Does the length of an extension cord affect the power?

Extension cord lengths determine the cord’s power capacity. Every extra foot of cord increases the electrical resistance. This decreases the power the cord can deliver to connected devices. For best results, use the shortest extension cord possible.

Do extension cords have a limit?

In general, extension cords should not exceed 100 feet in length. However, by plugging one extension cord into another, the maximum cord length can be easily exceeded. If the job requires more than a 100-foot distance, a temporary power distribution box is required.
