Extension Cord

Use extension cord if needed. The cord must have a three-prong, grounding plug and a three-hole recep- tacle. Make sure cord is in good shape. It must be heavy enough to carry the current needed.An under- sized cord will cause a drop in line voltage. This will result in loss of power and overheating. Use a No. 16 AWG cord for lengths less than 50 feet.
