Whether you’re powering heavy machinery or just making sure your phone is charged, there’s probably a good chance you have more than a few extension cords and power strips around the house. And while you might not have put too much thought into the extension cords since you first plugged them in, you probably should. That’s because different cords are rated for different loads. Despite built-in protections, overloading a power strip or extension cord can potentially result in fire. That’s why if you’re using an extension cord to power any appliances or devices that draw a lot of power, you’ll have to make sure that you’re using the right cord for the job.
All wiring is categorized by gauges, and the gauge of your extension cord is arguably the most important factor to consider. Any cords or wires in the US are rated using the AWG, or the American Wire Gauge system. A smaller gauge number makes for a thicker wire, and thicker wires are more capable of powering larger appliances or machines. You also want to consider the length of the wire. The longer the wire, the greater the voltage drop. That means that in general, if you’re using a long extension cord, you’ll need to choose one with a lower gauge than you would for a short cord.
