factors which cannot be built into this product, but must be supplied by the operator. Extension Cords 1. As the distance from the supply outlet increases, you must use a heavier gauge extension cord. Using extension cords with inadequately sized wire causes a serious drop in voltage, resulting in loss of power and possible tool damage. (See Table A.) 2. The smaller the gauge number of the wire, the greater the capacity of the cord.
RECOMMENDED MINIMUM WIRE GAUGE FOR EXTENSION CORDS* (120/240 VOLT) (at full load) 50’ 75’ 100’ 150’ EXTENSION CORD LENGTH 25’ NAMEPLATE AMPERES 0 – 2.0 18 18 18 18 16 2.1 – 3.4 18 18 18 16 14 3.5 – 5.0 18 18 16 14 12 5.1 – 7.0 18 16 14 12 12 7.1 – 12.0 18 14 12 10 - 12.1 – 16.0 14 12 10 - - 16.1 – 20.0 12 10 - - - TABLE A * Based on limiting the line voltage drop to five volts at 150% of the rated amperes.
