What Are Overhead Service Mains?
Overhead service mains are essential components of electrical distribution systems, responsible for transmitting power from utility poles directly to your property's electrical system. Unlike underground mains, which are buried, overhead mains are installed above ground on poles and are visible throughout neighbourhoods and along streets. The primary advantage of overhead mains is their accessibility for maintenance and lower installation costs compared to underground systems.

Common Reasons for Upgrading Overhead Service Mains
Clients often require upgrades or new installations due to:
- Increased Power Requirements
Upgrading equipment or expanding facilities can necessitate higher capacity overhead mains. - Environmental Damage
Exposure to severe weather can impair existing infrastructure, requiring comprehensive assessments and replacements. - Property Renovations
Changes in property layout or function often lead to modifications in the electrical system to support new demands.
Overhead vs Underground — Which Is Right for You?
Overhead service mains are generally the more affordable, accessible option, running above ground from a utility pole to your point of attachment. They're easier and cheaper to inspect and repair than buried alternatives, and less prone to ground-level issues like digging damage or flooding — though in low-clearance areas near trees or structures, a Tiger Tail safety cover may be recommended.

FAQs
The duration for installing or upgrading overhead service mains can vary depending on several factors such as the complexity of the project, the length of the mains to be installed, the condition of existing infrastructure, and weather conditions. Typically, a straightforward installation or upgrade could take anywhere from a few hours to a couple of days.
You might consider an overhead service mains upgrade if you experience any of the following:
- Frequent Power Outages
If you are experiencing regular interruptions in your power supply that are not related to broader electrical grid issues, it might be a sign that your current service mains are inadequate. - Addition of Major Appliances
Installing appliances that consume a significant amount of power, such as HVAC systems, electric vehicle charging stations, or large manufacturing equipment, may require more power than your current setup can safely supply. - Renovations or Expansions
Any renovation or expansion that increases the area of your property or adds significant electrical loads might necessitate an upgrade to ensure that your electrical system can handle the increased demand safely. - Signs of Wear and Tear
Visible wear or damage to cables, frequent tripping of circuit breakers, or issues with power quality (like flickering lights) can also indicate that your current system might need an upgrade.
Overhead service mains run above ground from a utility pole to your property's point of attachment, generally costing less to install and easier to inspect and repair. Underground service mains are buried and better protected from storm damage, but involve trenching and typically cost more.
The point of attachment is where the overhead service line connects to your property, typically mounted on the fascia under the gutter or on a private power pole where a fascia connection isn't suitable. It must meet minimum clearance heights required by Australian Standards and network operator rules.
Overhead installation is generally the more affordable option compared to underground, with cost depending on cable length, single vs three-phase requirements, point of attachment work, and site access. A site assessment gives the most accurate figure for your property.
Where an overhead run has low clearance near trees or structures, a Tiger Tail safety cover may be required or recommended to reduce fire and safety risk. We can assess whether your overhead mains need this protection.
