Founded in 1888 by Harvey Hubbell, the eponymous company was the conduit through which the pull-chain lamp socket was originally sold. Hubbell has since grown into an electricity transmission and distribution behemoth, housing more than 75 brands that sell components found on power lines, electrical substations, and within commercial and industrial buildings. The company's primary operations are within the United States, where around 90% of revenue is derived.
