When winter hits in Louisville and Southern Indiana, your home’s electrical system works harder, heaters run longer, lights stay on earlier, and extra devices (holiday décor, space heaters, sump pumps, generators) get added to the mix. Use this winter electrical safety checklist to help prevent tripped breakers, damaged equipment, and fire hazards, while keeping your family comfortable all season.
If you spot anything concerning, Laswell Electric is here to help. Call 502-373-4538 to schedule service.
Quick Winter Electrical Safety Checklist
1) Test your smoke and carbon monoxide alarms
Winter means more heaters, fireplaces, and closed-up homes. Make sure alarms are working and placed correctly.
- Test every alarm monthly
- Replace batteries if needed
- Replace alarms that are past their lifespan (check the back label)
2) Check your electrical panel for warning signs
Your breaker panel is the “heart” of your home’s electrical system, winter is a great time to confirm it’s safe and ready.
Look for:
- Warm panel cover
- Buzzing or crackling sounds
- Breakers that trip repeatedly
- Rust, moisture, or staining near the panel
If any of these show up, it’s time for a professional inspection.
3) Use space heaters safely
Space heaters are one of the biggest winter electrical risks. If you use one, keep it safe:
- Plug directly into a wall outlet (never a power strip)
- Keep at least 3 feet of clearance around it
- Don’t run the cord under rugs or furniture
- Turn it off when you leave the room or go to sleep
If your heater is tripping breakers, that can be a sign the circuit is overloaded or undersized.
4) Avoid overloaded outlets and power strips
Winter adds extra load: humidifiers, heating pads, electric blankets, holiday lights, and more.
- Don’t daisy-chain power strips
- Use a quality surge protector for electronics
- If you need multiple high-draw devices in one area, consider adding a new dedicated circuit
5) Inspect cords, plugs, and outlets
Cold weather doesn’t directly damage wiring inside walls, but it can expose issues with older devices and cords.
Replace or repair:
- Frayed or cracked cords
- Loose plugs that fall out of outlets
- Outlets that spark, feel warm, or smell “burnt”. These are common signs of a failing connection.
6) Be smart with holiday lights (inside and out)
Holiday lighting looks great, just keep it safe.
- Use indoor-rated lights only inside, outdoor-rated only outside
- Don’t staple or nail through cords
- Keep outdoor connections off the ground and protected from water
- Use a GFCI-protected outlet for exterior lighting
- Set lights on timers instead of leaving them on overnight
7) Keep exterior outlets and GFCIs working
Winter moisture (snow, sleet, freezing rain) can create shock hazards outdoors.
- Test GFCI outlets monthly (press Test then Reset)
- Replace broken outlet covers
- Don’t use damaged extension cords outside
If your outdoor outlets trip constantly, we can troubleshoot the cause.
8) Protect your home from power surges
Winter storms can bring outages and power fluctuations.
- Use surge protectors for TVs, routers, and computers
- Consider a whole-home surge protector for broader protection
- If lights flicker frequently, it may be more than a “storm issue”—it could be a loose connection that needs attention
9) Know the signs you should call an electrician
Don’t ignore these red flags, especially during winter when electrical demand is higher:
- Frequent breaker trips
- Dimming or flickering lights when appliances run
- Burning smell from outlets or the panel
- Hot outlets or switches
- Tingling sensation when touching an appliance or metal fixture
If you notice any of these, stop using the affected device/circuit and call a licensed electrician.
10) Generator safety (if you use one)
If you have a portable generator during outages:
- Never run it in a garage, basement, or near open windows
- Use heavy-duty cords rated for the load
- Don’t backfeed your panel without a proper transfer switch
Want a safer setup? Ask about a manual transfer switch or standby generator installation.
