Aluminum wire connections

[winnie]

Have not used these, only the wago 221s. But here is the link supporting the use of wago 222s and push ins with the anti oxide paste and Al wire. Only good up to 4mm² so won't work for 10AWG. (Described in post 12.)

Connecting aluminum and copper conductors is relatively rare in building installations. But if it's necessary, use WAGO Alu-Plus Contact Paste to connect aluminum and copper conductors with WAGO Connectors – quickly, easily and reliably.

I know WAGO has instructions for using connectors for AL wire but are they UL Listed for this in the US? I know when this came up in the past they were not.
The link Jon posted only mentions metric wire sizes and mentions AL wire in East Germany.

You still have a dissimilar metal issue doing that...

Of course you do but the AL CU wire nuts are listed for that.

Oops...agreed.

Good point. The link is for their US localized web page, but the (wago.com/us/...) but they don't explicitly state UL listed for use with Al conductors, and this might be a set of European instructions incorrectly pointed at US users.
