Update: Switched from screw terminals to Wago connectors on panel wiring

I used to spend all day stripping wires and tightening screw terminals for every sensor and keypad connection. Six months ago I tried Wago 221 connectors for a 32-zone panel install in Denver. Cut my wiring time by about 40 percent and had zero loose connections on callbacks. The lever action makes testing circuits way faster too. Has anyone else made this switch and noticed a difference in your service calls?

I still use screw terminals on my main panels honestly. Had a Wago connector pop open on a rough-in and lost three zones of lighting. Never had a screw terminal fail on me like that.
