Is a Higher Amp Circuit Breaker Better?

What Exactly Is a Circuit Breaker?

A circuit breaker is designed to protect your electrical systems from overloads by interrupting the flow of electricity through your wiring when problems arise, such as a short circuit.
When a circuit breaker opens, it does so because the amount of electric current flowing through the circuit has exceeded the rating of the circuit breaker. An electrical circuit can exceed its ampacity (the maximum current it can safely carry) if too many electric devices are connected to it, which can lead to a short circuit or electrical overload.
In order to determine how much current a circuit breaker will trip, you need to understand its amperage rating (amps).

A typical circuit breaker for use in a house has a current rating of 15A or 20A, which tells you the maximum amount of electrical load that can be supplied to a household circuit without shutting off. The circuit will trip (turn off) if the load being placed on that circuit exceeds the rating of the breaker, interrupting the supply of electric power to protect against damage to the insulation and equipment connected to that circuit from too much current.

What Does "Higher Amp Circuit Breaker" Mean?

If you are using a larger protection device to protect a circuit from electrical overloads(the larger device being capable of passively handling more current), then typically you would use a 15-amp device as a minimum size when installing devices such as lights and appliances that use less power(which is why we have these devices)to provide circuit protection for those devices currently using less power and only a 30-amp size(exception being primarily for large electric devices such as water heaters and HVAC)to provide the necessary circuit protection for those devices.

Should a significant amperage circuit breaker benefit your electrical system? Not necessarily; this is the main source of confusion.

Is a Higher Amp Circuit Breaker Better?

The most important question we need to answer is if an increased voltage circuit breaker (will be better) than a standard circuit breaker... and that answer is not guaranteed to be "yes".....

We are currently explaining it as follows:

1. Connect Properly Sized Circuit Breakers to Load Circuit Wires: The size of the circuit breaker must be in accordance with the load requirements, and there should not be an excessive current flow through the circuit caused by an improperly sized circuit breaker. Therefore, the circuit breaker size must match the device it is connected to and will help prevent overheating of both the device and circuit breaker circuitry due to high heat from an excessive overload.

2. Extremely elevated placement is also dangerous; if you are using a breaker that has a normal breaker size for the wire size being connected, then it should be safe to use unless the breaker is exceeding the rated output. However, if a breaker is too large for the wire to be connected, then excessive amounts of amperage flow through the wire being connected to that breaker, resulting in both thermal and electrical failure and possibly starting a fire. Remember that the purpose of a circuit breaker is to help protect your whole electrical system from electrical overload; Circuit Breakers are not designed to regulate electrical current, rather they are made only to protect your complete electrical system.

3. The actual application of using a circuit breaker with a higher amperage rating as compared to the existing circuits and the devices rated for lesser amperage is not warranted if all components in the installation meet the necessary amperage requirements. For example, if you have installed a new Cooktop that requires more amperes than your existing fifteen-amp circuit provides, you would also have to provide for the additional current needed to operate the new appliance, thereby requiring you to add a new circuit breaker rated at twenty amps rather than continue with the old fifteen-amp.

4. Legal and Accessibility Compliance: The size of a breaker is determined by both local and building codes (LCB). When upgrading a breaker, upgrading an existing breaker must remain within the confines of these restrictions to maintain both legality and safety.

How to Check a Circuit Breaker?

Knowing how well your circuit breaker is functioning will assist you in determining if an upgrade is necessary. Refer to the following guide for assistance with your status evaluation.

Step 1 - Locating the Circuit Breaker: You can typically find your circuit breaker in the basement, garage, or utility area of your home.

Step 2 - Check the Breakers for a Tripped Breaker. Some breakers can be found in the Off or Neutral position on the panel (the switch moved to that position). To reset the breaker, move the switch back from Off to On.

Step 3 - Investigate Repeat Tripping: A breaker that regularly trips means there is either an issue in the powered equipment or the circuit is overloaded. Before changing the amperage size of your main breaker, determine if the feed line supplying the panel is also an issue; you may be creating a serious safety hazard.

Always prioritize safety. If you're unsure about the issue, consult a licensed electrician.

Other Factors to Consider When Choosing a Circuit Breaker

To choose the right circuit breaker, there are some aspects other than increased amperage that you should be aware of. Some things you should consider when selecting circuit breakers include:

You have several options for your breaker type: GFCI (ground-fault circuit interrupter), AFCI (arc-fault circuit interrupter), and standard breaker. This is important because each one has a different function depending on how you plan to use it.

Circuit breakers come in various configurations as well as varying levels of quality, based upon the craftsmanship and materials of the component. Selecting from well-known manufacturers that produce quality products ensures that you'll have confidence in the safety of your electrical systems.

Verify Compatibility: In addition to making sure the circuit breaker fits into the electrical panel, it should also have enough circuit breakers to meet your overall electrical requirements. Circuit breakers are made for specific applications, so check specifications before purchasing any type of circuit breaker.

When to Upgrade Your Circuit Breaker?

You might consider upgrading to a higher amp circuit breaker in certain scenarios:

- Adding high-power appliances, like an electric oven or HVAC system.

- Frequently tripping breakers, even with standard energy loads.

- Renovating your home, adding circuits, or upgrading your electrical panel.

You should contact an electrical professional if you notice any of the above problems. Have an electrician evaluate your electrical system for possible needs to upgrade it. Do not attempt to make any upgrades to your electrical systems unless you possess both the required education and experience in this area.

Final Thoughts

Is it true that high-amp breakers are superior? No. A higher amperage breaker will be able to supply more power than others, and if you have a breaker that is too large for the wires that it will be connected to, then this could lead to a dangerous situation. It is important to select the correct size of breaker according to the available power on a circuit, based on factors such as how much power can flow through the wiring, what the wire can handle (how much power it can carry), and any applicable laws.

When you are planning to upgrade your electrical system to accommodate additional appliances or increase your electricity needs, you must consult with a licensed electrician. The electrician will evaluate your existing electrical system, provide recommendations on how to improve or upgrade your system, and ensure that all new installations comply with National Electrical Code (NEC) safety standards. Your safety with respect to electrical systems is the top priority!
