Are WAGO lever connectors approved for use in the US with #12 and #10 solid aluminum wire with the WAGO joint compound. The use would be for copper pigtailing of aluminum wiring.

  • You might want to revise this to ask about specific connectors by part number. The first and only one I looked up the data for was approved for copper only. It seems WAGO has a website that very specific, you should be able to find this information.

  • Thanks for looking this up. I finally found the information in the WAGO online catalog. Copper only for WAGO 222- and limited to 12AWG which would exclude its use for pigtailing 20-A circuits with 10 AWG aluminum. Nov 15, 2016 at 20:27

I finally found it in the WAGO online catalog WAGO 222-413 lever connector is listed for copper. There is no reference to aluminum. WAGO sells a joint compound in a syringe for injecting into these connectors and this made me hope that they were listed for solid aluminum, but it seems not so. I think it would work, but if it's not listed then one cannot use it for pigtailing aluminum wiring.
