Will a bigger breaker stop tripping?

Author: Prof. Mohamed Bosco  |  Last update: Saturday, July 19, 2025

When the breaker is tripping, it is almost never a good idea to replace it with a larger one. Here's why: It increases the risk of fire. If the breaker is tripping because it's overloaded (say, drawing 25 amps on a 20-amp breaker), increasing the size may cause the wire or the receptacle to overheat.

Can I get a bigger breaker if it keeps tripping?

No. Each piece of the rest of the circuit is rated for a maximum current. The breaker is designed to trip before any other part gets overloaded.

Is it safe to replace a 20 amp breaker with a 25 amp breaker?

Existing setup is perfectly fine and code compliant, you do not need to change the wire, period. You most likely would be fine leaving the 20A breaker as well. In the event that it trips due to startup current, you could change it to 25A.

Is it OK to oversize a breaker?

Oversizing a circuit breaker can be a safety concern. If there is a direct short in an appliance a breaker will kick off even if oversized, but if there is simply a crossed or burned wire it may not turn off.

How can I stop my breaker from tripping?

Electrical overloads are the main cause of breaker trips. Limit the number of devices plugged into the same circuit to avoid tripping the breaker. That might mean moving a few appliances or devices to another circuit or simply unplugging something.

What happens if you trip a breaker too much?

A circuit breaker prevents high amounts of electricity from overheating wires. If the wires get too hot, they can start an electrical fire. If your circuit breaker keeps tripping, don't wait to call one of our electricians.

How to fix an overloaded circuit?

If you're dealing with an overloaded electrical outlet or circuit, the first step is to reset the tripped circuit breaker. However, if the circuit breaker trips repeatedly, it's important to unplug whatever you can from the circuit and call a professional electrician to diagnose the problem.

Can I replace a breaker with a bigger breaker?

The answer: It's possible, but not advisable without an electrician evaluating the situation. You should never just upgrade from a 15-amp breaker to a 20-amp one just because the current one is tripping. Otherwise, you may burn your house down via electrical fire.

How do I know if I need a bigger breaker?

3 Signs You Need a Bigger Circuit Breaker Panel in Your Home
  • The Existing Box is Full. Your box is only set up to handle so many circuits at a time, and older electrical panels are often limited in how many circuits they can operate with. ...
  • A Burned Bus Bar. ...
  • Circuits are Internally Overloaded.

Can I use a 40-amp breaker on an AC unit?

It seems as though the 12-gauge conductors are improperly protected because they are connected to a large 40-amp breaker. But there's an exception in the code for air conditioning and heat pump equipment. And the 40-amp breaker on a 12-gauge wire is okay.

How to replace a breaker that keeps tripping?

How to Replace a Circuit Breaker
  1. Turn the Main Power Off. Locate the main circuit breaker and flip it to the OFF position. ...
  2. Remove the Breaker Panel Cover Plate. ...
  3. Remove the Old Circuit Breaker. ...
  4. Disconnect the Wires. ...
  5. Attach the Wires to the New Circuit Breaker. ...
  6. Insert the Breaker. ...
  7. Replace the Panel and Turn the Power On.

What happens if you put a 20 amp breaker in place of a 15 amp breaker?

Overloading the Wiring: A 15-amp breaker is typically connected to 14 AWG (American Wire Gauge) wire, which is not rated to handle the 20-amp current. Upgrading the breaker without upgrading the wiring can lead to overheating, melted insulation, and potential electrical fires.

How many sockets can I run off a 20 amp breaker?

In general, a 20A circuit should have no more than 10 outlets. The National Electrical Code (NEC) stipulates that the total load on a 20-amp circuit should not exceed 1250 watts. It includes all the outlets, lights, and appliances on the circuit.

How many times can a breaker trip before it needs to be replaced?

Every trip subjects the breaker to mechanical and thermal stress. MCBs are designed to handle a limited number of trips, typically ranging from 10,000 to 20,000 mechanical operations under normal conditions.

Why does my breaker keep tripping when I have nothing plugged in?

Circuit breakers can trip with nothing plugged in due to overloaded circuits, short circuits, ground faults, faulty breakers, loose connections, or wiring issues. This common issue can be puzzling and concerning, as it may indicate underlying electrical problems that need immediate attention.

How do you tell if a breaker is overloaded?

What Are the Warning Signs of an Overloaded Electrical Circuit? An obvious indication of an overloaded circuit is a breaker that keeps tripping and shutting off your power. Other signs of a circuit overload include: Lights that flicker or dim, especially when you switch on appliances or more lights.

Do I need a bigger breaker if it keeps tripping?

When the breaker is tripping, it is almost never a good idea to replace it with a larger one. Here's why: It increases the risk of fire. If the breaker is tripping because it's overloaded (say, drawing 25 amps on a 20-amp breaker), increasing the size may cause the wire or the receptacle to overheat.

What happens if you oversize a breaker?

Installing a circuit breaker with a larger amperage than recommended increases the risk of overheating, which can potentially ignite surrounding materials or wiring within the system.

Does a 20-amp breaker trip at exactly 20 amps?

The standard for most household circuits are rated either 15 amps or 20 amps. An important note to remember is that circuit breakers can only handle about 80% of their overall amperage. That means a 15-amp circuit breaker can handle around 12-amps and a 20-amp circuit breaker can handle about 16 amps.

What happens if I replace a 20 amp breaker with a 30 amp breaker?

very dangerous. 14 gauge wire is rated as 15 amps. even a 20 amp breaker is too big , a 30 amp breaker could cause the wires to over heat and burn down your house.

Should I use 15 or 20 amp breakers?

Unlike 15 amp breakers, 20 amp circuit breakers can carry more electrical current, and they use a thicker 12-gauge wire. That's why they are best for wiring a kitchen, laundry room, bathroom, garage, or dining room.

How much does it cost to change a 15 amp breaker to a 20 amp breaker?

Circuit breaker replacement costs $100 to $260 on average. Installing or adding a new circuit breaker switch costs $150 to $300, depending on the type, amps, and circuit length and complexity. Replacing a main breaker switch costs $200 to $600, while replacing a circuit breaker panel costs $850 to $4,000.

Does circuit overload fix itself?

A tripped breaker typically won't fix itself automatically. When a breaker trips, it interrupts the flow of electricity to prevent overload or short circuit conditions, protecting your home from electrical hazards.

Why won't my tripped breaker go back on?

Short circuit: When a circuit breaker won't reset or trips immediately after resetting, a short circuit is a likely cause. This is when a hot wire carrying a current touches a neutral wire. The circuit breaker detects this problem and trips as a safety mechanism.

How much does it cost to upgrade a circuit breaker?

Circuit breaker box upgrade: $500–$2,000. Replace a circuit breaker switch or fuse: $100–$250. Install a subpanel: $400–$1,750. Electric meter box installation or replacement: $200 to $800.
