A, SJOW-A, SJTW-A. or SJTOW-A. Make sure your extension cord is in good condition. When using an extension cord, be sure to use one heavy enough to carry the current your product will draw. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. The table shows the correct size to use depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord. If the extension will be used outside, the cord must be suitable for outdoor work. The letters “WA” on the cord jacket indicate that the cord is suitable for outdoor use.
