I too have been getting a lot of panels enclosures not square, (Square D not so square) or misaligned the panel board to enclosure so cover will not sit with breakers installed, one as much as 3/8 inch. Had one that for the screws to attach the cover, the one side of breakers had totally exposing breaker wire screws. Had to ream the cover holes enough to get the cover to both sit down on breakers properly and get all the screws in. Also seeing a lot of issues with the spot weld not actually making a weld, can see it was done but didn't securely fasten.
Issues not limited to Square D.
What happened to QC ?!!
Also Getting a lot of the N/G bus screws that will not holdup to the torque specs provided. The square/ Robertson bit will spin out before reaching torque and the slotted is not enough meat to catch either. It seems the screw hardening is not consistent. Kind of wish they would just use the ECX style as you get both features in one screw, but even with a given MFG that have used ECX, they have not been consistent in its use.
