Transformer Installation Requirements
The information below is for general reference. Your Georgia Power Representative will work with you to determine requirements specific to your project.
Transformer Clearance Specifications:
- The selected location must be conducive to the installation of underground primary electrical cables.
- Available voltage
- The edge of the concrete pad nearest the building shall be:
- No closer than 14 ft. from doorways.
- No closer than 10 ft. from building wall, windows or other openings.
- If the building is 3 stories or less, the 10-ft. clearance is measured from the edge of any outside stairs, and covered walkways attached to or between buildings shall be considered part of the building.
Any exceptions to the above requirements must be approved by the local fire marshal or the jurisdiction having authority. Before seeking approval, contact Georgia Power Company to evaluate the feasibility of the exceptions. Written approval must be provided to Georgia Power Company.
Transformers shall be located such that:
- The front of the transformer faces away from the building.
- There are 10 ft. of clearance in front of the transformer doors.
- They are easily accessible by personnel and heavy equipment during construction and after project completion.
- If more than one pad-mounted transformer is required, the minimum spacing between transformers (including cooling fins) is 5 ft.
- There is unrestricted air flow for cooling requirements. Trees, shrubs, and other similar vegetation must be kept at least 10 ft. from all sides of the transformer.
