Outdoor Safety

Tree Limbs

If you’re planning on clearing tree limbs from our power lines, please make sure to check any encroaching power lines hidden within the tree limbs before you trim. You can contact 28344 or 21344 should you have any questions or concerns about tree limbs encroaching into our power lines.

Please keep trees and other vegetation that you own at your premises from encroaching on power lines from the minimum distance Set by Tonga Power:

Overhead Line Growth Limit Zone
11kV-High Voltage 2.0 meters
400V/230V – Low Voltage 1.0 metres

Before you Dig

If you’re planning on digging at home, please call 944 two days before you conduct your digging, so our workers can mark our underground service lines to ensure there is no damage and the area is safe.

Power Lines

Look up and look out for overhead power lines. Be mindful of any nearby lines before you climb a ladder or extend the handle of a pool-cleaning tool.

Keep materials, tools and all parts of your body at least 15 feet away from any overhead power lines at all times.
