Safe and Effective Power Strip Usage Tips
Even the best power strip can pose risks if not used correctly. Adhering to safety guidelines is paramount to protect your home and devices.
1. Never “Daisy Chain” Power Strips or Extension Cords
This is arguably the most critical safety rule. Connecting one power strip to another, or plugging a power strip into an extension cord, creates a significant fire hazard by overloading the circuit. The National Fire Protection Association (NFPA) strictly prohibits this practice. Each power strip should always be plugged directly into a permanently installed wall outlet.
2. Avoid Overloading the Power Strip
Every power strip has a maximum wattage or amperage rating. Never exceed this limit by plugging in too many high-power devices. Overloading can cause the strip to overheat, leading to melted cords, short circuits, and fires. Always calculate the total wattage of all devices you intend to use with the strip.
3. Do Not Plug High-Wattage Appliances into Power Strips
Appliances with heating elements or motors draw a significant amount of power and should always be plugged directly into a wall outlet. These include:
- Space heaters
- Microwaves
- Toasters
- Refrigerators
- Hair dryers
- Coffee makers
- Washing machines and dryers
These devices are designed for dedicated wall outlets and can quickly overload a power strip, even a surge protector, causing it to overheat or trip the circuit breaker.
4. Ensure Proper Placement
Keep power strips in well-ventilated areas, away from anything that could easily catch fire, such as curtains, carpets, or paper. Avoid placing them under rugs or furniture, as this can trap heat and make it difficult to spot signs of damage or overheating.
5. Avoid Wet or Damp Locations
Unless specifically rated as a GFCI-protected (Ground Fault Circuit Interrupter) outdoor or bathroom power strip, never use power strips in wet or damp environments like kitchens, bathrooms, or laundry rooms. Water and electricity are a dangerous combination.
6. Regularly Inspect for Damage
Periodically check your power strips and their cords for any signs of wear and tear. Look for:
- Frayed wires
- Cracked or discolored casings
- Loose outlets
- Burn marks or melted plastic
- An unusual burning smell or warmth
If you notice any of these issues, discontinue use immediately and replace the power strip.
7. Use for Temporary Purposes
Both power strips and extension cords are designed for temporary use and should not serve as a permanent substitute for proper electrical wiring. If you consistently find yourself needing more outlets in a specific area, consider having additional wall outlets installed by a qualified electrician.
