A: No need to crimp these wires together, if you'd like though you can pretwist the wires together and then place the connector on and twist it tight. Hope this helps!
A: I believe so. I can't be absolutely certain but did see an electrician use them to repair underground wires that went to a lift station.
A: I would say yes, they are the same as other wire nuts but they are filled with silicone so make sure you push the wires all the way in. As you twist the silicone will come out and make a seal.
A: Hey Dave, I reached out to you in an email, but these are rating for 600V Max so they should work with your application. Hope this helps!
