No Power After Storm in Sydney – What to Check

Emergency? Call now

24/7 response across Sydney metro · Licensed Level 2 ASP

0433 462 902 Book Online

Fallen network lines, a tripped RCD, a blown service fuse, or storm-damaged switchboard wiring are the most common causes of power loss after a Sydney storm. If you smell burning, see scorch marks, or find a damaged meter box, the hazard is live — book a 24/7 emergency inspection or call Sydney Electrical Service on 0433 462 902 immediately.

Sydney’s storm season — east-coast lows, summer thunderstorms, and southerly busters — can dump 80 mm of rain and 100 km/h winds in under an hour, leaving thousands of homes across every metropolitan suburb without power. This page is the action checklist: what to look at, in sequence, so you can isolate the fault fast and turn a multi-day outage into a same-day fix.

When You Must Call a Licensed Electrician

Call Sydney Electrical Service on 0433 462 902 if any of the following apply:

Network supply is restored but your home is still out
The main switch will not stay reset
Damage to overhead lines, point of attachment, or meter box
Smell of burning at the switchboard
Visible water inside the meter box or switchboard
An RCD that will not reset
Surge damage to multiple devices across multiple circuits
Solar PV system has not auto-restarted
Tingles or shocks from any metalwork
Concerns about smoke alarm or hardwired safety system function

We are licensed Level 2 ASP contractors and can restore consumer-mains, point-of-attachment, and switchboard faults in a single visit, often without a separate Ausgrid attendance.

Why DIY Is Dangerous and Illegal in NSW

Storm-affected installations are uniquely hazardous:

Lines that “look dead” can re-energise without warning when network crews restore upstream
Water inside switchboards or outdoor enclosures re-establishes leakage paths the moment power returns
Damaged surge protection has no visible indicator until it fails again
Capacitive equipment (motors, transformers) can hold charge after isolation

Under NSW law, all fixed wiring work must be performed by a licensed electrician, and any work on the supply side requires a Level 2 ASP under the *Service and Installation Rules of NSW*. The *Gas and Electricity (Consumer Safety) Act 2017* makes unlicensed wiring work a prosecutable offence. Storm insurance claims involving unlicensed repair are routinely refused.

Frequently Asked Questions

The whole street is out — should I still call you?

Not yet. Confirm via the Ausgrid (13 13 88) or Endeavour Energy outage map first. We can't help until the network is restored. Once neighbours have power and your home is still out, call us.

The power came back on but my main switch keeps tripping. Why?

Storm damage often leaves residual moisture or surge effects that don't show until power returns. A tripping main switch indicates a downstream fault — water in an outdoor circuit, surge damage to an appliance, or compromised wiring.

Should I dry the switchboard with a hairdryer?

No. Never work inside an energised or potentially energised switchboard. A wet board must be professionally isolated, dried, tested, and re-certified before being put back into service.

Can I just leave outdoor circuits off until summer ends?

You can — but the underlying fault doesn't fix itself, and the damage typically worsens as water sits. We recommend a Level 2 inspection within 7 days of any storm-related outdoor circuit fault.

My solar isn't working. Is that an emergency?

If the rest of the home has power and the solar is just inactive, no — book us for a non-urgent inspection. If the solar is faulted in a way that prevents the main switch resetting, yes.

The point of attachment is loose. Whose responsibility is it?

The point of attachment hardware (bracket and insulator on your home) is the property owner's responsibility. The service main itself is Ausgrid's. Repairs and replacement are licensed Level 2 ASP work — we handle this routinely.

What about my food in the freezer?

A typical full freezer holds ~24 hours; a half-empty one ~12 hours. Don't open it. After 24+ hours of outage, perishables should be assessed individually. Keep receipts for any spoiled food — your contents insurance may cover it.

How quickly can you respond after a major storm?

During peak storm response we are running 2–4 hour ETAs across Sydney. We prioritise active fire risk, fallen lines, wet switchboards, medical-dependence customers, and elderly residents. Call 0433 462 902 as early as possible to lock in your slot.

Is it safe to reset my RCD myself after a storm?

Yes — if the switchboard area is dry, there are no burning smells, and there are no visible scorch marks, you can press the RCD back to ON yourself. If it trips again immediately or won't reset at all, there is an active fault on that circuit and it must stay off until a licensed electrician has inspected it.

Will my house catch fire if water got into my meter box?

It can — water inside a meter box causes arcing and short circuits that can ignite surrounding materials, sometimes hours after the storm as moisture tracks through wiring. Leave the meter box closed, do not open or touch it, and book an emergency inspection. Call Sydney Electrical Service on 0433 462 902 if you see corrosion, scorch marks, or smell burning near the box.

How much does it cost to repair a storm-damaged switchboard in Sydney?

Cost varies widely depending on what is damaged — a single blown service fuse is a quick fix, while a water-logged switchboard may need full replacement including new RCDs and circuit breakers. We provide fixed-price quotes before any work begins, so you know exactly what you are up for.

Who should I call first after a storm — an electrician or Ausgrid?

Call Ausgrid (13 13 88) first if the entire street is dark, a power line is down near your property, or your service fuse has blown — those faults are on their network and they must attend first. If your neighbours have power but you do not, the fault is on your side of the meter and an electrician is the right first call.

Do I really need an electrician to check things if the power came back on and everything seems fine?

If circuits tripped during the storm, breakers feel warm to the touch, any outlets spark when you plug something in, or lights flicker on otherwise working circuits, book a post-storm inspection — storm surges can leave heat damage inside wiring that only shows up days later. If nothing tripped and everything behaves normally, you are likely okay, but any doubt is worth a quick check.
