What is the Maximum Extension Cord Length? However, it can also be used in 110v/120v outlets to operate some low-rating devices.
It can run your garage’s power tools such as table saw, compressor, or even electric lawnmowers. Typically, a 10/3 extension cord is sufficient to energize 220v/240v rated equipment. Lengths of Cord and Maximum Wattage Limits at 110V Then, we can talk about how many watts, amps, and volts a 10 gauge extension cord can handle without getting damaged. Typically, as the wire length increases, its resistance also increases, which may result in a higher percentage of voltage drop, which may also cause the wire to overheat.įirst, let me give you some examples using the watts rating chart below, where the capacity of an extension cord is reduced depending on its length. However, the current rating of an extension cord might depend on its length. Such loads may come from a generator, compressor, tools such as a table saw, and other high-power machinery. Therefore, size is the primary factor you need to consider when buying an extension cord.įor example, a 10 gauge electrical cord is commonly used for high loads. Generally, the thicker the wire, the higher the watts and amp rating it can hold.
How Many Watts can a 10 GA Extension Cord Draw?īefore jumping into the topic, it is good to understand first that the size of the wire determines the wattage and amperage it can hold.
