Can a surge damage my LED downlights?

Yes — and it's increasingly common. LED drivers contain delicate switching electronics that fail under surge. The downlight may still emit some light but flicker, buzz, or run hot. Replace damaged units and check whether the drivers are integral or remote.

My modem keeps "almost working." Could it be a surge?

Likely. Surges often leave devices in a degraded state — booting but unstable, dropping connections, overheating. Replacement is usually the only fix because internal damage is microscopic.

We had a brief power blink and now nothing works. Is that a surge?

A power blink is a switching event — the network briefly disconnects and reconnects. Reconnection often produces a surge. Damage from these "blinks" is one of our most common Sydney callouts after summer thunderstorms.

How quickly can you assess surge damage?

We respond 24/7 for active emergencies and within 24–48 hours for damage assessment. Call 0433 462 902 to book.

Is it safe to keep using my appliances after a suspected power surge?

Not necessarily — surge-damaged appliances can develop internal faults that create a fire or shock risk even if they still appear to work. Hardwired devices like ovens, ducted air conditioners, and dishwashers should be checked by a licensed electrician before continued use if you suspect a surge has run through your home.

What's the difference between a surge protector power board and whole-house surge protection?

A surge protector power board guards only the devices plugged directly into it and can be overwhelmed by a large nearby lightning strike; whole-house surge protection is installed at your switchboard and clamps incoming surges before they reach any circuit in the home, giving every hardwired appliance and outlet a first layer of defence.

How much does it cost to install whole-home surge protection in Sydney?

Cost varies depending on your switchboard type and the protection devices required for your setup, so the right answer is a fixed-price quote. Call 0433 462 902 to book an assessment and we'll price it on the spot.

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

Call Ausgrid (13 13 88) if the street supply is still out or a pole or line is visibly damaged — restoring the network is their responsibility. For damage inside your home to appliances, circuits, or your switchboard, call a licensed electrician; both calls can happen at the same time.

Will my house catch fire if a surge damaged the wiring or an appliance?

A surge can compromise insulation and internal components in hardwired appliances in ways that create a slow-burn fire risk that isn't immediately obvious. If you smell burning plastic, hear buzzing from an outlet or the switchboard, or a breaker keeps tripping after a storm, isolate that circuit and have it inspected before using it again.

Sutherland Shire combines coastal pockets, bushland fringes, and dense suburban family-home zones, each with characteristic electrical patterns. Switchboard vintages span 50+ years across the region with substantial 1980s and 1990s renovation history overlaid on original installations.

Down in the Shire near the bay, salt exposure quietly wears on outdoor switchboards and surge gear before a spike even lands. After a surge through a family home we check what's been damaged, make it safe for the household, and fit protection that holds up to the coastal conditions.

⚠ Stop — Call Immediately if You Notice Any of These:

A surge-damaged appliance that "still works" may have degraded internal insulation
A burnt-out smoke alarm cannot warn you of fire
A failed surge protector cannot protect against the next surge
A damaged but operating microwave can leak microwave radiation
An AC compressor with damaged windings can short to earth and trip RCDs at random
A solar inverter fault may indicate a DC isolator or string fault that is still hot
Burning smell from any appliance
Smoke from a wall outlet, switchboard, or fixed appliance
A TV, oven, or dishwasher that is hot when off
Repeated tripping of an RCD on the surge-affected circuit
Buzzing or flickering lights that didn't behave that way before

About Power Surge Damage – What to Do Next

Power surges are caused by lightning during Sydney’s summer thunderstorms, Ausgrid network switching after outages, and large local loads — welders, motors, air conditioners — cycling on shared neighbourhood transformers. A surge can incinerate unprotected electronics in microseconds — if devices have stopped working after a storm or a brief power blink, call 0433 462 902 or book a post-surge inspection.

TVs, modems, oven control boards, alarm systems, garage door openers, air conditioners, and pool controllers are the devices most commonly killed. The next priority is identifying everything that may be quietly damaged before it fails completely — Sydney Electrical Service dispatches 24/7 across every metropolitan suburb.

What to Do Right Now in Sutherland

Make a list of every electronic device that stopped working or behaves strangely after the surge.
Unplug damaged devices to prevent further upstream effects.
Check your switchboard for tripped breakers or RCDs and reset once if needed.
Inspect the switchboard for the surge protector — most modern devices have a green/red status window. Red means it's done its job and is now spent.
Check the solar inverter display for fault codes and screenshot any error messages.
Photograph all damage — including device serial numbers and burn marks if visible.
Save the data for insurance — many home and contents policies cover surge damage but require itemised proof.
Don't replace damaged items immediately until the surge protection is repaired or upgraded — a repeat surge will destroy the new gear too.

Electrical work in Sutherland

Sutherland grew up around its 1885 railway station, so the housing stock is a real mix: interwar and Federation-era cottages closer to the centre, a big base of post-war fibro and brick-veneer homes from the 1950s and 60s through the surrounding streets, and a growing band of medium-density unit blocks and strata developments around the station precinct and the Kingsway. Plenty of those older homes are still running tired switchboards with rewireable ceramic fuses and no RCDs, along with original two-wire wiring that's well past its rewire date once it starts feeding modern loads.

Sutherland sits in the Ausgrid network, so any new connection, consumer-mains upgrade, point-of-attachment repair or service-fuse work is Level 2 ASP territory. We handle switchboard upgrades with proper safety switches, three-phase supply for larger renovated homes, ducted air and EV chargers, plus common-property switchboard work for the strata blocks near the line. Licensed, accredited and available 24/7.

Common Questions

How do I know if my surge protector did its job or if it's now broken?

Most modern Type 2 SPDs (surge protective devices) have a status window — green means functional, red means the device has absorbed energy and reached end of life. A red status means the device must be replaced before the next surge event.

Will my insurance cover surge damage?

Most Australian home and contents policies cover power surge damage to specified items, often with a sub-limit per claim. Requirements vary, but you'll typically need: an itemised list of damaged equipment, photos, original purchase receipts where possible, and a licensed electrician's report. We provide insurance-grade reports as standard.

Can a surge damage my switchboard itself?

Yes. A major surge can degrade busbars, breakers, and surge diverters. After any significant surge event we recommend a switchboard inspection — often the only reliable test is insulation-resistance and thermal imaging.

Is a power board with surge protection enough?

No. Plug-in surge protectors are useful for individual devices but they only protect what's plugged into them, and many older ones have already absorbed surges they don't show. Whole-of-installation Type 2 SPDs at the switchboard are the proper protection.

Why Sutherland Residents Choose Us

Bushland-fringe surge damage is a consistent issue in Engadine, Heathcote, and Yarrawarrah — overhead supply through tree canopy is more exposed to lightning and tree-branch faults than urban underground supply, and surge-protection failures are common.
