Cut an Underground Cable? Stop Digging — Then Call Us, 24/7
The auger jolted, the breaker tripped, and half the house went dark — or worse, the digger's bucket is sitting on something that's still live. A severed underground power cable is both an outage and a serious hazard. High Demand Electrical repairs cut underground consumer mains 24/7 across Sydney, from make-safe to reconnection.

Just Hit a Cable? Do This Now
The minutes after a cable strike are when people get hurt — usually by going back for another look. Follow this order, then call 0402 559 777.
- Step away from the excavation and keep everyone else away — the cut ends may still be live even if power tripped.
- Don't touch the cable, the tool that hit it, or the machine — an excavator in contact with a live cable can be energised.
- If someone has received a shock, call 000 first.
- Leave the hole open and undisturbed — burying the evidence makes repair slower and more expensive.

From Strike to Supply Restored
Cable strike repairs are urgent, regulated and entirely Level 2 — here's how we run them.
Emergency isolation
The damaged run is de-energised and proven dead under our authorisation — making the site safe for everyone including your contractors.
Damage assessment
Severed or crushed sections identified — strikes often damage more cable than the visible cut, so we test both directions.
Proper jointing or section replacement
Rated underground joints installed — or the damaged section replaced where crushing extends beyond the strike point.
Compliant reinstatement
Conduit, marker tape and correct depth on the repaired run — so the next fence post finds tape, not cable.
Test and reconnect
Insulation testing to standard, then supply restored under our Level 2 authorisation with certification.
How Cables Get Cut
The same tools appear in these stories every week — if you're about to use one, read the last card first.
Fence Post Augers
The number one culprit — fast, deep and blind. Old cable runs cross fence lines more often than anyone expects.
Excavators and Mini-Diggers
Trenching for plumbing, pools and footings finds cables that were never marked — or never laid where the plan says.
Stump Grinders and Tree Work
Roots and cables share the same ground — grinding a stump over a cable run ends predictably.
Landscaping and Irrigation Work
Shallow old runs — sometimes barely a spade deep — meet garden renovations constantly.
Driveway and Concreting Works
Formwork pegs and compaction damage cable that's then entombed — faults surface months later.
Prevention: Dial Before You Dig
Free national service (call 1100 or byda.com.au) maps registered services — and we can trace private runs the plans don't show before your project starts.

FAQs
I cut a power cable while digging. Is it still dangerous if the power tripped?
Treat it as live regardless. Protection may have tripped one side while the other end remains energised, damaged cables can re-energise, and wet ground conducts. Keep everyone away from the excavation and the machine, and call 0402 559 777 — we isolate and prove it dead first, always.
Who pays for a cut cable — me, my contractor, or insurance?
If a contractor cut it, their public liability insurance typically covers the repair; if it was your own project, home insurance may contribute depending on policy. Either way our incident documentation — photos, cause report, itemised repair quote — supports whichever claim applies. The repair itself can't wait for the paperwork; make-safe comes first.
How long does it take to repair a severed underground cable?
Once located and excavated — which your strike has usually done for us — most joints are completed, tested and reconnected the same visit. Crushed runs needing section replacement can take longer; you'll get an honest timeline and upfront quote on arrival.
