Specialist 200A overhead service mains upgrades for Harrington Park homes, granny flats and small commercial sites. Maximum demand calculations, Endeavour Energy applications and full Level 2 installation — managed by one team, energised on the day promised.
Is a 200A Overhead Upgrade Right for Your Harrington Park Property?
Harrington Park sits in the Endeavour Energy network. If you have an existing aerial cable from a street pole to your property in 2567, a 200A overhead upgrade is almost always the most cost-effective path. We assess every Harrington Park site for correct cable rating, pole height, clearances and Point of Attachment before we quote — so the price you sign is the price you pay.

What an Overhead Connection Means in Harrington Park
Overhead service mains run from the Endeavour Energy street pole (or a private pole on your block) via aerial cable to the Point of Attachment on your building. It's the most common connection method in Harrington Park — faster and more cost-effective to install than underground.
For a 200A overhead upgrade, the aerial cable, all terminations, and the Point of Attachment must 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 above driveways and structures on your Harrington Park property.

FAQs
What is a 200A overhead service mains upgrade in Harrington Park?
A 200A overhead supply upgrade replaces your existing aerial cable with new, correctly rated service mains run from the Endeavour Energy street pole (or a private pole on your block) to the Point of Attachment on your Harrington Park building. 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 an overhead upgrade in Harrington Park?
Not always. If your existing Point of Attachment and the Endeavour Energy street pole are suitable, a private pole may not be required. On larger Harrington Park blocks a private pole is often needed to achieve the required clearances. We assess this at the quoting stage and include a private pole (timber or steel, 200A rated) where site conditions require it.
How long does a 200A overhead upgrade take in Harrington Park?
Once Endeavour Energy approval is granted, a standard overhead installation in Harrington Park is typically completed in a single day. Network applications generally take 2–4 weeks to assess. We'll provide a realistic timeline at the quoting stage.
Can you manage the Endeavour Energy application for me?
Yes. We manage all communication with Endeavour 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 in Harrington Park?
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 in Harrington Park or anywhere else in the Endeavour Energy network. All work must be carried out by a Level 2 ASP with current Endeavour Energy accreditation.
