When a new power pole is needed — for a subdivision, network upgrade, or pole replacement — the first step is excavating the hole. This is called a pole hole.
What is a pole hole?
A pole hole is the bored or excavated opening in the ground into which a power pole is set. Dimensions depend on:
- The height and class of the pole
- Soil type (clay, rock, sand)
- The load the pole will carry
- The relevant DNSP construction standard
How are pole holes drilled?
Most NSW pole holes are drilled using an auger — a rotating bit on a truck-mounted or tractor-mounted rig. In rocky ground, rock-breaking equipment may be required. Hand-digging is used where machinery access is restricted.
How deep does a pole hole need to be?
As a general guide, poles are set to approximately one-sixth of their total length below ground plus 600mm. An 11-metre pole typically requires a hole around 2.4 metres deep. Exact depth is determined by pole class, load calculations, and soil conditions.
Pole setting and backfill
The pole is craned or lifted into position and set vertically. The hole is backfilled in layers with compacted soil or concrete depending on soil type and DNSP requirements.

Private power pole installation in NSW
Private power pole work needs the correct pole location, service height, earthing, point of attachment and distributor approval pathway. A Level 2 ASP is commonly required where the pole connects a private service line to the electricity network.
- Confirm whether the property is supplied by Ausgrid, Endeavour Energy or Essential Energy.
- Check clearances from driveways, trees, buildings and overhead service lines.
- Coordinate any planned outage, disconnection and reconnection before the pole is replaced or installed.
- Rectify related defect notice items before the site is re-energised.
Common questions
Who can install a private power pole in NSW?
A licensed electrician may complete some private electrical work, but network connection and authorised service work usually requires a Level 2 ASP.
How quickly should a defective private pole be repaired?
Defect notices include a deadline. Storm damage, leaning poles and unsafe service lines should be assessed urgently.
