Summer in Launceston brings longer days, warmer temperatures, and more time spent at home or entertaining outdoors. It also places extra demand on your home’s electrical system. Increased use of air conditioners, heat pumps in cooling mode, ceiling fans, and outdoor power can significantly raise household electrical load. Combined with summer storms and lightning activity, this creates a higher risk of overloads, outages, and electrical hazards if systems aren’t prepared.
As a long-established, family-owned electrical business with deep roots in Northern Tasmania, read the Mance Electrical story and local history, the team at Mance Electrical has spent generations helping local homes stay safe through every season. These summer electrical safety tips are designed to help Launceston homeowners reduce risk, improve efficiency, and know when to call a licensed electrician.

What changes in summer that affects your electrics?
Heatwaves increase household electrical load.
During summer, cooling appliances often run for extended periods. Air conditioners and heat pumps draw high startup current, especially during peak heat. When multiple high-wattage appliances operate on the same circuit, the risk of circuit overload increases. This is why many homeowners experience breakers tripping more often during heatwaves.
You may also notice lights flickering when the air conditioner turns on. This typically indicates a temporary voltage drop caused by a high inrush current, particularly if the circuit is already near capacity.
If your home is relying heavily on cooling, it may be worth checking whether your system is running efficiently, filters, airflow, correct thermostat setpoint. For households upgrading or installing a more efficient unit, our team can help with heat pump installation for Launceston homes.
Higher temperatures stress electrical components.
Electrical systems operate less efficiently when ambient temperatures rise. Wiring, switchboards, and outlets can heat up faster under load. Homes with older switchboards or limited circuit capacity are especially vulnerable during prolonged hot weather.
Summer storms introduce surge risk.
Thunderstorms can cause lightning-related power surges that travel through the electricity network. These surges can damage sensitive electronics unless proper surge protection is in place. Summer electrical safety isn’t just about load management, it’s also about storm preparedness.
Quick safety checklist (5-minute scan)
This Launceston summer electrical checklist helps identify common risks quickly:
- Test your safety switch (RCD)
You should test your safety switch every three months. Press the test button on your switchboard, it should trip immediately. If it doesn’t, the RCD may not protect against electric shock and should be inspected. Homes without modern protection should consider switchboard upgrades, testing, and maintenance for safer homes. - Check cooling appliances for efficiency
Clean air conditioner filters and ensure outdoor units are clear of debris. A clean system uses less energy, reduces kWh usage, and places less strain on circuits. Set thermostats sensibly, extreme low setpoints increase peak load without improving comfort. - Inspect power boards and outlets
Feel outlets and power boards while appliances are running. Warm plugs, discolouration, or a burning smell are signs of overload. You must not overload power boards, particularly with high-wattage cooling appliances. - Review extension lead use (especially outdoors)
Extension leads should only be used temporarily. Outdoors, they must be weather-rated and kept dry. If outdoor power is used regularly for BBQ lighting or garden equipment, fixed outlets are a safer long-term solution. - Prepare for storms (simple storm surge checklist)
Identify sensitive electronics you can unplug during severe weather. Check surge protector indicator lights to ensure they’re still functional.

Power boards & extension leads: what to avoid
Overloaded power boards increase fire risk.
Power boards are designed for low to moderate loads. Plugging multiple high-draw appliances into one board, or into a double adaptor, significantly increases the risk of overheating and electrical fire.
You must not:
- Daisy-chain power boards or extension leads
- Plug portable air conditioners into power boards
- Cover power boards or place them in enclosed spaces
- Run extension leads under rugs, through doorways, or where they can be pinched
If a breaker trips repeatedly, then reduce the load immediately and arrange an inspection. Persistent tripping is a warning sign, not an inconvenience. If you need urgent help, contact our emergency electricians in Launceston for fast fault finding.
For workplaces, or home offices with lots of equipment plugged in, routine safety checks also matter, particularly when devices are added for summer operations. Our team provides test and tag services in Launceston for appliance safety compliance.
Storms & surges: what surge protection does (and doesn’t)
Surge protection reduces damage from lightning-related surges, but it has limits.
Surge protectors:
- Absorb transient voltage spikes
- Protect electronics from indirect lightning and grid switching
- Reduce appliance damage during minor surge events
They do not:
- Prevent blackouts
- Replace safety switches (RCDs)
- Guarantee protection from a direct lightning strike
- Last forever (they degrade over time)
For stronger protection, many Launceston homes benefit from surge protection integrated at the switchboard. This can be assessed during professional switchboard testing and safety upgrades, especially ahead of storm season.
For added prevention, you can also consider proactive fault detection with thermal imaging inspections to identify hot spots in circuits, particularly useful when heatwave circuit load is pushing older connections harder than usual.
When to call an electrician (red flags)
You should contact a licensed electrician if you notice:
- Repeated circuit breaker trips, especially during hot days
- Warm, buzzing, or discoloured outlets
- Burning smells or crackling sounds
- Frequent flickering lights under normal load
- Heavy reliance on power boards due to insufficient outlets
- No visible safety switches in the switchboard
If something feels urgent, especially burning smells or visible damage, don’t wait, reach out to our 24/7 emergency electrician team in Launceston.
For non-urgent improvements and preventative upgrades, you can review our full range of electrical services for homes and property owners or get in touch via the Mance Electrical contact page.
