How much power do I need?

Most residential homes have a ‘single phase’ or ‘three phase’ connection supplying 230 volts. For a modern family home, this connection is often 60 amps for a single phase, or 32 amps across three phases. Your fusing could be more or less if your house is smaller, larger, or was built at a time when fewer electrical devices were used around the home.

Small commercial buildings usually need more capacity, such as 100 or 200 amps. Large commercial stores or warehouses could need 400 amps to 1200 amps of capacity depending on their size.

Your capacity needs will vary depending on the amount of power you are using at your property, and there is no "standard capacity" or one-size fits all.

New Power Connection

The New Power Connection application is submitted to MainPower

The customer or someone working on behalf of the customer (like an electrician) will submit an online application for a new power connection to MainPower.

MainPower processes the application

MainPower will issue a new Installation Control Point (ICP) number. This takes a maximum of three working days.

MainPower advises the retailer of the new connection request

MainPower needs to advise the retailer of the new power connection. Once this is done, the retailer needs to confirm the details with the customer directly. This process takes approximately five working days.

Retailer accepts the new power connection

Once the retailer has contacted the customer directly and is satisfied with the details, they will approve the connection.

At this point, two things happen at once.

Electrician/ customer requests the power to be turned on by the Livening Agent

Once the retailer has approved the connection, the electrician/ customer will arrange with/ engage the Livening Agent to have the power connected. The Livening Agent is the organisation who will carry out the actual process of turning the power on to the property.

Retailer sends request to metering/ Livening Agent to install meter

At the same time, the retailer will advise MainPower they have approved the new power connection and retailer will also submit a service request to the Livening Agent to have the power connected. The Livening Agent is the organisation who will carry out the actual process of turning the power on to the property.

Livening Agent turns the power on to the new connection

The Livening Agent will liven the power supply.

Connection complete

The new power connection is now live! The Livening Agent will confirm with MainPower and the retailer that they have successfully turned the power on. The retailer will advise the customer that the new power connection is now live.
