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.

Western Sydney homes — post-war brick veneers across Bankstown and Liverpool, Federation cottages through Parramatta and Auburn, modern estate builds from Penrith to Pennant Hills — span a 70-year vintage range with switchboard ages and conditions to match.

Across Western Sydney you've got post-war fibro and brick-veneer alongside new master-planned estates, and surges hit both, frying appliances in older homes and tripping three-phase gear in big modern builds. We assess single or three-phase damage and fit surge protection sized to the property.

⚠ 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 Granville

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 Granville

Granville has an industrial and rail heritage that shows in its building stock: tightly packed Federation and inter-war workers' cottages, Art Deco and post-war brick flats, old warehouse and light-industrial buildings now being converted, and a fast-growing band of new strata apartments near the station and Parramatta Road. It's a suburb where heritage homes, small business and high-density living all sit side by side, each with very different electrical demands.

On the older cottages we regularly find ageing two-wire wiring and fuse boards that need RCDs and, often, a full rewire. Commercial and converted spaces tend to need three-phase supply and distribution upgrades. Across Endeavour Energy's network we handle the Level 2 work these jobs depend on: consumer mains, network connections and disconnections, point-of-attachment, metering and supply upgrades, plus strata switchboard repairs for the unit blocks. One licensed crew (236351C) for it all, 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.
