Swapped from twist-on wire nuts to push-in connectors on commercial jobs

I used to swear by twist-on wire nuts for everything, spent 15 years using them on resi and light commercial. Then last fall I did a 200-unit apartment complex near Atlanta and after the 3rd time fixing a loose neutral I switched to Wago 221s. Honestly I feel like I'm saving 30% of my time on junction boxes now. Anyone else make the jump and see a real difference in troubleshooting later?

200 units is a lot of wire nuts to trust. Honestly, three loose neutrals on one job would have me questioning my whole approach too. I switched to push-ins six months ago for a 50-unit senior complex and haven't looked back once.

Push-ins on a 50-unit senior complex is a solid test run. If they held up there, 200 units is nothing. I've seen too many wire nuts fail on big jobs like that. The vibration alone from ceiling fans or HVAC can shake them loose over time. Push-ins just lock in cleaner and don't back off.
