Default Aluminum to copper pigtails - options?

I have a customer that has aluminum wiring (70's home) and wants to do the copper pigtails. They sell the purple wire nuts for that i know, and some have used no-lox in regular wire nuts. I guess this is better than nothing, but not sure if its code approved. I know they make special crimps with a special crimper for them too. Heard you have to take a class to do it that way, (not sure). Anyone found the best way to do this? beside rewiring the whole house with copper. Is using the no-lox or purple wire nuts ok to use?
Thx,

Don't use "regular" wire nuts unless you want to be sued and arrested when the fire starts..

Not the only way to do it and CYA. I know other options. I talked about one above. There are more.

There are only four ways of doing it. The first three require you to return and inspect the joints every year.

1. The first Is the crimping method that require you to be certified and to lease there tool.

2. Alumicon, it's a rated splicing box. However you need a torque screw driver $385.00.

3. Go to lowes you can get the receptacle and switchs that are rated for aluminum wire.
Remember the older boxes are small. So splicing won't work all the time.

4. And last re-wire the house. Tell the owner to stop being cheap and prevent a potential hazard.

I had heard purple wire nuts weren't legal, only the approved crimps and crimper, and you can't get the crimper without taking the class unless you know someone, but I could be wrong. Also it seems like regular wire nuts with no-lox in them would be the same as the purple ones, other than the ends are more closed.
Anyway, sounds like a lot of extra wire nuts in a box, but beats a rewire.

Pretty much right, the screw inside is cut with square wire and that also helps to hold the wires together, but actually a tan twister is made the same.


The purple is to help get you off the hook. It costs more, but it has been tested and listed for the use, no matter what the guys who have an anti Ideal #65 website like to say about that.

The purple nuts do nothing but cover your ass. The construction and materials are the same.


For a price, the manufacturer is willing to share the liability with you.

I hate having to use them but, as a contractor, I must.

If it was my house, I wouldn't lose a minutes sleep over it pigtailing with regular nuts.

I mean, if normal wirenuts are dangerous, why aren't they all burning up? The actual number of wirenut failures that I've come across isn't any more than with copper wire.

It's who will certified and insure the customer.

If you can't have it insured then what's the point. Also can you do the work. Do you have coverage in your policy for this type of work.

All sounds right, and seems like the aluminum rated recepts & sw are the best way to go, cost and conveiniance wise, besides a rewire..
So I guess purple wire nuts are not legal?

It's not the wire nut. It's over or under torquing.

I would think if it is legal to use, then it would be covered under ins.
Still not sure about the purple wire nuts being legal just because they sell them at Home Depot. but.. I actually agree that if you tighten them correctly they will last. And, common sense, and logic doesn't always mix with bueaucrocy or on paper.

youre full of crap.

So what you are telling me is that if I do any of the first 3 things you mentioned in the list, I am required [with or without pay?] to come back in the peoples home and rip all the receptacles out and check the nuts?

I don't think he's saying its required, just a good idea. There are lots of things that are good to do for extra safety that don't get done. Almost every house I see, I could find many things wrong, unfortunetly thats life, you can't fix everything.

If I can't trust something to operate safely without yearly supervision, I'm not going to install it.

But I would also like to see that in writing, because I think you're mistaken.
