Underground Power Line Installation

Safe and Compliant Underground Power Line Installation

Underground power lines provide a safe and discreet way to supply electricity to homes and businesses. Many property owners choose underground supply for practical, aesthetic or safety reasons. When installing an underground service line it is essential that the work is carried out by a licensed Level 2 electrician who is trained and authorised to handle network connections. Fraser Electrical provides professional underground power line installation services across the Central Coast. We install new underground service lines, upgrade existing connections and ensure all work complies with Ausgrid and NSW Service and Installation Rules.

Underground lines offer a reliable alternative to overhead supply, particularly in areas where visual impact, weather protection or long-term durability are priorities. Our team has extensive experience installing underground consumer mains for new builds, renovations and property upgrades. We take a careful and methodical approach to every job to ensure your underground service line is safe, compliant and built to last.

Professional Underground Power Line Installation Services

Underground power lines sit below ground level and connect your property to the electrical network through buried conduits and cables. Because these lines form part of the network interface only authorised Level 2 electricians can install or upgrade them. Underground installations require attention to depth, protection, cable type and environmental factors to ensure long-term performance. Fraser Electrical manages the process from assessment to completion and ensures the installation meets all relevant requirements.

We work with single phase and three phase underground connections and use approved cable types designed for safe burial. Whether you are installing underground supply for a new build or replacing an existing line, we provide a safe and compliant solution.

Our Underground Line Installation Process

Underground installations require careful planning to ensure proper depth, protection and compliance. We follow a clear process to ensure the installation is safe and efficient.

1
Site Assessment

We assess your property to identify the best route for the underground cable, determine conduit requirements and confirm the installation meets Ausgrid standards.

2
Trenching and Conduit Preparation

We either work with your nominated contractor or arrange for the required trenching. The trench must meet the correct depth and width specifications. Conduits, marker tape and protective materials are then installed to meet safety requirements.

3
Cable Installation

The underground cable is pulled through the conduit and positioned correctly along the route. We ensure the cable is protected from abrasion, moisture and environmental exposure.

4
Network Connection

The cable is terminated at both the network pole or pit and the building’s point of supply. All terminations are completed by a licensed Level 2 electrician using approved fittings.

5
Testing and Compliance Checks

We test the entire underground service line to ensure correct operation and compliance. This includes verifying insulation resistance, load capacity and earthing integrity.

6
Backfilling and Finalisation

Once approved the trench can be backfilled and compacted. We then complete all reconnection work to place the underground service line into operation.

This methodical approach ensures your underground supply is installed correctly and built for long-term reliability.

Compliance & Safety

Safety and Compliance Requirements

Underground power line installation must be completed by a Level 2 Accredited Service Provider due to the requirement to work on network connection points. Fraser Electrical ensures all installations are completed in line with:

  • NSW Service and Installation Rules
  • Ausgrid requirements for underground mains
  • Local safety and environmental guidelines

Correct burial depth, conduit protection and termination techniques are essential for safety and must meet strict standards.

Benefits of Underground Power Line Installation

Underground service lines offer several advantages for property owners, particularly in areas where weather protection or presentation is a priority.

Improved Appearance

Underground supply removes visible cables from the property and helps maintain a clean exterior. Many owners prefer this option for modern homes or locations where overhead lines may be visually disruptive.

Reduced Exposure to Weather

Underground lines are protected from high winds, storms and falling branches. This reduces the risk of outages and physical damage to the service line.

Increased Safety

With no overhead cables there is less risk of accidental contact or damage caused by vehicles, ladders or nearby trees. This option is popular in areas with children or narrow access points.

Long-Term Durability

Underground cables are designed for long-term performance and protection against moisture, soil conditions and corrosion. When installed correctly they can offer many years of reliable service with minimal maintenance.

Ideal for High-Profile Properties

Homes with landscaped gardens, modern facades or premium outdoor areas often prefer underground supply for a cleaner and more streamlined appearance.

Overall, underground lines provide a safe and discreet supply method that works well for a wide variety of Central Coast properties.
