Safe use of extension cords and power strips

Extension cords are handy, but not a permanent solution

Extension cords and power strips are meant for temporary use. If misused, they can overheat or even cause fires. This article provides general tips to avoid that.

Do’s

• Use grounded extension cords where grounded sockets are available.
• Fully unwind cable reels, especially for higher loads.
• Check regularly for damage and replace cords with cracks or kinks in the insulation.

Don’ts

• Do not connect heavy loads (EV chargers, home batteries, space heaters) via standard extension cords.
• Avoid daisy-chaining multiple power strips.
• Do not run cables under carpets or doors where they can be pinched.

Leafy Energy context

• Use solid, properly installed fixed wiring for smart chargers and batteries.
• In the demo we show visual examples of “good” and “bad” setups to train users.
