Who Needs Overhead

Is an Overhead Supply Upgrade Right for Your Site?

Overhead connections are the most common supply method in Sydney. If your property already has an aerial cable from a street pole to your building, a 200A overhead upgrade is almost always the most cost-effective approach.

Understanding Overhead Supply

What Does an Overhead Connection Mean?

Overhead service mains run from the network street pole (or a private pole on your property) via aerial cable to the Point of Attachment on your building. This is the most common connection method across Sydney, Ausgrid, Endeavour Energy, and Essential Energy network areas.

Overhead connections are generally faster and more cost-effective to install than underground — but they require the correct pole height, clearances, and cable rated for the supply capacity.For a 200A overhead upgrade, the aerial cable, all terminations, and the Point of Attachment must all be correctly rated for the increased capacity. Where the existing pole height or cable span is insufficient, a private pole may be required to achieve the necessary clearances.

How a 200A Overhead Upgrade Works

From application to energisation — six clear steps, all managed by our team.

  • Maximum Demand Calculation
    We prepare a maximum demand calculation for your site — the technical assessment that forms the basis of your network application. This confirms 200A is the correct solution and ensures your application is accurate first time.
  • Network Application
    We prepare and submit your supply upgrade application to your distributor (Ausgrid, Endeavour Energy, or Essential Energy) — including your maximum demand calculation, site details, and proposed overhead supply configuration.
  • Network Assessment
    The distributor confirms whether sufficient capacity exists in the local network to support the upgrade. Most overhead 200A upgrades proceed without requiring additional network construction.
  • Network Construction (If Required)
    Where additional network capacity is needed, we coordinate Level 3 design and Level 1 ASP construction through our managed supply chain. You deal with one company throughout.
  • Level 2 Installation
    Our Level 2 ASP team installs the complete overhead 200A system — service mains, consumer mains, private pole (where required), earthing, switchboard, and metering. NOSW lodged on completion.
  • Energisation
    Your new 200A overhead supply is energised, tested, commissioned, and signed off. All compliance documentation issued — NOSW and CCEW.

Frequently Asked Questions

FAQs

Answers to the questions we hear most from Sydney homeowners, builders, and site managers.

What is a 200A overhead service mains upgrade?

A 200A overhead supply upgrade replaces your existing aerial cable with new, correctly rated service mains run from the network street pole (or a private pole) to your Point of Attachment. The cable, terminations, and Point of Attachment must all be rated for the increased 200A capacity. This work can only be carried out by a Level 2 Accredited Service Provider.

Do I need a private pole for a 200A overhead upgrade?

Not always. If your existing Point of Attachment and street pole are suitable, a private pole may not be required. We assess this at the quoting stage and include a private pole in scope where site conditions require it — either timber or steel, correctly rated for 200A.

How long does a 200A overhead upgrade take?

Once network approval is granted, a standard overhead installation is typically completed in a single day. Network applications with Ausgrid, Endeavour Energy, or Essential Energy generally take several weeks to assess — we'll provide a realistic timeline at the quoting stage.

    Can you manage the network application for me?

    Yes. We manage all communication with Ausgrid, Endeavour Energy, or Essential Energy — applications, approvals, outage coordination, and NOSW lodgement. You deal with us, not the distributor. This is one of the key advantages of working with a Level 2 ASP who specialises in supply upgrades.

      What is a Level 2 ASP and why do I need one?

      A Level 2 Accredited Service Provider (ASP) is the only type of electrician licenced by the NSW network distributors to carry out connection works — including supply upgrades, service mains installations, metering, and private pole work. A standard electrician is not authorised to perform a 200A supply upgrade. All work must be carried out by a Level 2 ASP with current accreditation under the relevant distributor.

        "Chris was the professional, punctual and his services are exceptional. Chris re-wired the entire property, chased the electrical work in the bathroom and kitchen areas, left a clean and tidy environment and his open communication and dialogue was a welcomed experience.

        When he quoted an arrival time, he was there. He talked me through what he was doing, and provided feedback/suggestions on how to tackle any issues. I felt part of the process, as opposed to being another Customer.

        A pleasure to deal with, and I recommend his services. I'll be definitely calling him again with any electrical work I need done."
