King Innovation is peddling this new device in ECM. It is a set screw lug connector that allows up to 3 wires in an Al to Cu connection. Anyone tried them yet? How much are they each? It does look better than the purple twister.
From the looks of it (The picture, anyways), it just looks like a chunk of a neutral or ground bar from a breaker box, so I'm sure it will work fine.
As for how I know this, when I moved into my house, There was an anelectric stove circuit on a 50 amp circuit wired with #6 aluminum. At one time or another, someone decided to put in cabinets and move the stove about 30 years ago. My neighbor, the handyman, helped the previous owner move the stove outlet and he used a cut up buss bar to connect the extra length of wire. Guess he didn't have any split bolts in his coffee can of hardware.
30 years of everyday use at high current, no sign of overheating whatsoever. If my neighbor were alive, I dunno if he'd be proud or be angry he didn't patent his idea.
I've got my sample too. It is smaller than the Ideal Purple Twister, but it is still going to be tough shoving these into the small boxes used in mobile homes. Looks like a surface extension box will still be in order.
IMO, from looking at the device, I would much rather use it than a Twister.
Instructions state that the connector is for one time use, just like the twister.
Few things are harder to put up with than the annoyance of a good example.
