What To Look for in an Extension Cord
Shopping for an extension cord isn’t the most complex task, but there are still a few things to keep in mind. If you want to be sure to find the cable that matches your needs, here’s what you need to look for.
The first thing you need to look for is what size wire the extension cord uses, referred to as its “gauge” or “AWG.” A wire’s gauge is its diameter, and the lower the gauge, the higher its diameter. A lower gauge extension cord is a good fit for heavy duty devices that draw a lot of power. Whereas high gauge extension cords are a better fit for smaller household devices.
Hand in hand with gauge, pay close attention to the level of current an extension cord is rated to carry, which is usually listed in amperage and wattage. Before choosing an extension cord, be sure to check the electricity needs of the device you intend to power. Never try to overpower your extension cord. If it’s rated for 10 amps, stick to that. Over taxing an extension cord can cause the cord to fail or even cause a fire. It’s always a good idea to get a little more than what you need than cutting it too close.
Likewise, think of every place you may need to use this extension cord and choose the type that matches your needs. Many are rated for both indoor and outdoor use, which usually means they offer water resistance, but don’t count on that. Read the descriptions and don’t push any electrical cord beyond its intended purpose.
Finally, no matter what you intend to use it for, remember that extension cords are temporary solutions. A well-made cord will last many years but is no replacement for a dedicated outlet. If you plan on keeping the device you’re powering in its position, it’s often a wiser idea to pay a professional to place an outlet in a convenient position, both for aesthetics and long-term safety.
