SP-1 is a 300 volt, all-rubber, parallel two-conductor lamp cord, a light-duty cord used for lamps and small appliances.
SP-1 designates a light-duty lamp cord rated at 300 volts, built as an all-rubber, parallel two-conductor construction. The two rubber-insulated conductors run side by side in a parallel form that is easy to separate at the ends for termination, and the all-rubber build provides flexibility for light service. SP-1 is used for lamps, small appliances, and similar light-duty applications where flexibility and easy handling matter.
As a light-duty cord, SP-1 is not intended for hard mechanical usage but rather for the modest demands of lamps and small devices. The parallel construction keeps the cord thin and flexible, suiting it to routing and connection in light applications.
In commercial and industrial settings, light-duty lamp cords like SP-1 serve lamps and small equipment within their rating. Recognizing the designation is part of identifying cord suited to light-duty use.
Because the parallel construction keeps the cord thin and flexible, SP-1 suits routing and connection in light applications such as lamps and small appliances, where flexibility and easy handling matter more than the ruggedness a hard-service cord would provide.
At Windy City Wire, the focus on quality low-voltage cable and cord includes light-duty lamp cord types like SP-1. Supplying cord with appropriate construction and ratings helps customers match products to light-duty power needs in commercial and industrial settings.
