English 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. Minimum Gauge for Cord Sets Volts Total Length of Cord in Feet (meters) 120 V 25 (7.6) 50 (15.2) 100 (30.5) 150 (45.7) 240 V 50 (15.2) 100 (30.5) 200 (61.0) 300 (91.4) Ampere Rating More Not Than More American Wire Gauge Than 0 6 18 16 16 14 6 10 18 16 14 12 10 12 16 16 14 12 12 16 14 12 Not Recommended The label on your tool may include the following symbols.
