Extension cords are convenient but can be dangerous if misused. In fact, they account for around 3,300 home fires each year. Keep these safety tips in mind:
"Extension cords can be very helpful in delivering power right where we need it. However, regardless of the gauge or rating of the cord, an extension cord is a temporary solution and is not meant to be used as a long-term extension of your household’s electrical system."
– Electrical Safety Foundation International
To use them safely:
- Choose cords certified by UL, ETL, or CSA.
- Match the cord’s amperage rating to the appliance you’re powering.
- Never run cords under rugs or through walls.
- Replace cords that are damaged or frayed immediately.
- Avoid connecting multiple cords together (daisy-chaining).
These precautions are especially important when dealing with high-demand appliances that require more power.
High-Power Appliance Care
High-power appliances, like refrigerators and dryers, need extra attention to stay safe. They should always be on dedicated circuits and maintained regularly. Here’s how to ensure their safe operation:
