One of our mentors got a job at Wago as the sales rep. for the midwest.
I think he is working on getting discounts for teams in the midwest or something like that. I love their cage clamp technology!!
You will never have a loose wire again. The plastic with crack before the wire slips. I have abused these connectors in any way I can think of, the wire does not pull out if inserted properly.
Check out their Levernuts if you get a chance. They are like wirenuts but a lot easier to use(for me anyways) and more secure.
