AUSGRID UNDERGROUND SERVICE MAINS

Underground service mains carry supply from an Ausgrid pillar or pit to your property, and they are the standard connection method across newer Ausgrid estates and many rebuilt streets on the North Shore and Inner West. Sydney Power Group is an Ausgrid authorised Level 2 ASP installing and repairing underground service mains throughout the Ausgrid network to current standards.

Underground Connections on the Ausgrid Network

An underground service main runs from the Ausgrid pillar box, through a compliant trench and conduit, to your metering position. Ausgrid specifies trench depth, cable type, conduit and marking requirements — all of which we meet as part of the install. See our underground mains service for the full scope, from new builds to replacing a failed underground run.

New Builds & Subdivisions

Most new dwellings and battle-axe subdivisions on the Ausgrid network now require an underground connection. We coordinate the new connection application with Ausgrid, install the service mains from the pillar to your switchboard, and arrange energisation — a single point of contact for your builder or project manager.

Repairing Failed Underground Mains

Underground cables can fail from age, ground movement, water ingress or excavation damage — often showing up as intermittent power or a dead property. This is Level 2 ASP work on the Ausgrid network. We locate the fault, replace the run in a compliant trench, and restore supply. If you have lost power completely, see our power outage electrician.

Done Right, Lodged With Ausgrid

Because an underground service main connects to the Ausgrid network, the work and its compliance must be handled by an authorised Level 2 ASP. We install to Ausgrid Network Standards and lodge the compliance so the connection is properly recorded. Call 0466 125 125 to book your underground service mains job.
