Switched from screw terminals to spring clamp connectors after 3 callbacks on the same panel in Cleveland.

Those screw terminals kept loosening up from vibration in a commercial freezer installation, but the spring clamps have held solid for 6 months now with zero issues, has anyone else made the swap for high-vibration spots?

Hard disagree on this one. Spring clamps have their place but swapping out screw terminals for them in a high-vibration spot sounds like a band-aid fix. Real issue there is probably the panel location or mounting, not the terminals themselves. Screw terminals with ring terminals and a dab of Loctite would have solved that freezer problem just as well. Spring clamps can be a pain to troubleshoot later, especially if you need to land multiple wires in the same slot. Is anyone really checking the torque specs on those screw terminals before blaming vibration?

Yeah you're probably right, I was just overthinking it.

Funny you mention Loctite, because I once used purple Loctite on a set of bathroom fans in a hotel and it somehow made the screws impossible to get out six months later. Still not sure if that was a reaction with the aluminum or just my bad luck with fasteners. Point is, sometimes the fix you think is solid just creates a new headache down the road.
