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:
What are the main differences between SOOW, SJOOW, SEOOW and SJEOOW?
Commonly used UL and CSA designations for flexible cable power cord include:
Flexible Power Cable / Hard Service Cord
5-Conductor Flexible Portable Cord
(SOOW & SEOOW - 16, 14, 12, 10 gauge)
thermoset rubber jacket, 300 VAC
Abrasion resistance, resistant to melting on momentary contact, low cost
Type SJOOW flexible portable cord starts at $0.30 (20 ft. length)
thermoset rubber jacket, 600 VAC
Also meets requirements for 600V "Extra-Hard" use
Type SOOW flexible portable cord starts at $0.32 (20 ft. length)
thermoplastic elastomer jacket, 300 VAC
Wider temperature range, better flexibility at low temperatures
Type SJEOOW flexible portable cord starts at $0.31 (20 ft. length)
thermoplastic elastomer jacket, 600 VAC
Type SEOOW cord is ideal for the same flex applications as Type SJEOOW, but requiring higher voltages.
Type SEOOW flexible portable cord starts at $0.34 (20 ft. length)
Type W Cord
Typical applications for Type W cords include industrial and light- to medium-duty mining cable applications; heavy-duty service as power supply cable; AC systems (grounded and ungrounded); mobile and portable electrical equipment; motor and battery leads.
Type W flexible portable cord starts at $3.92 (10 ft. length)
