Pre-Storm Electrical Checklist for Sydney Homeowners

How do you prepare your electrical system when a storm warning is issued? With a 20 minute visual check of the parts most exposed to water and surges: the switchboard, meter box, outdoor power points, visible cabling, safety switches and any backup power gear. Look, test the safety switch buttons, and photograph anything suspicious, but do not open the board or touch wiring. This is the on the day check; the bigger pre-season jobs live in our storm season prep guide.

⚡ Quick Answers: pre-storm checks

• What can I safely check myself? Anything you can inspect with your eyes, plus the TEST button on safety switches. Nothing that involves opening enclosures or touching wiring.
• What am I looking for? Burn marks, rust, moisture, cracked covers, perished seals, sagging wires and breakers that already trip. Any of those means call an electrician before the weather arrives.
• Does testing safety switches really matter? Yes. A safety switch that fails its test gives you no shock protection on that circuit, exactly when moisture faults are most likely.
• What about my generator? Check fuel, condition and that you know how the changeover works before the outage, not during it.
• Who do I call if I find something bad? Something dangerous right now: 000, then emergency make safe. Concerning but stable: book an electrician today rather than joining the post storm queue.

1. Safety rules before you start

This checklist is visual only. Do not open the switchboard cover, test live power points, or touch exposed or corroded wiring. If at any point you smell burning, see scorch marks or blackening, spot loose copper, or find water inside the board or meter box, stop and call us; those signs outrank everything below.

2. The switchboard: five minutes

Find the board and look it over. Burn marks or discolouration around it point to arcing. Note whether any breakers or safety switches are already sitting tripped, and whether anything has been tripping in the days before the warning, because existing faults get worse when the water arrives. Look for moisture, condensation or rust in and around the enclosure, and check the door actually closes and seals.

An old board that fails this eyeball test is not going to improve mid storm. That is a switchboard upgrade conversation, ideally before summer, and if the board takes on water during the event itself, our wet switchboard guide covers why it must stay off afterwards.

3. Meter box and outdoor power points: five minutes

The meter box and outdoor outlets are the weather's first targets. At the meter box, look for water pooling at the base, cracks in the housing, rust or pitting, and vegetation or debris blocking ventilation. At outdoor power points, look for cracked or loose covers, discolouration, corrosion, and any sign water has been inside. Outlets that have sat unused for years can be corroded internally even when the outside looks fine.

These entry points are also where storm surges ride into the house. Plug in powerboards protect only what hangs off them; a whole house surge protection device at the switchboard protects everything, and our surge protection guide explains the difference. Damage to the meter box itself sits on the network side of the installation and is Level 2 ASP work to repair.

4. Visible cabling and power points inside: five minutes

Walk the visible cable runs: garage, carport, under the eaves, along fences to sheds and pools. Look for cracked or frayed insulation, UV brittle sheathing, rodent damage and sagging or unsupported runs. Inside, glance at power point plates for scorch marks and looseness. Overhead, check your service line for sagging or branches resting on it, and if anything about the line or your private pole looks wrong, treat it as urgent: our guides to pole warning signs and vegetation responsibility cover who fixes what. Damaged cabling is a fire and shock hazard: do not touch it, call for make safe support.

5. Test every safety switch: five minutes

Each safety switch has a TEST button, and pressing it is completely safe. Press each one: the switch should trip immediately and its circuits should go dead. Reset and move on. Count how many you have, note any that refuse to trip, and get failures looked at urgently, because a failed safety switch means no shock protection where you need it most. Homes built before the early 1990s may have circuits with no safety switch at all, which is worth fixing before the season rather than after the first wet weekend of rain related tripping.

6. Backup power, if you have it (or wish you did)

Generator owners: check fuel level and age, look the unit over for corrosion, and confirm the transfer switch is accessible and you know how it operates. An automatic transfer switch does the swap itself in under 75 seconds; a manual setup only works if you remember the sequence in the dark.

If you have no backup and outages hurt at your place, note it for after the storm. A properly installed standby generator is a planned project, and our generator load calculator is the two minute starting point.

7. Found something? Three pathways

Immediate danger, meaning sparks, burning smells, active water on electrical gear or exposed live wires: call 000 if life or property is at risk, then our emergency make safe line. Urgent but stable, meaning tripping breakers, burnt outlets, damaged cabling or a rusted meter box: book a repair now, while electricians still have availability. Just want certainty: book an electrical safety inspection and get the whole system checked and documented before the season peaks. Take photos either way; they help your electrician and your insurer, and our after storm guide covers the claim side if damage does get through.

How High Demand Electrical helps

We turn this checklist into a professional service: pre-storm safety inspections with a written report, safety switch testing and retrofits, whole house surge protection installation, weatherproofing and board upgrades, and backup power installation. As Level 2 ASPs we also cover the meter box, service line and consumer mains, so one visit covers both sides of the installation, and our make safe team runs 24/7 when the storm wins anyway.

Pre-Storm Checklist FAQs (Sydney)

How often should I run this check?

Whenever a severe weather warning is issued, plus once at the start of each storm season. Coastal homes, where salt accelerates corrosion, benefit from more frequent looks at outdoor gear.

Can I test surge protection myself?

No. Surge devices need professional testing to confirm they are still protective, and many are one shot devices that look fine after they have already sacrificed themselves.

Are safety switches compulsory?

They have been required on new circuits for decades, so older homes often have partial coverage. If parts of your board have no safety switch, a retrofit is one of the cheapest safety upgrades available.

How long does a professional pre-storm inspection take?

Usually one to two hours for a house, covering the board, safety switch trip testing, outlets, visible wiring and the external service equipment, with a written report at the end.
