Avalon Underground Cabling Specialists

Installing underground cabling involves several coordinated stages to ensure compliance and reliability. We begin with a comprehensive site assessment to determine the most suitable cable route, identify any obstacles, and assess soil conditions. Following this, we liaise with Ausgrid to obtain necessary approvals and arrange network connections. The physical installation begins with trenching to the required depth according to Australian Standards, typically deeper beneath driveways or areas with vehicular traffic. We then lay durable electrical conduit to protect the cables, position the cables correctly within the conduit, and install warning tape above the cables to alert future excavators. After backfilling the trench with appropriate material and compacting it properly, we make all electrical connections at both the network connection point and your switchboard. Finally, we conduct thorough testing and commissioning to verify everything operates safely and efficiently. Throughout this process, we coordinate closely with you to minimise disruption to your property and landscaping.

Selecting the appropriate underground cable involves careful analysis of several technical factors to ensure your electrical system performs optimally. We assess your current and anticipated electrical load, considering all appliances, systems, and equipment that will draw power. The distance from the connection point to your switchboard influences voltage drop calculations, which help determine the minimum cable size needed. We verify whether you require single-phase or three-phase power based on your electrical demands. Soil conditions at your property, including moisture levels and soil type, affect heat dissipation and may influence cable selection. We also consider any future electrical upgrades you might be planning, such as adding pools, workshops, or EV chargers. Based on these factors, we specify cables that comply with Australian Standards and Ausgrid requirements, typically using XLPE insulated cables or SDI cables depending on the specific application. Our Level 2 electricians ensure the selected cables provide adequate capacity with appropriate safety margins for reliable, long-term performance.

If you suspect an underground cable fault, taking prompt action helps prevent further damage and safety hazards. Common signs include intermittent power loss, flickering lights, tripped circuit breakers, or unusual electrical behaviour. In these situations, avoid attempting any repairs yourself, as underground electrical work requires specialised equipment and Level 2 certification. Contact our team immediately for professional assessment. We use advanced cable fault location equipment to pinpoint the exact location of faults without extensive excavation, which saves both time and disruption to your property. Once we've identified the fault, we'll explain the issue, outline repair options, and provide transparent recommendations. Depending on the severity, repairs might involve cable jointing, insulation repair, or complete cable replacement in affected sections. If the fault poses an immediate safety risk, we can arrange emergency isolation and temporary power solutions while permanent repairs are completed. Our priority is restoring your electrical supply safely and efficiently with minimal inconvenience.

Underground electrical cabling that connects to or affects the electricity network requires specific approvals that only Level 2 electricians can obtain and action. Before commencing work, we coordinate with Ausgrid to lodge connection applications and obtain necessary service orders. This ensures the work is authorised and that network assets are protected throughout the installation. Depending on your project scope, you may also need development approval or construction certificates from your local council, particularly for new builds or major renovations. If the underground cable route crosses public land, footpaths, or roads, additional permits may be required. Fortunately, as experienced Level 2 electricians, we handle these administrative requirements on your behalf, managing all communications with distributors and authorities. We ensure every aspect of your underground cabling project complies with relevant regulations, Australian Standards, and local requirements. This comprehensive approach protects you from potential compliance issues and ensures your electrical installation is fully authorised and legally compliant from start to finish.
