There are many different types of extension cords available on the market, and it can be hard to know which one to buy. Here’s a guide to determining which extension cord is right for you.
Large tools and appliances need to receive plenty of power. A regular outlet isn’t enough; you have to use an extension cord with the right electric current. Longer cords tend to have lower amp capacities, so if you need a lot of amps, it’s best to opt for a shorter cord.
Wire gauge is also important to make sure there is enough room for power to flow through the cord. An undersized cord not only makes it more difficult to power a tool but also poses safety risks. When a substantial electric current runs through a cord that is too small, the cord can overheat, and the insulation can melt.
Taking these factors into consideration, a 100-foot long, 12-gauge extension cord is ideal for most work.
Once you’ve chosen your cord, be sure to practice proper safety precautions. Unroll the cord completely when it is in use. Don’t use a cord that is not properly rated for your tool or has a missing or broken ground plug. And finally, don’t use the same plug for multiple high-current tools or appliances at the same time.
