Get the overload-protected extension cords.

Yes, and you should buy them.

Extension cords with built-in circuit breakers (or overload protection) exist at any hardware store, usually just called “breaker cords” or “safety cords.” They look normal but have a fat lump near the plug end — that’s the breaker. If you pull too many amps, it trips instead of melting the cord or starting a fire.

Are they recommended? Absolutely, especially for shop tools, space heaters, or any high-draw device. A standard extension cord will just get hot and fail silently. A breaker cord gives you a second chance: it pops, you reset it, and you know you’re overloading that circuit. It’s a cheap insurance policy.

Don’t confuse a surge protector power strip (for electronics) with a circuit-breaker extension cord (for high-amperage loads). Different tools, same idea: don’t skip it.

The $5 more is the best money you’ll spend on extension cords all year.
