I was looking at a breaker panel in high school today. Probably from around 2005 an upgrade to add ac. It hs a sticker inside that is seismically qualified. Any idea what that means? it is not NEC but NFPA which I think is fire code.

Maybe there's a positive locking setup to keep breakers seated when the roller coaster is, um...rolling...?

NFPA 70E is the National electric code (NEC)
I don’t feel like looking it up but my guess would be the breakers are bolt in as opposed to snap in to obtain a seismic rating.

Seismic qualified equipment is tested and designed to withstand earthquakes.
It involves cabinet strength, bus bracing, strength of insulators etc.
The mounting of the equipment also has to meet standards....Rod
