This 6 AWG copper building wire is a high-capacity electrical conductor with multiple ratings—RHH, RHW-2, and USE-2—designed for residential, commercial, and industrial applications. It is suitable for both wet and dry locations, with a 90°C maximum operating temperature in either environment. The USE-2 rating makes it ideal for direct burial and underground service entrance applications. With a 600V rating, this wire is commonly used in lighting, power distribution, photovoltaic connections, raceways, and aerial installations. The annealed soft copper conductor provides excellent conductivity and flexibility.
