Switchboard Health Checks

Protect Your Home, Your Appliances, and Your Insurance Claim

Power surges are more common than most homeowners realise, and the damage they cause isn’t always immediately obvious. A surge can silently degrade your electronics, shorten the life of your appliances, or take out your switchboard in a single event.
At Electrx, we install residential surge protection systems that shield your home from electrical spikes, brownout recovery surges, and the kind of quiet cumulative damage that adds up over time. Whether you’re protecting a fully renovated home in Williamstown or a growing household in Point Cook with solar and an EV charger, we’ll recommend the right level of protection for your setup.

What Is a Power Surge and Why Does It Happen?

A power surge is a sudden spike in voltage that pushes more electricity through your home’s wiring than it’s designed to handle. Even a brief surge lasting a fraction of a second can overload circuits, damage appliance circuit boards, or silently degrade electronics over time.
Common surge causes in Melbourne’s western suburbs include:

  • Lightning strikes during summer storms
  • Power returning suddenly after a Powercor outage or blackout
  • Fallen trees or accidents damaging local network infrastructure
  • Grid switching events during maintenance or emergency restoration
  • High-draw appliances: air conditioners, solar inverters, EV chargers — causing internal surges
  • Shared infrastructure in apartment blocks or estate substations under load

If you’ve recently experienced a lightning storm, blackout, or suspected surge event and want your home inspected, we can provide a post-surge assessment and written report ,useful for home and contents insurance claims.

Surge Protection + Home Insurance: What Homeowners Should Know

Most home and contents policies will cover appliance damage from a defined surge or lightning event — but the claim outcome can depend on whether reasonable protection was in place.

Insurers are increasingly asking whether surge protection was installed, particularly for higher-value claims involving multiple appliances or electronics. A switchboard surge diverter provides both genuine protection and documented evidence that your home was appropriately protected at the time of the event.

If a surge has already occurred and you’re looking to make a claim, a licensed electrician’s post-surge inspection report from Electrx can support your documentation, confirming what happened, what was affected, and what protection was or is now in place.

Types of Surge Protection for Homes

We install surge protection to match how you use power — from single high-risk rooms to whole-home coverage.

1. Switchboard Surge Diverters (SPDs)

Whole-home protection — the most effective solution
Installed directly into your home’s switchboard, an SPD blocks dangerous voltage spikes before they can reach your circuits. Everything downstream is protected — fridges, TVs, air conditioners, EV chargers, solar inverters, and more.

After absorbing a major surge event, the device may need replacing. That’s not a failure — it means the protection worked, and your equipment survived.

Best for: homes in storm-exposed areas, properties with solar or EV charging, older homes being updated, anyone wanting comprehensive protection.

2. In-Wall Surge-Protected Power Points (GPOs)

Targeted protection for high-risk rooms
Installed by a licensed electrician, these look identical to standard power points but include built-in surge protection. Ideal for home offices, media rooms, kitchens, and anywhere expensive equipment stays permanently plugged in.

A clean, permanent solution, no powerboards, no visible protection devices, just a standard-looking outlet doing more behind the scenes.

3. Portable Surge-Protected Powerboards

Fast, accessible protection for renters or targeted use

A practical starting point for renters or for protecting specific equipment quickly. Suitable for computers, home entertainment systems, and routers. Should be replaced after absorbing a major surge rather than reused.

Brownouts: The Other Risk Worth Understanding

Brownouts are drops in voltage rather than spikes.
They are a separate but related hazard and they can during periods of high grid demand ( often happens in summer when air conditioning useage is high) and it puts significant strain on motors and electronics, particularly fridges, fans, washing machines, and smart home devices.
The real danger often comes when power is restored after a brownout. The surge that follows as the grid recovers can be more damaging than a lightning-induced spike. A properly installed SPD protects your home from both ends — the drop and the recovery spike.

Do You Need Surge Protection at Home?

You probably do if any of the following apply:

  • You’ve lost appliances or electronics to a previous storm or grid event
  • You have solar panels, a battery system, or an EV charger at home
  • Your home has expensive electronics, a home theatre, or smart home automation
  • You live in a suburb that has experienced outages or grid instability
  • You’re renovating, updating your switchboard, or upgrading your electrical system
  • You want your home and contents insurance claim to be as strong as possible if a surge event occurs

What Surge Protection Won’t Do and What Comes Next

No surge protection system is a guarantee against all electrical damage. A catastrophic direct lightning strike can overwhelm any protection device. What a properly installed SPD does is dramatically reduce the risk of damage in the vast majority of real-world surge events, and gives you documented evidence of protection for insurance purposes.

After any significant event, we recommend an inspection:

  • To assess whether the SPD absorbed damage and needs replacing
  • To identify any wiring or circuit issues the event may have exposed
  • To provide a written report if you’re making an insurance claim

Surge Protection for Modern Homes

If you have solar panels, a home battery, or an EV charger, surge protection takes on added importance. These systems involve large amounts of power flowing in multiple directions through your switchboard — and they’re expensive to replace.

We install surge protection as part of new solar and EV charging setups, and we can retrofit SPDs to existing systems. If your solar installer didn’t include switchboard-level surge protection, it’s worth addressing.

Residential Surge Protection Across Melbourne’s Western Suburbs

Based in Brooklyn, we service homes across the full spread of Melbourne’s western suburbs — including Altona, Footscray, Sunshine, Yarraville, Williamstown, Werribee, Hoppers Crossing, Point Cook, Tarneit, Truganina, Laverton, Newport, and West Melbourne.

We know the Powercor network across the region, and we know which areas have experienced outage and surge events in recent years. That local knowledge informs the protection solutions we recommend.

Residential Surge Protection FAQs

More than most people realise. You don’t need to be in a lightning-prone rural area to be at risk. Grid switching events, brownout recovery spikes, and appliance-generated surges happen in suburban Melbourne regularly. If you have solar, an EV charger, or expensive electronics, the cost of an SPD is small compared to what you’re protecting.

It can strengthen your claim significantly. Insurers increasingly ask whether surge protection was in place, particularly for multi-appliance or high-value claims. A switchboard SPD is documented evidence that your home was appropriately protected. If a surge event has already occurred and you’re making a claim, we can provide a written post-surge inspection report to support your documentation.

A switchboard SPD protects the whole house by blocking voltage spikes at the point of entry — before they reach any circuits. A plug-in surge protector only protects the devices plugged directly into it, and varies significantly in quality and capacity. For whole-home protection, the switchboard SPD is the right solution. Both have a place — we often recommend a combination.

After a major event, yes — the device may have absorbed damage doing its job. This is by design. A surge diverter sacrifices itself to protect your equipment. We’ll inspect after any event and replace the device if needed, providing a record of the inspection and replacement that can support an insurance claim.

Plug-in surge powerboards are available to renters immediately. In-wall GPO protection is possible with landlord approval. Switchboard-level protection requires landlord or property manager sign-off — but it’s worth asking, because it protects the building and their assets too. We can liaise with your property manager on your behalf if needed.

A switchboard surge diverter for a standard home typically ranges from $350–$700 installed, depending on your switchboard configuration. In-wall GPOs are priced per point. We’ll assess your home and provide a written quote — call 0447 139 493 to book.

Don’t ignore it. Post-blackout recovery surges are a real risk, and strange appliance behaviour in the days following an outage can indicate surge damage. Call us for an inspection, we can assess your switchboard, circuits, and affected equipment, and provide a written report if you need to make a claim
