The Western Australian Distribution Connections Manual (PDF 6.4mb) is a comprehensive single reference point for establishing a residential and commercial electrical connection of an customers installation to either a Horizon Power or our distribution network.
Section 11 of the WADCM also details the requirements for the supply, installation and connection of 15 volt CT metering equipment, meter panels and wiring.
The Design and quote application form is necessary to arrange for CT metering when there will be no increase in demand - e.g. when replacing an existing switchboard or metering.
Direct connected metering
Section 11 of the WADCM describes the available metering options for customers and the various requirements for each type of system.
This information should be read in conjunction with the Western Australian Electrical Requirements (WAER), published by EnergySafety.
AMR systems must also be approved by us before they can be installed in the customers installation. Section 11 of the WADCM details the policies and technical requirements for the installation and use of AMR systems.
To initiate the process the developer/AMR system installer is required to complete and submit an AMR Application Form to our Metering Services Group as detailed on the attached application form.
If you disagree with the application of an inspector's order (I-type), you can request a review of the re-inspection fee (PDF 98KB) by completing the form.
If you would like us to undertake work on behalf of your customers you should complete a request for Western Power network service. Once agreement is established, and we have received the preliminary notice, we will bill you for the services.
The process for submitting notices is different, depending on whether the load is contestable or not..
Non contestable loads
For anticipated loads below 5.7KW (50MWh/year), the process is:
- send your design and quote application form and preliminary notice to our connections office - Locked Bag 2025, Perth WA 6001
- connect the underground consumer mains to the power dome and install a meter (assuming the electrical contractor is appropriately accredited)
Note: You can use electronic ticketing (ETIC) to submit forms; however, you will not be able to enter a value into the calculated maximum demand field on the preliminary and completion notices for new connections of 100 amps or more. A maximum demand of this size strongly indicates that the customer is contestable and hence the contestable loads process applies.
For anticipated loads above 5.7KW (50MWh/year), the process is:
- send your design and quote application form and preliminary notice to our connections office - Locked Bag 2025, Perth WA 6001 - with the comment "anticipated load to exceed 5.7kW"
- advise your customer to choose a retailer as soon as possible, as the electrical connections cannot proceed until network access services has accepted the individual nomination for your customer from a retailer
Note: Electrical contractors cannot install meters for any load that will exceed 5.7kw (50MWh/year).
