everytime a circuit breaker trips, it's rated capacity actually decreases by 2 to 3 amps
Quite true, however Square D specifically states that they are suitable for fluorescent lighting loads; no mention is made about high current/high inductance loads like motors. Maybe they can handle it, but my GUESS is that it pertains to the high voltages present in fluorescent circuits. I would check with the mfg. and get their advice about using them for things like a/c. Of course, if the a/c isn't running, it doesn't make any difference.A lot of circuit breakers have the designation SWD on them which means they are rated for switching.
Can't argue with that. Every test I ever administered was open bookA guy who trained me always said "knowledge isn't just knowing the answers, it's also knowing where to find them if you don't".
