Wago have increased the capacity of the 221 connectors, if you have a new box of Wago 221 Series they now connect conductor cross sections from 0.5 to 6 mm2 (20–10 AWG).
So they should adjust to suit the odd sized conductors and accommodate a bit of expansion and contraction, also they are plated, so are probably as good as it gets.
I went to find the customer who was sitting in his garden and he said he thought I had gone home, I replied that I had been writing a short essay in the comments box on his electrical certificates, then sat and had a conversation.
