Adjacent to buildings, transformers must generally be located in accordance with the following requirements. First, a transformer must be installed with the front (doors) facing away from the building, with no balconies or overhangs above. The transformer must be accessible to line trucks (size and weight similar to a cement truck), for maintenance or replacement. Generally, a transformer located near a building requires 4ft clearance from the building vertical surfaces, assuming no windows from grade to 18ft. The sides of the transformer must be clear of all objects (including landscaping) for 3ft, and the transformer should be located 10ft horizontally from doors, windows or fire hydrants. The front (door side) of the transformer shall have a clearance of 10ft so that line crews can safely perform maintenance or repairs on the equipment. This required clearance includes landscaping. When encountering landscaping during emergency repairs, the utility can remove the landscaping (not very gently) or leave and await notification the offending vegetation has been removed. During routine maintenance, the utility will not attempt to work on the transformer until the landscaping has been removed.
