SP-2 is the same as SP-1 but of heavier construction, rated 300 volts, available with or without a third conductor for grounding purposes.
SP-2, described in relation to SP-1, is the same general lamp cord but of heavier construction, rated at 300 volts and available with or without a third conductor for grounding. The heavier build provides added durability over SP-1, and the optional grounding conductor allows the cord to serve equipment that requires a ground connection. This makes SP-2 a more capable light-duty cord.
By offering a grounding option and heavier construction, SP-2 extends the light-duty cord family to applications needing a ground or a bit more robustness. The all-rubber, parallel form retains the flexibility expected of a lamp cord.
In commercial and industrial settings, light-duty cords like SP-2 serve lamps and small equipment, including those needing a ground, within their rating. Recognizing the designation and its options is part of identifying cord suited to the application.
Because the heavier build and optional grounding conductor extend the light-duty cord family, SP-2 serves applications needing a ground or a bit more robustness, with the all-rubber, parallel form retaining the flexibility expected of a lamp cord.
At Windy City Wire, the focus on quality low-voltage cable and cord includes light-duty cord types like SP-2. Supplying cord with appropriate construction, ratings, and grounding options helps customers match products to light-duty power needs in commercial and industrial settings.
