Planning a mains power upgrade?
Omzen Electric specialises in single to three-phase conversions, replacing ageing mains cables and transitioning to underground power. Our expert team ensures every upgrade is carefully planned and safely delivered, tailored to suit your property’s requirements.
Why You Might Need a Mains Supply Upgrade?
Increasing Supply Capacity
Modern properties and renovations often need more power to support all-electric homes. Upgrading to 3 phase ensures your system can handle the increased load.
Unsafe Mains Cabling
Old or damaged mains cables can pose serious safety risks. Upgrading helps prevent faults, outages, and potential hazards.
Aesthetic Requirements
Switching to underground mains removes overhead lines for a cleaner, more streamlined look that suits modern design.
Possum Protection
Underground power eliminates access points in the roof, helping protect your premises from possum entry and damage.

“The Omzen Electric team came to the rescue when we lost power to our Holiday Accommodation Park just days before Christmas, our busiest time of the year. They excavated over 150 meters to repair the underground mains and had our power back on faster than we could have ever hoped.
We’re so grateful for how quickly they were on site the day the power went down and all their expertise in repairing the damaged cables and pit.”
About Underground Electrical
Underground electrical refers to an electrical system that delivers power through buried cables and conduits rather than overhead wires.
This approach is becoming increasingly popular for residential new builds and renovations when installing new electrical connections or mains upgrades, due to its aesthetic benefits and greater resistance to weather-related damage.
While underground systems offer improved safety and a cleaner look, they can be more expensive to install. Choosing an electrical contractor with a team experienced in underground works and the right excavating equipment can significantly reduce the cost and increase the efficiency of your works.
Why Underground Electrical Systems Are the Future
Many construction projects are now opting for underground electrical infrastructure due to its reliability and visual appeal. By burying cables, you reduce the risk of damage from storms or falling trees, while also improving the look of your property.
Our team at Omzen Electric provides comprehensive underground electrical services for our client’s across Melbourne. We specialise in everything from the installation of new residential connections and mains upgrades to excavation for commercial repairs and civil services.
