Circuit Breaker Protection

The answer to the question of up-sizing a fuse or circuit breaker is ABSOLUTELY NOT!

Application: Installing an Electrical Circuit.
Skill Level: Advanced – a Licensed Electrical Contractor.
Estimated Time for the Electrician: Depends on age of the home, the condition of the electrical system and available access to electrical components to install an additional circuit.
Notice: Installing additional electrical wiring should be done with a permit and be inspected.

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.
