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.
