8. Extension Cords
Do not use reeled or coiled cable. Reeled or coiled cable can produce a counter EMF (electromotive force). The counter EMF can
reduce the current carrying capability of an extension cord. This counter EMF will result in a voltage drop within the motor
instigating a thermal overload condition. Power supply must handle wattage requirements. When conditions require the use of
reeled cable, unreel all cable and place on the ground in very loose overlapping non-uniform coils.
