History of the Marrette® Brand

The brandname Marrette and wire connectors have been interchangeable since Bill Marr revolutionized the way conductors were connected with the invention of the first pressure-type wire connector in 1914. Today, Marrette® wire connectors are still an industry standard and are still proudly designed and manufactured in Canada by ABB.
