Just kidding. Look at the package, As HH suggests. Also, use some common sense. Install the wirenut. Can you see bare copper? If, when you tug on the wirenut hard, does the tap come apart or does it stay together? Do you "feel" good about it after it is done?
I didn't buy the wirenuts. I was connecting up some smoke detectors that were not connected. In my basement, I had one that was powered, and two unpowered. Upon removing the one with power, I discovered a 14-3 wire that was not connected, so I connected this to the loop. The other smokes turned on. The wire nuts seem heavy duty, with flanges.
The main smoke had one in and one out, one for the interconnect, and another one, and then the stranded wires for the smoke's connector. That makes 4 conductors and one stranded wire for the smoke's connector for 2 wire nuts (hot and neutral). The wire nut felt fine after it was screwed together. Just wondering if there's any chance of overheating.
