A circuit breaker opens a circuit under specified conditions. It is a protective device with a rating, not a switch with a convenient handle.
The dangerous idea is that a breaker which keeps tripping is the problem. It is the part that is working.
The rating is the whole point. A breaker is chosen to protect a particular circuit under a particular application, and that rating is what decides when it opens. Change the rating and you have not fixed anything -- you have raised the level at which protection arrives, on a circuit that was never designed for it.
Check yourself: The breaker keeps tripping, and a larger one would stop it. Fit it?
Answer: No. Never replace a breaker with a larger one just to stop tripping.
The breaker opened because the circuit it protects called for more current than that circuit permits. A larger device does not change what the circuit can carry; it just stops anything from opening until the current is higher still.
