Upgrading your power supply
If you are installing new equipment or using appliances that need a larger or three-phase power supply, you may need to:
- upgrade your supply connection
- convert your supply connection to three-phase
- install a current transformer (CT) meter or
- upgrade your existing CT meter
If you have already installed new equipment and have noticed a change in the quality of your power supply, call 13 13 51.

This will become obvious when we assess your application for a power upgrade.
Additional costs for three-phase power are outlined in network charges and pole to pillar connection and may also include:
- the cost of a three-phase meter (arranged and billed through your electricity retailer)
- electrical contractor's costs to run an underground cable from the pillar to the meter box and any changes necessary for internal wiring
