Please Be Safe Around Padmount Transformers

Padmount transformers are the big green steel utility boxes commonly seen around town and in neighborhoods. These devices serve the purpose of lowering high voltage to standard service voltage for your home or business.

The green padmount transformers are the same as the gray cylinder transformers you see on utility poles, but they are mounted on the ground because the electric service wires are underground. Although padmount transformers are designed to be safe, with a case covering the transformer and conduit around the wires, they are still a critical piece of electrical equipment that can house more than 7,200 volts of electricity.

Always use caution around padmount transformers and never use them as workbenches or climbing obstacles. Barriers, such as landscaping or fencing, should be kept clear as well. While it can be tempting to hide them with landscaping, please remember that Central Lincoln crews need at least 10 feet of clearance, or distance, at the opening of the transformer and 3 feet at the rear and sides. This clearance allows them to safely work on the equipment.

Padmount transformers are connected to primary high-voltage lines, and secondary lines can extend in several directions underground. Before planting trees or shrubs, setting fence posts, installing sprinkler systems, or digging anywhere near a transformer, you should know the location of these lines. Anyone who plans to dig should call 811, the national call-before-you-dig phone number, or submit a line locate request at
