The American Wire Gauge System (AWG) rates the amount of current an extension cord can safely transmit based on the gauge (thickness) of the wire--the larger the wire, the smaller the AWG number. For instance, a 12 AWG wire is larger than a 14 AWG wire and can power tools and appliances with higher wattage ratings. The AWG rating is especially important with longer cords, since the power-carrying capacity decreases with length. This super heavy-duty UL-listed 10 AWG cord provides the highest-wattage capacity available for your most demanding requirements and conducts the power through 100% oxygen-free copper. Since extension cords are less expensive than replacing tools or appliances ruined by operating at incorrect wattage levels, bigger is almost always better when it comes to power extension cords. An OUTSTANDING value in a top-quality, contractor-grade tool.
