The real test on the control system will be when we start putting high current through these WAGO connectors. I have seen more failures with these things than not under high current. The little metal tab which contacts the wire (typically about 1/4 the wire size) has a tendancy to heat up and cool down losing its spring ability and thus losing contact. Expecially with constant movement and shock.

At our new Menards in Holland I have personally replaced about 40 of their wirenut versions which use the exact same concept, 6 of which had such a catastrophic failure that the fire department was called.
