• An extension cord must have adequate wire size
(AWG or American Wire Gauge) for safety. The smaller
the gauge number of the wire, the greater the capacity
of the cable, that is, 16 gauge has more capacity than 18
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.

Be sure your power supply agrees with the nameplate
marking. Voltage decrease of more than 10% will cause loss
of power and overheating.
