Portable cord

The cord can be employed in a range of applications, such as operating motors in small and large tools, equipment, power extensions, home appliances, and machinery.

Some are used on job sites where resistance to oil, chemicals, and abrasion is essential in extreme environments – both the heat and the cold, outside or inside.

Portable cords are commonly used in a range of facilities, such as construction sites, mills, mines, sports complexes, or even marinas.

Thermoset cords have heavy-duty-grade rubber jackets, are extremely sturdy and oil-resistant, and may remain flexible over a temperature range of −40 to 220 °F (−40 to 104 °C).

[1][3] In the United States, letter codes have been defined by Underwriters Labs (UL) to describe various attributes and ratings of portable cords.
