A manual reset CB will open during an overload or short circuit. One can then investigate the cause and adjust the load or repair the short before resetting the cb. An automotive auto resetting cb on the other hand will alternataly open and close on this overloaded or shorted circuit until someone intervenes, the load drops by itself, or the circuit burns open. I find the auto resetting automotive cb to be a bad idea in general, and a particulary bad idea in a residence.
Thanks for your feedback. I guess I'd like to hear/learn more about the potential dangers of using an auto-resetting breaker. Anyone else care to comment? If they were dangerous, would they use them in autos/RV???
I did find this very interesting video. Shows a cutaway of an auto-reset breaker in action.

In my case, the manual master reset breaker has tripped very rarely (and then went back to normal operation when reset manually)
I feel an auto reset breaker would be low risk in my scenario to date. But if there was a true short/etc that continually tripped the auto reset breaker what would be the likely outcome?
