I usually use devices that have the pressure plate terminals with stranded wire. If I can't get those, then I crimp spade terminals onto the wires, and put them under the screw heads.
That's what I'll do with the traffic lights if the two-years-older
and dumber-than-me guy at the orange box gives me #10 instead of #14. Kinda hard to get the #10 under a terminal block screw w/o taking the screw out and losing it.
Gonna have to try the 'leave the insulation on' trick with the next signal.
