You got it. Here is the history of the Canadian invention - MarretteOriginally Posted by ToUtahNow
At the turn of the twentieth century, a young Scotsman
named Bill P. Marr immigrated to Ontario, Canada. After
settling in the Toronto area, Marr was soon employed by the
T. Eaton Company as a contractor for Ontario Hydro, where
he worked as an electrician converting gas lit homes to
electrical incandescent lighting.
As part of this conversion, the accepted practice back then
was a process called " solder and tape" Typically, a mechanic
would first run the wires required, then an electrician would
polish the exposed conductors and twist them together. Next,
the ends of the wires would be firmly joined by dipping them in
a pot of molten solder, and after they cooled, the wires would
then be wrapped with an insulating tape.
Over time, this process proved to be both time consuming and
dangerous, as Bill Marr discovered first-hand when he
inadvertently spilled a scorching solder pot while working in a
customer’ home. Convinced that there had to be a safer and
more efficient way of joining two electrical conductors, Marr
worked tirelessly in his basement shop until he finally invented
the first pressure type wire connector (a set screw version which
was the forerunner to the modern day wire connector).
Since that day in 1914, the Marr® company has become a
leading manufacturer of twist-on wire connectors in North
America. The Marrette® brand has so revolutionized the way
branch circuits were connected that the term "marrette" has
become synonymous with " wire connector" in the electrician’s
And since being acquired by T&B in 1997, this highly respected
Marrette® brand name has become an integral part of the vast
Thomas & Betts product offering to the construction market.
