Mains Power FAQs
What are mains power services?
Mains power services involve the electrical connection between the electricity network and your property’s switchboard. This includes the mains cable, protection devices, and the overall capacity of your power supply.
These services are essential when:
Power is being supplied to a property or structure for the first time
Existing mains cabling is old, damaged, or non-compliant
Electrical demand has increased due to upgrades or renovations
Safety or compliance issues have been identified
How do I know if my mains power needs an upgrade?
If you’re experiencing flickering lights, tripping breakers, frequent power outages, or your home still has old overhead lines, it may be time for a mains upgrade. An electrician can assess whether your supply is safe and capable of handling today’s power demands.
Can you underground my existing overhead lines?
Yes. At Alectrics, we specialise in the undergrounding of overhead lines, which improves safety, protects your supply from storm damage, and enhances the appearance of your property.
How much does a mains connection or upgrade cost?
Costs vary depending on the size of the supply, whether lines need to be undergrounded, and the complexity of the installation. Alectrics provides clear, upfront quotes so you know exactly what to expect.
Do you handle mains connections for new builds and subdivisions?
Yes. We provide mains connections for new residential builds, commercial projects, and subdivisions across Hamilton and the wider Waikato region.
Are mains upgrades covered by my electricity provider?
Some components may be the responsibility of your network provider, while others fall under the property owner. We’ll liaise with the network company on your behalf and handle the process from start to finish.
How deep is the trench for the cable for underground mains?
Depth varies depending on conditions, but it will comply with your network provider’s requirements and code.
