28 Clark Public Utilities Commercial Electric Service Handbook Transformer location and access Underground electrical facilities must be readily accessible by the utility during construction and for future operation and maintenance. The area around padmounted electrical equipment must provide a clear and level working space and remain free from obstructions such as landscaping, poles, retaining walls, structures, fences, etc. All transformers and padmounted equipment are to be located: Within 0 feet of a drivable surface but not closer than feet (Figure ). With the front of the equipment (door and lock side) facing toward the drivable surface. With the transformer pad parallel to the edge of the drivable surface. Allowing 0 feet of clearance in front and feet from the back and sides of the equipment (Figure ). At least feet from a sidewalk for pedestrian safety.

The clearance from a building is 0 feet if the building has combustible walls, and feet if the building has non-combustible walls as shown in Figure. Table provides additional safety clearances that apply to any oil-filled electrical equipment.
