8 Alarming Signs Your Switchboard Won’t Survive Storm Season

Storm season can be tough on your home’s electrical system. Heavy rain, lightning, strong winds and power fluctuations can place additional pressure on electrical infrastructure, particularly older or poorly maintained switchboards.

Your switchboard is the central control point for your property’s electrical circuits. It distributes electricity throughout the building and houses protective devices designed to respond when something goes wrong. When the switchboard is outdated, damaged or already showing warning signs, severe weather can expose problems that may otherwise remain unnoticed.

The good news is that you don’t need to wait for a storm to discover an electrical issue.

By recognising the warning signs of a switchboard that may not be ready for storm season, you can arrange a professional inspection and address potential problems before they become more serious.

Here are 8 alarming signs your switchboard won’t survive storm season.

1. Your Switchboard Is Old and Outdated

One of the biggest warning signs is simply the age and condition of the switchboard.

Older properties can still have switchboards built around electrical systems designed for a very different level of household demand. Over the years, properties may have gained air conditioning, multiple televisions, computers, kitchen appliances, pool equipment, solar systems, EV chargers and countless other electrical devices.

The switchboard may still appear to work normally, but that doesn’t necessarily mean it is well suited to your property’s current needs.

Older switchboards can also contain ageing components that have deteriorated over time. Exposure to heat, moisture, dust and general wear can affect electrical equipment, particularly where a switchboard has not been professionally inspected or maintained for many years.

Before storm season, it is worth having an older switchboard assessed to determine whether its condition and configuration remain suitable.

2. Fuses Are Still Being Used Instead of Modern Circuit Protection

If your property still relies on old ceramic fuses, that can be an important reason to arrange an electrical inspection.

Traditional fuse systems can operate differently from modern circuit breaker arrangements and may provide less convenience when a fault occurs.

More importantly, the presence of an older fuse board can indicate that the property’s electrical infrastructure has not been substantially upgraded for many years.

A professional electrician can assess whether the existing protection is suitable for the installation and whether additional modern protection should be considered.

Storm season is not the ideal time to discover that your electrical system is overdue for an upgrade.

3. Circuit Breakers Keep Tripping

A circuit breaker that trips occasionally may be responding to a legitimate electrical fault or overload. However, frequent tripping should never be ignored.

If you find yourself constantly resetting the same breaker, there may be an underlying problem involving:

• An overloaded circuit
• A faulty appliance
• Damaged wiring
• A deteriorating connection
• Another electrical fault

Repeatedly resetting a breaker without investigating why it is operating can allow the underlying problem to remain unresolved.

This is particularly important before storm season because faults that are already occurring under normal conditions deserve attention before the electrical system faces additional challenges from severe weather and power disturbances.

If a circuit breaker repeatedly trips, have the cause investigated by a licensed electrician.

4. You Can See Signs of Heat or Burning

Visible heat damage around a switchboard is one of the most serious warning signs.

Look for:

• Brown or black marks
• Discolouration around switches or breakers
• Melted plastic
• Warped components
• Burn marks
• A persistent burning smell

These signs can indicate excessive heat, a damaged component or an electrical connection that requires urgent professional attention.

Electrical equipment should not be opened or investigated by an unqualified person.

If you notice smoke, active burning, significant damage or another immediate hazard, prioritise safety and seek professional assistance.

A switchboard showing signs of heat damage should not simply be left until the next electrical fault occurs.

5. Your Switchboard Has Exposed or Deteriorated Components

Electrical switchboards should provide appropriate protection around internal electrical components.

If you can see damaged sections, deteriorated covers or other components that appear compromised, the installation should be professionally assessed.

A switchboard may deteriorate due to age, physical impact, environmental exposure or previous electrical work.

Storm season can increase the importance of addressing these concerns because water and electrical infrastructure are a dangerous combination.

Rainwater intrusion, flooding or moisture entering an already compromised installation can create additional electrical hazards.

Never touch exposed electrical components yourself, particularly if the switchboard appears wet or damaged.

6. Your Switchboard Is in an Area Vulnerable to Water

Location matters.

A switchboard installed in a garage, external area, basement, utility room or another location exposed to moisture may face greater environmental challenges than one installed in a dry internal area.

This doesn’t automatically mean the switchboard is unsafe. However, it does make the condition of the enclosure, surrounding area and electrical equipment particularly important.

Before storm season, look for obvious signs of water entry, dampness, corrosion or deterioration around the electrical installation.

Don’t attempt to remove covers or investigate internal components.

A qualified electrician can determine whether the installation is appropriately protected and whether any maintenance or corrective work is required.

7. Your Lights Flicker or Power Behaves Erratically

Flickering lights are easy to dismiss, particularly when they happen briefly.

However, recurring flickering, intermittent power problems or unusual electrical behaviour can indicate that something needs to be investigated.

Potential causes can vary considerably. The issue might involve an appliance, a particular circuit, electrical connections or another part of the installation.

The important point is that recurring electrical symptoms shouldn’t simply be accepted as normal.

If your property has experienced flickering lights, unexplained power interruptions or other unusual behaviour, arranging an electrical inspection before storm season can help identify the underlying issue.

It can also give you an opportunity to discuss whether the switchboard and associated electrical infrastructure need upgrading.

8. You Don’t Have Adequate Surge Protection

Storms can be associated with electrical surges and power disturbances, making surge protection an important consideration for some properties.

Modern homes are full of sensitive electronic equipment.

Consider everything connected to your electrical system:

• Televisions
• Computers
• Gaming equipment
• Modems and networking hardware
• Home automation systems
• Security systems
• Appliances
• Smart devices
• Solar and battery equipment

A suitable surge protection strategy can help reduce the risk of transient voltage events affecting connected electrical equipment, depending on the type of protection installed and the nature of the event.

However, surge protection is not a substitute for maintaining the switchboard itself.

Before storm season, it can be worthwhile asking a licensed electrician whether surge protection is appropriate for your property’s electrical installation.

Why Storm Season Can Put Electrical Infrastructure Under Pressure

Storms can introduce several electrical challenges at once.

Lightning can create electrical surges. Strong winds can damage overhead infrastructure and vegetation. Heavy rain can contribute to flooding and moisture-related hazards. Power outages and supply disturbances can also affect properties.

An ageing switchboard may already have weaknesses that become more apparent during these conditions.

This is why preventative electrical maintenance is so valuable.

Rather than waiting for severe weather to reveal a problem, homeowners can have their electrical infrastructure assessed beforehand.

What Should You Check Before Storm Season?

You don’t need to carry out electrical work yourself to prepare your property.

Instead, look for obvious warning signs and arrange professional assistance where appropriate.

Pay attention to whether:

• Your switchboard is particularly old
• Fuses are still being used
• Breakers trip regularly
• There are signs of heat damage
• Electrical components appear damaged
• There is evidence of moisture around the switchboard
• Lights regularly flicker
• Power behaves unpredictably
• You have never had the switchboard professionally assessed
• You’re planning to add major electrical equipment

Even one of these signs can justify arranging an inspection.

Why Switchboard Maintenance Matters Before Storm Season

Preventative electrical maintenance is about finding potential problems while there is still time to address them.

Imagine discovering a deteriorating electrical component during a major storm event. Getting the issue investigated and repaired may be more difficult if severe weather is already affecting local infrastructure.

By contrast, a pre-season electrical inspection provides an opportunity to identify concerns when normal maintenance and repair options are available.

This proactive approach can be particularly valuable for older homes, commercial buildings, strata properties and properties with significant electrical demand.

Can a Switchboard Protect Against Lightning?

It’s important to understand what your switchboard can and cannot do.

A switchboard contains protective devices designed for particular electrical risks, but no switchboard can guarantee protection from every consequence of a lightning strike or major electrical event.

Appropriate surge protection may provide an additional layer of protection against certain transient electrical events, but its effectiveness depends on the installation, equipment and circumstances.

Good electrical protection is therefore about using an appropriate combination of protective measures rather than expecting one device to prevent every possible problem.

A licensed electrician can assess the property and recommend appropriate measures.

Should You Upgrade Your Switchboard Before Summer?

There is no single rule that says every older switchboard needs to be immediately replaced.

The right decision depends on the condition and configuration of the installation, the property’s electrical demand and any future upgrades you are planning.

However, there are several situations where an assessment is particularly worthwhile.

For example, you may be considering a switchboard upgrade if you’re:

• Renovating
• Installing air conditioning
• Installing an EV charger
• Adding solar panels
• Adding battery storage
• Increasing the property’s electrical capacity
• Experiencing repeated circuit faults
• Dealing with an ageing or damaged switchboard

A professional electrical inspection can help you understand whether repair, maintenance or replacement is the most appropriate option.

Preparing Older Homes for Storm Season

Older homes deserve particular attention because their electrical infrastructure may have been designed before modern appliances and technology became standard.

A property built decades ago may now have significantly greater electrical demand than when it was first constructed.

At the same time, components can naturally age.

This doesn’t mean every older home is dangerous. It does mean that preventative inspections become increasingly valuable as electrical installations age.

A qualified electrician can assess the condition of the switchboard and relevant electrical infrastructure and identify areas requiring attention.

Don’t Wait for a Storm to Expose the Problem

Electrical problems often give you warning signs before they become major faults.

A breaker may trip repeatedly. Lights may flicker. Components may become discoloured. You may notice an unusual smell or discover that the switchboard is clearly showing its age.

These aren’t problems to ignore simply because the electricity is currently working.

Storm season adds another reason to take those warning signs seriously.

The safest approach is to have electrical concerns professionally assessed before severe weather arrives.
