More than 3,300 home fires start from power strips and extension cords each year. While these convenient devices help us power our increasingly connected lives, many of us are unknowingly creating serious safety hazards. Understanding these common mistakes could prevent a devastating electrical fire in your home.
Daisy chaining multiple power strips together
One of the most dangerous yet common mistakes is “daisy chaining” – plugging one power strip into another. This practice violates electrical codes and creates a serious fire hazard. When multiple strips are connected, the first strip ends up supplying far more outlets than it’s designed to handle.
The interconnected setup increases electrical resistance, generating excess heat. This heat buildup becomes particularly dangerous when the strips are hidden under furniture or carpets. Even if you’re using high-quality power strips, daisy chaining negates their built-in safety features.
Plugging high-power appliances into standard strips
Many homeowners don’t realize that standard power strips aren’t designed to handle large appliances. Devices like refrigerators, microwaves, space heaters, and air conditioners require dedicated circuits due to their high power draw.
These appliances need significant current during startup, which can overwhelm a typical power strip. Even if the strip seems to work initially, the sustained high current draw can cause internal components to fail. This failure often happens without warning and can result in sparking or melting.
Using indoor power strips in outdoor settings
Standard indoor power strips lack weatherproofing and shouldn’t be used outside. Moisture exposure can create dangerous short circuits and electrical shock risks. Even on a covered porch, humidity and temperature changes can damage internal components.
If you need outdoor power, invest in properly rated outdoor strips with weather-resistant covers and GFCI protection. These specialized units are designed to withstand environmental challenges while maintaining safety standards.
Hiding power strips under rugs or furniture
Concealing power strips might improve aesthetics, but it creates serious safety risks. Power strips need proper airflow to dissipate heat. When covered by carpets, furniture, or curtains, they can overheat rapidly.
Additionally, hidden strips are more likely to sustain physical damage from foot traffic or furniture movement. This damage might go unnoticed until a serious problem develops. Keep power strips visible and accessible for regular inspection.
Ignoring signs of power strip damage
Warning signs often appear before a power strip fails completely. Hot spots, burn marks, melted plastic, loose connections, or buzzing sounds indicate immediate replacement is needed. Continuing to use damaged strips significantly increases fire risks.
What if you smell something burning but can’t locate the source? Assume it’s an electrical issue and inspect all power strips immediately. One failing component can compromise an entire electrical system.
Mixing surge protectors with basic power strips
Not all power strips offer surge protection. Basic power strips provide no defense against power surges that can damage expensive electronics. Many people mistakenly believe any power strip will protect their devices.
Invest in proper surge protectors for sensitive electronics like computers, gaming systems, and home theater equipment. Standard power strips should only be used for basic items like lamps or phone chargers.
Remember: power strips aren’t permanent solutions for insufficient outlets. If you regularly need more power points, consult an electrician about installing additional wall outlets. This investment in your home’s electrical infrastructure will provide safer, more reliable power for years to come.
