Can I replace a 15 amp breaker with a 20 amp?

While it is technically possible to upgrade from a 15-amp breaker to a 20-amp one without an electrician evaluating the situation, it is not advisable. Simply upgrading the breaker because the current one keeps tripping could result in an electrical fire that could burn your house down. Therefore, it is always recommended to consult with an electrician before making any changes to your electrical system.
