17. Extensioncords. Makesure your extensioncord isin good condition. When
using an extensioncord, be sure
to use one heavyenough to carry the current
your productwilldraw. An undersizedcordwill cause a drop in linevoltage
resulting in
loss of powerandoverheating. Table 1 showsthe correct size to
use dependingon cord length and nameplateampere rating. If in doubt, use
the nextheavier gauge. The smaller the gauge number, the heavierthe cord.
