What is a 18 AWG extension cord?

Gauge is a numerical rating of copper wire diameter and is identified by an American Wire Gauge (AWG) number. For this reason, long extension cords have a lower capacity than shorter cords of the same AWG size. For example, an 18 AWG cord may only be rated for 5 to 7 amperes (amps) of load at a length of up to 25 feet.Click to see full answer. Also, what does AWG mean on an extension cord? American Wire Gauge how do I know what gauge my extension cord is? Typically, you can find a cord’s gauge rating printed on the cord jacket. If you’re replacing an old cord, look for the AWG number printed on the jacket, and select a new cord with the same gauge. To determine the cord’s capacity, consider the cord length along with the wire gauge. Similarly, how many amps can 18 gauge wire handle? 16 amps Which is better 12 gauge or 14 gauge extension cord?14-Gauge Cords: Any 14-gauge cord between 0 and 50 feet long will adequately handle loads between 10 and 15 amps. 12-Gauge Cords: If your tool load is between 10 and 15 amps and the length of the cord is 50 to 100 feet, you need a 12-gauge cord to safely power any tool. This is a great extension cord for many purposes.
