Review on Wago Push Wire Wall Nut Assortment: Efficient Solution for Industrial Electrical Needs by Jay Kenville

I have a Wago 221 Pocket Sized Lever Nut Assortment and a Wago 773 Push Wire Wall Nut. I couldn't use the 773 with stranded wire. The 773 uses insertion force to clamp the wire. I cannot insert a strand into hole 773 because there is resistance and the strands are bent. If you insert stranded wire into 773, you can't remove it and reuse 773 either. 773. 221 has no resistance when inserted. The stranded wire is easy to insert and you close the clamp to clamp the wire.
