This UL Approved 250V NEMA 5-15P to NEMA 14-50P Power Cord is a high-voltage power supply solution designed specifically for charging station scenarios. With "UL safety certification + 250V high-voltage capacity + accurate adaptation of dual NEMA interfaces", it has become a core power supply accessory for new energy vehicle home charging stations and commercial charging terminals. It perfectly solves the problems of low charging efficiency or safety hazards caused by insufficient voltage and incompatible interfaces of traditional cables. It strictly complies with UL 62 and UL 943 safety standards and has passed multiple rigorous tests including insulation strength, temperature resistance, and overload protection. The UL certification mark ensures the product is used in compliance with regulations in North America, providing reliable safety guarantees for charging scenarios.
The interface combination has strong adaptability: the input end adopts a standard NEMA 5-15P 3-pin US plug, which can be inserted into common 125V/250V universal sockets for home or commercial use, with wide compatibility and no need for separate modification of power supply lines; the output end is a NEMA 14-50P 4-pin plug, designed specifically for high-voltage charging equipment, supporting 250V single-phase power supply. It can stably connect to new energy vehicle charging station hosts, high-power charging guns and other equipment, meeting the requirements of 32A rated current and 8000W power (such as home fast charging scenarios for Tesla, BYD and other models). There is no fluctuation in current transmission, avoiding charging interruptions or equipment damage caused by poor interface contact.
The 250V high-voltage bearing capacity is a core advantage: compared with conventional 125V cables, this power cord uses a 10AWG (wire diameter 5.26mm²) high-purity multi-strand oxygen-free copper conductor, with excellent electrical conductivity and a low resistance of 0.003Ω/m. There is little heat loss during current transmission. Even when bearing 32A full-load current for a long time, the surface temperature of the cable will not exceed 40℃, avoiding the risk of insulation aging or short circuit caused by overheating. The outer layer is covered with a thickened oil-resistant and flame-retardant PVC sheath with a thickness of 1.5mm, which has the characteristics of UV resistance and resistance to extreme temperatures from -40℃ to 90℃. It can work normally in outdoor charging stations under exposure, rain splashing or low-temperature environments, and its service life is much longer than ordinary cables.
The detailed design fits the needs of charging scenarios: the default length of the cable is 4.5 meters (customizable from 3 to 10 meters). The 4.5-meter length can not only meet the regular distance between the charging station host and the socket but also avoid the risk of tangling or dragging due to excessive length. The connection between the plug and the cable adopts an integrated injection molding reinforcement process, which can withstand a 10kg tensile test, preventing cable falling off caused by long-term plugging or dragging. The surface is printed with clear marks of "UL LISTED", "250V~32A" and "NEMA 5-15P/NEMA 14-50P", facilitating installers to quickly identify specifications and polarity and improve construction efficiency. Whether it is daily power supply for home new energy vehicle charging stations or bulk deployment of commercial charging terminals, this UL Approved 250V NEMA Interface Power Cord can provide stable and efficient power support for charging station scenarios with the advantages of "high safety + high power + high adaptability".
