Extension Cord
Use extension cord if needed. The cord must
have a three-prong, grounding plug and a
three-hole receptacle. Make sure cord is in
good shape. It must be heavy enough to carry
the current needed. An undersized 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.
