Overhead power

An Overhead service is an aerial cable that is connected to the network power pole from your point of attachment. The point of attachment will either be on a private pole or on the front of your premises. From there, the feeder cables (consumer mains) will run to your main switchboard. Overhead power generally works out to be highly cost-effective as there is no excavation work required and the cable is run in aluminium, not copper which is less expensive to buy.

Some examples where new overhead services may be required are:

  • For three phase upgrades
  • Dropping and reinstating for crane lifts
  • During mains Installation Overhead 100A-400A
  • For temporary Builders Supplies
  • During relocation to avoid the boundary crossings
  • Replacement due to damage

Underground power

These services are your form of supply when the network in your area is underground, which simply means the absence of poles and wires overhead.

Underground service cables work by a connection to the closest utility company’s network pillar, to your point of attachment,whether it be your private pillar or main switchboard.

The advantage of underground power is that there will be no visible wires present which can eradicate the likelihood of damage by weather events. Underground feeds also give a much cleaner look as you won’t find any power poles strung around your area.

Some examples where new underground services may be required are:

  • When setting up new housing estates
  • You require private networks
  • 3 Phase upgrades
  • For mains installation underground up to large supply demands
  • Temporary Builders Supplies
  • Due to damage

Underground supplies can also be achieved from overhead networks in the form of a UGOH (underground to overhead) installation. please see UGOH for more information.


UGOH is an abbreviated form of underground to overhead connection. You will need this kind of connection when the power in your area is from poles and wires, but you want your supply to come to your premises underground from the street, eliminating the need for having an aerial cable. To solve this, the supply cable will run down the pole and then underground to your property.

Reasons for using a UGOH are:

  • An alternative to having an aerial cable run across your property
  • You do not want a private pole at the front of your premises but need to avoid boundary crossings
  • You are not allowed to have a private pole on your premises due to council restrictions

Power disconnection and reconnection

You might require disconnection and reconnection services if the power supply in your residence has been disconnected, or if you have undergone any construction works on your home or building.

Some examples where new disconnection and reconnection services may be required are:

  • Permanent disconnections, removal of meters and aerial service for demolishing
  • When you need new mains or service equipment
  • Installation, repairs and replacement of riser brackets and point of attachment hooks
  • For isolation due to tree trimming or tree removal
  • Service Fuse and Barge Fuse installation or repair at the point of attachment, single and three-phase
  • For roofing and guttering repairs or replacements
  • For isolation in conjunction with scaffolding work
  • For isolation during Crane lifts such as pool installs
