purple aluminum

[Ponchik]

If I remember correctly the only proper way to pigtail copper with aluminum is by using compression connectors. Correct?

I vaguely remember the purple nuts are not designed, tested or UL listed.....

Can someone shed some light on this?

Thanks

This is Ideal's documentation. I use them when I need to.

Could have sworn I've seen Wago's for AL/CU, can't find them at the moment. iirc, they were also about $3 ea.

yep. who'd need more than three wires under a wirenut?

i got a few of these once.... put four of them in a single gang box, and then
try to fit a GFCI receptacle on top of them...... big fun!

I did a whole house update/remodel about a year ago, and left almost all the aluminum. But I added 4 dozen cans, only kitchen and two baths gutted.

So I was using existing aluminum switch legs, adding can lights. Alumiconns in the first cut-in can at each scheme was real tight.

The living room, though, had a two gang switch box and both switch legs got replaced, and we added a feed. There were already two aluminum feeds, so there was 5 wires - 2 al and 3 cu.

Only thing I could do was pigtail the two aluminum feeds to a single copper (3 times) then use copper-only Wagos to finish. A multi-gang box can for sure make you wish for more than 3 ports
