Plugging in your favorite devices and appliances can seem like a simple task, but it can turn dangerous if you don’t know what not to plug into a power strip. 27% of electrical fires are caused by improper use of extension cords and power strips. Safeguard yourself and your home with these important tips.^^
1. Refrigerators
Refrigerators are indispensable in any household. However, they don’t belong in a power strip. The heavy load drawn as they cycle on and off can lead to overheating and fire hazards. Power strips aren’t built for high-wattage appliances, so always plug your refrigerator directly into a dedicated wall outlet. This ensures reliable operation and reduces the risk of disaster.
2. Microwaves
Microwaves pull exceptional amounts of power, often exceeding 1,000 watts during usage. This sudden demand can easily overheat a power strip, making them a significant fire risk. Choose a wall outlet for your microwave instead. Both large and small units are best avoided when it comes to power strips.
3. Space Heaters
Leading contributors to electrical fires, space heaters require much energy—often over 1,500 watts. Connecting one to a power strip can melt plastic or trip breakers. Given their high heat output, manufacturers issue warnings against using space heaters with power strips. Always plug them directly into a grounded wall outlet and supervise them closely when in use.
4. Air Conditioners
Much like refrigerators, air conditioners have a significant power demand. Their power surges at start-up can overload a power strip, possibly leading to fires or failing appliances. Regardless of the model—large window units or smaller portable options—air conditioners should always be plugged into wall outlets with their own circuit.
5. Hair Dryers and Flat Irons
Hair dryers, curling irons, and flat irons heat up rapidly and draw considerable current, putting them at risk for overloading a power strip. They spike electricity when turned on and can also cause damage over time. Seeing that outlets may be scarce in bathrooms, use a wall outlet near your mirror and avoid any risk of water exposure. Don’t forget to unplug your tools after you’re done to save energy and avoid potential hazards.
6. Toasters and Coffee Makers
Toasters and coffee makers may appear harmless but require ample power for their heating elements. This can strain power strips significantly, especially when used simultaneously. Always utilize a wall outlet instead of a shared power source for these devices. If you find that you’re running short on outlets, carefully rotate your devices rather than overloading one strip.
7. Washers and Dryers
Both washers and dryers use high electrical loads, needing a dedicated 240-volt outlet—much more than a power strip can support. Using a strip can pose serious risks, such as damaging the appliance or even causing an electrical fire. When dealing with major appliances, it’s best to consult an electrician for proper installations if you don’t already have the necessary outlets.
8. Sump Pumps
To safeguard your home from flooding, sump pumps require uninterrupted power. If a power strip stops working during a storm, your pump will fail, potentially causing extensive water damage. Additionally, moisture around electrical components can lead to shorts or corrosion. Always connect sump pumps to a grounded wall outlet and consider installing a battery backup system.
9. Medical Equipment
Devices such as CPAP machines and oxygen generators need constant, reliable power. Plugging them into a power strip can create a dangerous point of failure. If the strip goes out or trips, the device shuts down, which can be life-threatening. Always opt to connect these sorts of medical devices directly into a grounded outlet, making sure to clearly label it to prevent accidental unplugging.
10. Power Tools and Shop Equipment
Electric tools in the workshop can often cause power spikes when they start. Saws, drills, and other power equipment require direct connection to properly grounded outlets. While heavy-duty power strips designed for workshops exist, these should only be used if rated for such use, and it’s crucial to avoid using multiple tools simultaneously from one outlet.
11. Extension Cords
Daisy chaining power strips with extension cords is a particularly dangerous practice. As each cord adds electrical resistance, the potential for increased heat builds up, which could eventually lead to overheating and fire. Trust instead in a single, longer heavy-duty cord rated for your appliance or have a licensed electrician install more outlets where you need them.
The Dangers of Overloading Power Strips
Power strips can support a maximum of 1,800 watts total, but many appliances utilize more on their own. Overloading a strip causes it to heat, damaging its internal wiring, which compromises safety. Never cover power strips with rugs or furniture, as they need air circulation to dissipate heat effectively. If any strip feels hot to the touch, detach it immediately and reassess your usage.
How to Use Power Strips Safely
Select power strips with built-in surge protection, and always look for UL or ETL certification. Limit use to one high-wattage device at a time, and avoid placing strips in damp areas like bathrooms to reduce the risk of short circuits. Unplug power strips when not in use, and obviously replace any damaged strips right away. Stay within the limits of your devices for optimal safety.
When It’s Time to Upgrade
Constantly needing more outlets signifies it may be time for an upgrade. A licensed electrician can assess your needs and install new outlets or circuits, reducing the risk associated with overloading existing ones. Don’t fall into the trap of adding more power strips, as every connection increases fire risks. Investing in a safer electrical setup pays off in preventing future disasters.
Final Thoughts
Awareness of what not to plug into a power strip is essential. Use wall outlets for high-demand appliances, while reserving strips for lower-wattage devices like chargers and lamps. Regularly check that cords remain visible and undamaged, and always unplug them when not in use. Educating yourself on safe practices can go a long way in preventing accidents and keeping your home safe.
