Hubbell received at least 45 patents,[3] most of which were for electric products. The pull-chain electrical light socket was patented in 1896, and his most famous invention, the U.S. electrical power plug, in 1904. It allowed the adoption in the U.S. of convenient, portable electrical devices, which Great Britain had enjoyed since the early 1880s.[4] In 1916, Hubbell was also granted a patent for a three-bladed power plug, including a ground prong, which Australian regulators and electrical accessory manufacturers adopted as the standard for that country in the 1930s. It was also adopted in New Zealand, Argentina, and (with a minor variation) in China.[5]
