There was a rep handing them out at the ECF meeting but I haven't used them enough to have an opinion. They seem to cost almost 4 times what a wire nut costs so you have to ask how much labor they save.
I was trying to come up with the legal scenario about why you would need to pass a splice through a KO myself. They show a made up box with the pigtails sticking out implying you just terminate the wires, snap in the the RX connector and walk away.
Maybe these boxes will come in prewired from China.
If I was really doing a prefab job I would use snap in connectors. This should be scary to professionals since they are dumbing this down so much. The other question is what would you look at on the rough if the boxes were not there yet, just the stapling? Who inspects the prefabbed boxes? U/L? This brings up more questions than it answers.
I don't know, Greg. How do these devices really differ from them terminals in electronic lighting ballasts? I've seen a LOT of them burn out in the last few years, wether by vibration or elevated ambient temperature.
The ad also mentions that when you use a stranded wire, you don't need to twist it up first. How then, do you make sure that all of the strands are in the clamping part of the connector? I mean, for something that has such low insertion force, it makes me wonder exactly how much pressure is on the wire itself, if it isn't enough, I can see a poor connection occuring.
I can see that these things would be pretty good for wiring repairs, but I don't think I'd use them for any new work.
