Why You Should NEVER Up-Size an Electrical Circuit Breaker or Fuse
The Dangers of Up Sizing Electrical Circuit Breaker, Electrical Question: Can I increase the amp rating on a breaker to fix a tripping breaker problem?
Tripping Circuit Breaker
Electrical Question: I am just wondering if I can up size the amp rating on a breaker in my fuse box to solve a overloaded circuit problem?
- I want to run a floor heater and a electric fireplace heater, but when I turn them both on the circuit breaker will trip OFF because it is only a 15 amp rated breaker.
- Can I just put a 20 amp or 30 amp breaker to fix the problem?
Thanks for your electrical question Darren.

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.
- NEVER UP SIZE A CIRCUIT BREAKER
- Up-sizing a circuit breaker or fuse will cause the circuit wiring to over heat.
- Overheated electrical wiring will create a serious fire hazard.
- Overheated electrical wiring would most likely cause your house to catch on fire!
Electrical Safety Tip:
- If your electrical system is overloaded,
- Or circuit breakers are tripping,
- Or fuses are blowing,
- Or you have something that requires more power,
- Then PLEASE, do not take chances, contact a local electrical contractor who will assist you with installing additional electrical circuits!
