One factor that is important is how long of an electric cord you will need because the longer the cord you use, the larger gauge you must use. With an electric trimmer that uses a 25-foot cord, you only need an 18-gauge cord. With a 50-foot cord, you need a 16-gauge cord. At 100 feet of cord length, you need a 14-gauge cord, and, if you use a 200-foot extension cord, you need a 12-gauge cord. The gauge of the cord refers to how thick it is. All cords will say on their package their gauge size.
