SPT-2 is the same as SP-2 but all-thermoplastic, rated 300 volts, available with or without a third conductor for grounding.
SPT-2, described in relation to SP-2, is the same light-duty lamp cord but in an all-thermoplastic construction, rated at 300 volts and available with or without a third conductor for grounding. Heavier than SPT-1, the thermoplastic build provides durability and moisture resistance, while the optional grounding conductor allows the cord to serve equipment that requires a ground. The parallel form keeps the cord flexible.
By offering a grounding option in a heavier thermoplastic construction, SPT-2 suits light-duty applications needing a ground and a bit more robustness. It remains a light-duty cord for lamps and small equipment.
In commercial and industrial settings, thermoplastic light-duty cords like SPT-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 offering a grounding option in a heavier thermoplastic construction suits light-duty applications needing a ground and a bit more robustness, SPT-2 remains a light-duty cord for lamps and small equipment with the durability of its all-thermoplastic build.
At Windy City Wire, the focus on quality low-voltage cable and cord includes thermoplastic light-duty cord types like SPT-2. Supplying cord with appropriate construction, ratings, and grounding options helps customers match products to light-duty power needs in commercial and industrial settings.
