7.2 Extension Cords
The use of extension cords is discouraged. Try to
position machines within reach of the power source.
If an extension cord must be used, make sure it is
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.
Table 2 shows 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.
