Flexible Portable Cord (Service Cord)

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:

• Type SJOOW - 300 VAC, 18 to 10 AWG
• Type SOOW - 600 VAC, 18 to 10 AWG
• Type SJEOOW - 300 VAC, 18 to 10 AWG
• Type SEOOW - 600 VAC, 18 to 10 AWG
• Type W Cable - 2000 VAC, 8 AWG

What are the main differences between SOOW, SJOOW, SEOOW and SJEOOW?

• SOOW and SJOOW have a thermoset rubber jacket
  • Best abrasion resistance
  • Rubber, unlike plastic, is resistant to melting on momentary contact with a hot surface
  • Lowest cost
• SEOOW and SJEOOW have a thermoplastic elastomer jacket
  • Wider continuous temperature range
  • Better flexibility at very low temperatures
• The J stands for Junior and carries a 300V voltage rating; the "non-J" cord rating is 600V.

Commonly used UL and CSA designations for flexible cable power cord include:

• S = Severe Service (600 volt cords)
• SJ = Junior Severe Service (300 volt cords)
• E = Elastomer
• OO = Oil-Resistant Outer Jacket and Oil-Resistant Interior Insulation
• W = Weather and Water resistant (not the same W designation as the UL Type W Portable Cord also available)
