What is the reasoning behind certain electrical breakers?
It’s probably a wiring capacity issue, as true states. You really don’t want to swap in a bigger breaker unless you want to significantly increase the chances of the units burning down. More seriously, swapping breakers probably violates your building code and likely will allow your insurance company to ignore fire claims. If you want to upgrade the breaker, you probably want to talk to an electrician about rewiring your circuit. That will cost a lot of money and be fairly disruptive. Constantly tripping a breaker is bad. Every time a breaker trips, the connecting wire heats up and cooks the insulation. Eventually heat-damaged insulation, romex, asbestos or paper will degrade enough to create a serious fire hazard. If it’s a wall plug circuit that doing this, seriously consider installing GFI plugs. Ground-fault plugs essentially put a breaker in every socket and protect your house wiring from damage. If you do it yourself, and it’s very simple, and changing your plugs will only cost $
