Using Wago's for old, solid aluminum wiring

[Nutmegger]

I see on their US-facing site that the 773 series push-in Wago connectors are "suitable" for connecting solid aluminum wire as long as their Alu-Plus paste is used (the link is below)
I don't see, however how a manufacturer saying on their site that something is "suitable" correlates to an NRTL listing.
in fact, the two UL "approvals" on that page say nothing of aluminum.
So, are they listed for Al or not, and what are the chance that they will pass an inspection?

I do know that some of the fixtures that come with Wago type connectors have AL wire in them, but other than that never came across that.

Do connectors have to be listed?

If you download their data sheets you will find:

Connectable conductor materials

Copper

Makes one think it's only allowed for Cu

There is a debate going on about whether WAGO is reliable with Copper. Now they are saying to use it with Aluminum...must be a misprint!

That's not what I see when I download the data sheet at the OP's link, it says the same as the web page, Copper and Aluminum.

That would certainly make aluminum connection corrections simpler.

That would certainly make aluminum connection corrections simpler.

One issue would be with 10 aluminum-- the info on the page states the connectors are only good for #12. Not sure if they make another size.

Are you sure the fixture wire is AL? Not tinned copper which is what most is? UL would not list a fixture with AL fixture wire. I know I would not be willing to install it.

I thought the same thing....#12 max

If they make 'em for #10 aluminum, some clown will use them on a 30 amp copper splice.

These are good for #10 copper, but not aluminum:

Yeah, lever connectors apparently can take stranded wire up to 10 AWG, but only copper. No aluminum at all.
Push-ins can do only up to 12 AWG
