Tried using wagos on a 220v line and got a surprise

I swapped out a junction box on a 220v AC unit last month and used Wagos instead of wire nuts. The heat buildup was noticeable after 20 minutes, so I switched back to nuts and it stayed cool. Anyone else see this on high amp circuits?

Lot of people push Wagos too hard for high amp stuff.

Those things heat up fast on continuous 20 amp loads.

My 30 amp lighting circuit runs fine with Wagos for the last three years. They don't get hot or anything for me, so maybe it depends on the specific load.
