Common Mistakes That Could Increase Your Risk of an Electrical Fire
Extension cords and power strips make it easy to plug in extra devices when you need them. Whether you’re working in the garage, setting up outdoor lighting, or simply trying to reach an outlet across the room, they’re incredibly convenient.
Unfortunately, they’re also one of the most commonly misused electrical products in the home.
Many homeowners don’t realize that extension cords are designed for temporary use, not as a permanent solution. Improper use can lead to overheating, damaged wiring, and even electrical fires.
Here are a few simple ways to use extension cords more safely.
1. Never Use an Extension Cord as Permanent Wiring
If you’ve had the same extension cord plugged in behind a couch, under a desk, or running across a room for months, it’s time to rethink the setup.
Extension cords are intended for temporary situations. If you regularly need power in the same location, having a licensed electrician install an additional outlet is the safer long-term solution. Extension Cord Safety Tips – Electrical Safety Foundation International
2. Avoid Overloading Power Strips
A power strip doesn’t create additional electrical capacity—it simply provides more places to plug things in.
High-wattage appliances such as:
- Space heaters
- Microwaves
- Air fryers
- Refrigerators
- Portable air conditioners
should generally be plugged directly into a properly grounded wall outlet rather than an extension cord or standard power strip.
3. Don’t Run Cords Under Rugs or Furniture
When extension cords are covered by rugs, carpets, or heavy furniture, heat cannot dissipate properly. Over time, the insulation can become damaged without anyone noticing.
Instead, keep cords visible and avoid placing anything heavy on top of them.
4. Inspect Cords Before Using Them
Before plugging in an extension cord, take a quick look for:
- Cracked insulation
- Exposed wires
- Loose plugs
- Burn marks
- Bent prongs
If you notice any damage, replace the cord rather than attempting to repair it.
5. Use Outdoor-Rated Extension Cords Outside
Not all extension cords are designed to withstand moisture and changing weather conditions.
Whenever you’re powering outdoor equipment, holiday lighting, or tools, make sure you’re using an extension cord specifically rated for outdoor use.
6. Know the Warning Signs
If you notice any of the following, it’s a good idea to have your electrical system evaluated:
- Frequently tripping breakers
- Flickering lights
- Warm outlets
- Buzzing sounds
- Burning odors
- Discolored receptacles
These symptoms may indicate overloaded circuits or other electrical issues that should be inspected by a licensed electrician.
