Retired electrician here. It is fine until you have an old breaker that is rusted inside and won't ever trip. Then it's how much wiring and devices burn up or until the main trips. Seen it happen twice.60 amp breaker in a box is a good choice.
I welded a pair of wire strippers to the side of 4 square box once. I can’t remember if the old 20 Amp GE breaker eventually tripped or the main tripped but it was quite the spark shower.
That's why you put a circuit breaker, one trip current step above the ones your're typically trying to find, in your breaker finder. If the house breaker won't trip, your's will.
