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. Table A shows
the 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.
