Portable cord (also called service cord) is a cable with multiple conductors used for electrical power connections requiring flexibility. These multi-conductor power cables can be used both indoors and outdoors. Typical applications include wiring for industrial machinery, large appliances, heavy duty tools, motors, and temporary electrical power and lighting for construction sites.
Five types of industrial multi-conductor flexible cords are available from AutomationDirect:
