Electrical Requirements
The use of an improper extension cord could result in a risk of fire or electric
shock.
The use of long extension cords should be minimized. If an extension cord is used, ensure that it has
three conductors with a ground and that the wire size and length meet electrical code for the voltages
and currents of the Electrical Specifications table. Locate all cords so that they will not be driven over,
stepped on, tripped over, or otherwise subjected to damage or stress.
Refer to the
