I have found wago levers to have a better grip than line, but the pushfits seem all the same
We have done some experiments to try get to the bottom of this. Have found that sometimes either will win a pull out test. However, if its installed correctly (properly inserted and lever in the closed position) LINE will comfortably exceed the pull out requirements of BS 60998.
Providing the cables are properly secured (by an appropriate enclosure or stapled) it is unlikely that an installation will require a pull our force in excess of BS60998.
