The Dangers of Up Sizing an Electrical Circuit Breaker

The purpose of a fuse or circuit breaker is to protect the electrical circuit wiring and components against overheating and electrical short or fault. Circuit protection with a fuse or breaker is  accomplished by specific sizing for the specific circuit and wiring type that is installed. Altering the original fuse type or size or the circuit breaker size with a larger size will endanger the electrical circuit wiring and components.
