to determine the cord's capacity, it's important to consider the cord length along with the wire gauge. Every extra foot of cord increases the electrical resistance, which decreases the power the cord can deliver to connected devices (The longer the cord the lower the gauge to push the power from end to end.) Because of this, it's best to use a cord that is only as ling as you need. For example, it's inefficient to use a 100-foot cord to power a device that only needs to extend 40 feet from an outlet. We always recommend using 100 feet or less and never plug multiple extension cords into each other. For a 14.5 amp tool a 25-75 foot cord needs to be 14 gauges or lower. A 100 foot cord needs to be 12 gauges.
