AS2550.1 Powerline distancesPowerline distances “Look up and live!”

Always check overhead for powerlines and make sure you and any equipment or materials you are using do not come into contact with them.

The safe operating distances for working near powerlines are outlined on the following pages.

A spotter is required if you are working between 3 to 6.4 metres from distribution lines on poles.

The term ‘spotter’ is defined as a safety observer who is a person competent for the sole task of observing and warning against unsafe approach to overhead powerlines and other electrical apparatus.

Overhead powerlines on poles (National Standard)These are usually ‘Low Voltage’. This means powerlines of less than 133KV.

The information below is taken from the National Standard.

Always check the distances for your state or territory, as they may be different.

In some states or territories a spotter must be qualified.


AS2550.1 Powerline distancesA spotter is required if you are working between 8 to 10 metres from transmission lines on towers.

The term ‘spotter’ is defined as a safety observer who is a person competent for the sole task of observing and warning against unsafe approach to overhead powerlines and other electrical apparatus.

Overhead powerlines on towers (National Standard)These are usually ‘High Voltage’. This means powerlines of more than 133KV.

The information below is taken from the National Standard.

Always check the distances for your state or territory, as they may be different.
