To protect the circuit from overcurrent. — Circuit breakers protect against overcurrent, preventing damage to wires and equipment.

14 AWG — 14 AWG is suitable for 15-amp circuits according to standard electrical codes.

The circuit is overloaded. — Frequent tripping indicates the circuit is drawing more current than the breaker's rating.

12 AWG — 12 AWG is generally required for a 20-amp circuit to handle the increased current safely.

equal to or less than — The breaker must protect the wire, so its rating should never exceed the wire's ampacity.
