Consumer Mains Installation & Replacement in Balmain East

Consumer mains are the cables that run from the point of supply, where your property connects to the network, to your meter panel and main switchboard. They carry all of the electricity your property uses and form part of your private electrical installation.

Service mains (the service line) are the network cables that run from the street pole or pit to your point of supply. Consumer mains continue from the point of supply into your property. In the Ausgrid area the network looks after its street infrastructure, while the property owner is responsible for the consumer mains, point of attachment hardware and safety clearances on their side of the connection.

Replace consumer mains when the insulation or connections are damaged or deteriorated, when the cable is too small for your current or planned load, when a defect notice identifies a problem, or when you are changing the supply arrangement, for example moving to three-phase or underground.

The cost depends on cable length and size, overhead or underground installation, trenching, access, single or three-phase supply, switchboard and metering changes, and any network requirements. Because these vary so much, we inspect the property and provide a written quote rather than a fixed price.

Yes. Underground consumer mains are installed in conduit from the network pit or pillar to the meter position, in line with AS/NZS 3000 and the NSW Service and Installation Rules. Converting an existing overhead connection to underground also involves the network connection arrangement, so we assess feasibility and requirements at inspection.

Consumer mains are electrical installation work and must be carried out by a licensed electrician and certified on completion. Disconnecting and reconnecting your supply at the network, and working on the service line, must be done by an Accredited Service Provider Level 2. HD Inner West holds Level 2 accreditation, so one team can complete both parts of the job.

In most cases, yes. Replacing consumer mains usually means the supply has to be disconnected and reconnected at the network side, which is Level 2 work. Using a Level 2 electrician for the whole job avoids coordinating two separate contractors.

Yes, where the network can supply three-phase power to your street. The upgrade involves an application to Ausgrid, new three-phase consumer mains, and switchboard and metering changes. See our single-phase to three-phase upgrade service.

A straightforward like-for-like replacement is often completed on site in a day, with the power off for part of that time. Underground runs, three-phase upgrades and jobs that need network approval take longer, and approvals add lead time before work starts. We confirm timing in your quote.

Changes to your connection, such as increased capacity, three-phase supply, a new connection or a relocated point of supply, need an application or notification to Ausgrid, which we lodge for you. The electrical work itself does not usually need council approval, but work in the footpath or road reserve, or visible changes on some heritage properties, may need council permission.

Yes. Loose, corroded or overheated connections can cause flickering, partial loss of power and intermittent outages, and a failed cable can cut supply to the whole property. Damaged mains are also a fire and shock hazard, so have them checked promptly.

Ausgrid requires defects to be repaired within 21 days of notification, or the supply may be disconnected until the work is made safe. You should engage the original contractor or a Level 2 ASP. We can inspect, rectify the consumer mains defect and complete the paperwork. Learn more about defect notice rectification.
