One of his most important industrial inventions, still in use today, is the thread rolling machine. He quickly began selling his newly devised manufacturing equipment alongside his commercial products. Hubbell received at least 45 patents, [3] most of which were for electric products. The pull-chain electrical light socket was patented in 1896 ...
Hubbell's first design was a socket which screwed into a lampholder (like the early lampholder plugs), but with a separable plug with pins (U.S. patent 774,250) or blades (US patent 774251). The 1906 Hubbell catalog [4] shows the blade plug with a flush mounting socket for use in wall or floor. Other manufacturers adopted the Hubbell pattern ...
NEMA 1-15P (two-pole, no ground) and NEMA 5-15P (two-pole with ground pin) plugs are used on common domestic electrical equipment, and NEMA 5-15R is the standard 15-ampere electric receptacle (outlet) found in the United States, and under relevant national standards, in Canada (CSA C22.2 No. 42 [1]), Mexico (NMX-J-163-ANCE) and Japan (JIS C 8303).

“The short answer, we think, is related to avian influenza,” said Caitlinn Hubbell, market research analyst at Purdue University’s Center for Food Demand Analysis and Sustainability in West ...
The devices are named using the format NEMA n-mmX, where n is an identifier for the configuration of pins and blades, mm is the maximum current rating, and X is either P for plug or R for receptacle. For example, NEMA 5-15R is a configuration type 5 receptacle supporting 15 A. Corresponding P and R versions are designed to be mated. Within the ...
The National Electrical Manufacturers Association (NEMA) [5] is the largest trade association of electrical equipment manufacturers in the United States. [6] Founded in 1926, it advocates for the industry and publishes standards for electrical products. Notably, the form of US household electrical outlets and plugs is specified by NEMA.
The North American Charging System (NACS), standardized as SAE J3400, is an electric vehicle (EV) charging connector standard maintained by SAE International. [1] Developed by Tesla, Inc., it has been used by all North American market Tesla vehicles since 2021 and was opened for use by other manufacturers in November 2022.
