USE PROPER EXTENSION CORD. 9.
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
