on the ground, mounting them directly on other equipment, or submerging them in water creates obvious hazards: greater risk of contact or short circuits, moisture-related insulation problems, and dangerous arcing or electrocution.
