Extension Cords
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.
