I will be adding copper pigtails to a home with aluminum wiring. Are the (copper to aluminum) purple wire nuts a good way to go? There are other types too. Can or should I pigtail the wires for the beakers too?

What ever way you do it must be listed, so avoid the temptation of squirting anti-oxidant compound into a normal wirenut. I am under the understanding that purple wire nuts are about the only listed way to do this, but I might be wrong.

There are some other special crimp-on type connectors but I will probably go with the purple wire nuts.

Al,

The crimp-on connectors are the preferred way to go, but my understanding is that you have to be trained by the manufacturer to even purchase them.

Al,

Have you explored the liability issues that go along with this? Might be worth looking into.

There are 10 types of people. Those who know binary, and those who don't.

I think if you do a search on this site you'll find a lot of discussion about the AL wire nuts and the special crimpers. You might also find a link to some other web sights dedicated to this subject. I don't remember much good said about the blue Ideal nuts.

I think one issue with the crimper is the wires long enough to use the tool. Or do you have a bunch of short wires in a small box.
