gauge. An undersized cord will cause a drop in line voltage
resulting in loss of power and overheating. When using
more than one extension to make up the total length,
be sure each individual extension contains at least the
minimum wire size. The following table shows the correct
size to use depending on cord length and nameplate
ampere rating. If in doubt, use the next heavier gauge. The
lower the gauge number, the heavier the cord.
