Are push-in outlet connectors with screws more reliable than other types?
Screw-down insert connectors are very reliable. They're really no different from a well-done loop under a screw. Just be sure to strip the wire to the correct length. There should be a gauge molded into the outlet back plate.
These aren't really &quot;push-in&quot; connectors since you still have to clamp them. The push-in connectors that are problematic use just a spring tab to engage the wire. They're to be avoided.
