Common causes of cable faults
There are numerous ways a cable fault can occur, many of which are related to environmental conditions, installation errors, aging infrastructure, or accidental damage, such as:
- Excavation or construction damage
- Tree root intrusion
- Ageing or deteriorating cables
- Lightning strikes and electrical surges
- Water ingress and insulation failure
- Poor installation practices
- Overloaded or overheated cables
If you have an emergency and need to find a fault ASAP. How soon can you come?
Loss of power due to a cable fault is not only an inconvenience but in some cases could be life-threatening. We recognise this and accordingly provide a 24 hour emergency service. To us your safety is paramount.
Will I need to have an Electrician on-site?
Yes. Electricians are the specialists we require to ensure the site is prepared correctly for us to pinpoint the fault and undertake the work to fix the fault.
What if you can’t find a cable fault?
When we go out to a job site to find a cable fault, we typically look for two things. The first is that we need to find the actual cable itself. We will then look for the fault along that cable. If we don’t manage to detect a fault on the cable, we will not charge you for the cable fault detection part of the service; we will only invoice you for our time to find and mark out where the cable is. This then allows the electrician to undertake further examination to locate the fault.
If upon further investigation the fault is not where we indicated we will provide a refund for the fault detection component of our service.
Why Rapid Cable Fault Detection Matters
When underground cable faults occur, fast action is essential to minimise disruption and prevent escalating repair costs. And in some cases, it might be vital for home or worksite safety. Professional cable fault detection enables technicians to quickly identify fault locations, reducing unnecessary excavation and shortening restoration timeframes. Rapid fault investigation helps improve safety by reducing exposure to damaged electrical infrastructure while protecting surrounding assets from further damage. Accurate fault location also supports faster service restoration for homes, businesses and critical infrastructure. By addressing issues promptly, property owners and contractors can minimise downtime, reduce operational impacts and maintain the reliability of essential electrical networks.
