| are wire nuts vibration resistant? |

| coppercone2:
I am watching a youtube video where someone replaces a crimp connector inside of a hand held circular saw with a electrical wire nut, such as you would find in an American outlet. Are they suitable for this purpose? |
| sokoloff:
I would say they're neither vibration resistant nor suitable for that repair. I don't like them on stranded wire at all and even less so to join stranded-to-stranded. |
| CatalinaWOW:
I find them frequently in commercial saws so they apparently don't have too much problem. Also found in ceiling fans and washing machines. I have never had a properly installed one fail, but they are not always easy to install properly. Requires proper size of a quality wirenut and careful initial alignment of the wires and the nut. Three or more hands about the size of an infant with Hulk like strength would be useful in some cases. |

If done correctly, it will be fine in that application. It does require some care and attention though. Both wires should be stripped to the same length and if using stranded should be lightly pretwisted by hand before applying the marrette. A small tape around both wires below the marrette after completion will prevent any tugging on the wires pulling the joint apart in the connector. Also using High quality and correctly sized connectors makes all the difference in the world when it comes to longevity and vibration tolerance. Source: Industrial Electrician: I use marrettes to make splices in equipment on a regular basis up to 600 VAC and in pretty harsh Canadian conditions, and the only failures I have seen have been due to either poor workmanship, defective connectors(Especially Wago style), or left too long in direct contact with Canadian winter (IE: enclosure left open) |
| ratio:
Some wire nuts, B-Caps for instance, have a live spring that expands around the wires as you screw the wire nut on. Makes 'em less reusable as the other type, but I've never had one rattle off that was correctly installed. Do be sure that you don't run them so far on that the wires poke out the top! |
