16. USE PROPER EXTENSION CORD.
Make sure your extension cord is in good condition. When using an extension
cord, be sure to sue 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. A 50 foot extension cord must be at least 12 gauges in
diameter, and a 100 foot extension cord must be at least 10 gauges in diameter. If
in doubt, use the next heavier gauge. The smaller the gauge number, the heavier
the cord.
