• EXTENSION CORDS. 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
following table shows the correct size to use depending on cord length and nameplate ampere
rating. If in doubt, use the next heavier gage. The smaller the gage number, the heavier the cord.
