    Frequently Asked Questions

    FAQs

    Why should I consider switching to underground electrical services?

    Underground installations are safer, as they are less susceptible to weather damage and accidents. They also enhance the visual appeal of your property and can increase its value by removing unsightly poles and overhead wires.

    Are underground cables more expensive than overhead lines?

    The initial installation of underground cables can be more costly, but the long-term benefits of reduced maintenance, increased safety, and aesthetics can offset the initial investment.

    Can you upgrade my existing underground cables?

    Yes, we offer services to upgrade your existing underground system to accommodate increased power requirements or to replace ageing infrastructure.

      How deep do underground service mains need to be buried?

      Under AS/NZS 3000, underground consumer mains must generally be buried at a minimum depth of 600mm, though this can vary depending on the surface material and whether mechanical protection such as a concrete slab is present.

        What cable and conduit is used for underground service mains?

        Professional installations typically use XLPE-insulated cable run through heavy-duty PVC conduit, with warning tape laid above the conduit to alert anyone digging later of the buried service.

          "Chris was the professional, punctual and his services are exceptional. Chris re-wired the entire property, chased the electrical work in the bathroom and kitchen areas, left a clean and tidy environment and his open communication and dialogue was a welcomed experience.

          When he quoted an arrival time, he was there. He talked me through what he was doing, and provided feedback/suggestions on how to tackle any issues. I felt part of the process, as opposed to being another Customer.

          A pleasure to deal with, and I recommend his services. I'll be definitely calling him again with any electrical work I need done."
