How Can You Protect Your Home’s Electrical System Before A Storm?
Preparation is your best defence against storm damage. By taking the right steps ahead of time, you can reduce risks and keep your electrical system safe.
Get Your Electrical System Checked By A Licensed Electrician
One of the most effective ways to protect your home is to arrange an inspection by a licensed electrician. This inspection will identify any existing issues that may become hazards during a storm.
- What they check: An electrician will look for damaged or outdated wiring, worn components, and unsafe connections.
- Why it matters: Faulty wiring or old switchboards can fail when stressed by storms, causing power outages or fires.
- When to do it: Arrange this well before storm season to ensure you have time for repairs.
Install Surge Protection Devices
Lightning and power surges from storms can damage your electrical wiring and appliances.
- Whole-of-home surge protection: Installed at your switchboard, this device absorbs sudden spikes in electrical current, preventing damage to your entire electrical system.
- Plug-in surge protectors: These protect individual appliances, like computers or TVs.
- Benefits: Surge protectors help avoid costly appliance damage and reduce the risk of electrical fires caused by surges.
Secure Outdoor Electrical Equipment
Storms often bring strong winds, damaging outdoor electrical devices such as air conditioners, solar panels, and antennae.
- What to do: Ensure all outdoor equipment is securely fastened to prevent movement or detachment.
- Why it helps: Loose equipment can be damaged or cause electrical faults if knocked around or blown off by wind.
- Tip: Check mounting brackets, screws, and wiring for wear or looseness regularly.
Raise Electrical Outlets And Appliances In Flood-Prone Areas
If your home is in an area prone to flooding, it is wise to raise your power points and electrical appliances above likely flood levels.
- How it protects: Elevating outlets keeps water from electrical wiring and equipment, significantly reducing the risk of electrical faults and shocks.
- Additional advice: Consider installing waterproof covers for outdoor outlets.
Trim Trees And Clear Debris Near Electrical Wiring
Falling branches can damage power lines or your home’s external wiring, creating hazards during storms.
- What to do: Regularly trim branches that overhang or are close to power lines and your home’s electrical system.
- Why: Removing dead or weak branches prevents them from breaking and causing faults during high winds.
- Safety note: Only qualified professionals should trim branches near power lines.
What Should You Do During A Storm To Protect Your Electrical System?
When a storm hits, taking the right actions can prevent damage to your electrical system and keep you safe.
Turn Off And Unplug Electrical Appliances
One of the simplest but most effective things you can do is to turn off and unplug your electrical appliances.
- Why: Power surges caused by lightning or grid fluctuations can damage plugged-in devices.
- Which appliances: Computers, televisions, kitchen appliances, and other sensitive or expensive electronics should be unplugged.
- Extra caution: Don’t forget chargers, lamps, and other small devices.
Switch Off The Main Power Supply If It Is Safe To Do So
If flooding occurs or if you notice damage to electrical wiring, switch off the main power at the switchboard—but only if you can access it safely.
- Why switch off: Turning off the power reduces the risk of electric shocks and prevents damage to your wiring.
- Safety first: If water is near the switchboard or you feel unsafe, do not attempt to switch off power yourself. Call a professional.
Avoid Using Electrical Equipment If Wet Or Standing In Water
Never use electrical appliances or touch outlets if they are wet or standing in water.
- Risk: Water conducts electricity and increases the risk of electric shock.
- Tip: If you suspect flooding has reached electrical points, avoid contact and await inspection.
Use Battery-Powered Lighting Instead Of Candles
During power outages, use torches or battery-operated lamps.
- Why not candles: Open flames can cause fires if knocked over or unattended.
- Battery-powered options: These are safer and provide reliable light.
What Should You Do After A Storm To Ensure Your Electrical System Is Safe?
Once the storm has passed, it is essential to carefully check your electrical system before restoring it for everyday use.
Avoid Using Electrical Equipment That Has Been Exposed To Water
Do not turn on or use any electrical appliance or switch that has come into contact with water until it has been inspected and declared safe.
- Why: Water can cause hidden damage that might result in electrical faults or shocks.
- If unsure, avoid using it and get professional advice.
Contact A Licensed Electrician To Inspect Your Home’s Electrical System
A professional inspection is vital after a storm to ensure your system is safe.
- What they check: Wiring, outlets, switchboards, and appliances for damage.
- Why: Only a qualified electrician can safely repair electrical faults and confirm the system is safe.
- Do not attempt: Avoid DIY repairs, as incorrect fixes can cause fire or shock hazards.
Report Power Outages Or Electrical Damage To Your Electricity Provider
Contact your electricity supplier immediately if you notice power outages, damaged poles, or downed power lines.
- Why: They need to fix infrastructure faults and ensure the safety of the wider network.
- Safety tip: Stay clear of any downed or damaged power lines.
Keep Away From Downed Power Lines
Never touch or approach fallen power lines, even if they appear inactive.
- Danger: Downed lines may still carry electricity and cause serious injury or death.
- Action: Call emergency services or your power company to report the hazard.
Conclusion
Protecting your home’s electrical system during storms requires careful preparation, safe actions, and professional inspections afterwards.
Simple but effective measures such as having your electrical system inspected, installing surge protectors, securing outdoor equipment, and switching off power safely can significantly reduce the risk of damage and keep your family safe.
Always prioritise safety. If you are unsure about electrical issues, contact a licensed electrician rather than attempting repairs yourself.
Frequently Asked Questions
Why Is It Important To Install Surge Protectors Before A Storm?
Surge protectors help prevent damage caused by sudden electrical spikes, which are common during lightning storms.
Installing a whole-of-home surge protector at the switchboard offers the best protection for your entire electrical system. Without surge protection, appliances and wiring can be seriously damaged, leading to costly repairs.
Can I Turn Off My Main Power Supply During A Storm If There Is Flooding?
Turning off the main power supply can reduce the risk of electric shock and prevent damage if flooding or electrical faults occur.
However, only do this if it is safe to access your switchboard without coming into contact with water. If you are unsure or if water is near the switchboard, call a licensed electrician for help.
What Should I Do If I See Downed Power Lines After A Storm?
Never approach or touch downed power lines as they may still be live and extremely dangerous. Keep a safe distance and immediately report the downed lines to your electricity provider or emergency services.
Stay indoors and warn others nearby to avoid the area until professionals arrive to fix the problem.
