Nope, the rack breaker and the panel breaker being the same amp rating (but different brands) will trip at slightly different times, or together as in the case of the short you found here. Usually breakers are coordinated so that the breaker in the rack will always trip first, and the one in the panel will delay slightly to avoid having to reset both. Another thing that affects breakers is how many times they have tripped then reset due to short circuits. A short will slightly (or seriously) burn breaker contacts every time, and eventually raise the contact resistance so high that even under light or normal loads, they will overheat and cause delayed tripping. Overloads have much less of a bad effect, but can wear the breaker out mechanically. Some EE's will specify a higher amperage feeder to the rack panel (in this case, say 50 or 60 amps) to allow for compressor inrush and to avoid a simultaneous trip of both breakers in cases like this. That also leaves room for upgrading the rack or adding on to it.

With wire nuts it's easier access. When wired to terminals tightly, you don't need to access it because it works. At least there are terminal strips. I would have called the manager and had him come in, then I would have turned off the mains and had him change the breaker with my supervision. That way I can say that I didn't mess with the wiring in the building.

I don't know why but hotels never seem to want to do PM. Then when it breaks and I say if this was looked at a year ago you could have saved thousands of dollars. Would you like to setup a PM contract? They say we will wait and see. I usually tell them I don't care if they do PM or not, not trying to hard sell them. Its funny, I make more money selling after hours service calls and loading up the parts canon to fix years of neglect.

@@rafaelgomez4304 It seems to be a lot more common in residential/commercial forced air units for sure. I did a lot of work with Trane commercial HVAC and the controls were 24v. From all the relays I saw in this rack, I can see why they did 24v, as it is easier to design controls and run remote thermostats/sensors when using 24v controls. (As you probably already know, any 120v control wiring has to be treated just like power wiring, but 24v controls can use Class 3 cabling and methods.)

Most branch circuit breakers are 10K AIC (Amps Interruption Capacity or Current) that's the short circuit rating. The overload is the number on the handle. So if both breakers have the same short circuit rating, then either or both may trip. If I'm installing a sub panel, I try to find a main breaker that has a higher short circuit rating, like 22K AIC, so as not to take out a whole panel, but even that's not a guarantee. Shorts are violent and there's a whole lot of current the transformer will let through and a lot of the time it's just a battle of the breakers of which will trip first.
