Identifying Service and Power Lines

Distribution Lines

The wooden poles that run along roads and connect to homes and businesses are called distribution lines. These lines power our everyday lives but can be damaged by improperly planted or weakened trees. Closely monitor the growth of any trees near distribution lines on your property

Transmission Lines

Transmission lines are large wooden or steel poles that transfer high-voltage power, and often run across the landscape or behind homes. Because these lines carry such high voltages, We have established rights of way where vegetation growth around transmission lines is strictly regulated to prevent damage.

Electric Line vs. Telephone or Cable Line

• High-voltage electric lines are always at or near the top of the pole. These lines are usually found along neighborhood streets, but they may also be located in backyards or across open fields.
• If more than one utility line (telephone or cable) is mounted on the same pole, the high-voltage electric lines are at the top of the pole.
• A low-voltage electric line is located several feet below the high-voltage line.
• The low-voltage line attaches to your service weather head (a protective device is located where the line is to your residence.)

The diagram below should also help you to identify electric lines.

Important Note: During or after any storm event, consider all downed wires to be energized and dangerous, including telephone, fiber optic, and cable TV wires. They may be in contact with energized electric wires that are not within your view. To report downed electric wires, please call 1-800-465-1212.
