Is Your Circuit Breaker Trying to Tell You Something? The Surprising Reason It Keeps Tripping

As an electrical contractor, one of the most common issues I encounter in American homes is circuit breaker trips and fuse blows. These are important safety features in your electrical system that protect against overloading and short circuits, but they can also be a nuisance when they occur frequently. In this article, I’ll provide you with some tips on how to troubleshoot circuit breaker trips and fuse blows like a pro.

What is a Circuit Breaker?

A circuit breaker is a safety device that protects your home’s electrical system from overloading and short circuits. When too much current flows through a circuit, the breaker trips and interrupts the flow of electricity. This prevents overheating and potential fires.

Circuit breakers come in different sizes and amperages, depending on the electrical load they are designed to handle. They are typically located in a breaker panel or electrical service panel, which is usually located in the garage, basement, or utility room.

What is a Fuse?

A fuse is a safety device that operates in a similar way to a circuit breaker. It is designed to interrupt the flow of electricity when too much current flows through a circuit. However, unlike a circuit breaker, a fuse needs to be replaced once it blows.

Fuses come in different sizes and amperages, just like circuit breakers. They are typically found in older homes or in certain types of electrical equipment, such as air conditioning units or appliances.

Why Do Circuit Breakers Trip and Fuses Blow?

There are several reasons why circuit breakers trip and fuses blow. The most common causes include:

  1. Overloading: When too many devices are connected to a circuit, it can overload and cause the breaker to trip or the fuse to blow.
  2. Short circuits: When two wires come into contact with each other, it can create a short circuit that causes the breaker to trip or the fuse to blow.
  3. Ground faults: When a wire comes into contact with a grounded surface, it can cause a ground fault that trips the breaker or blows the fuse.
  4. Electrical surges: When the voltage in the electrical system spikes, it can cause the breaker to trip or the fuse to blow.

How to Troubleshoot Circuit Breaker Trips and Fuse Blows

When a circuit breaker trips or a fuse blows, it can be frustrating. However, with a little troubleshooting, you can often identify and resolve the issue yourself. Here are some steps you can take:

Step 1: Identify the Cause

The first step in troubleshooting a circuit breaker trip or fuse blow is to identify the cause. Check to see which breaker or fuse has tripped or blown, and then try to determine what caused it.

If the cause is an overload, you may need to reduce the number of devices connected to the circuit. If the cause is a short circuit or ground fault, you will need to locate and repair the damaged wire.

Step 2: Reset the Breaker or Replace the Fuse

Once you have identified the cause, you can reset the breaker or replace the fuse. To reset the breaker, simply flip it back to the “on” position. To replace a fuse, you will need to remove the blown fuse and replace it with a new one that has the same amperage rating.

Step 3: Test the Circuit

After resetting the breaker or replacing the fuse, you should test the circuit to make sure it is functioning properly. Turn on the devices connected to the circuit and monitor the breaker or fuse for any signs of tripping or blowing.

If the breaker trips or the fuse blows again, it may indicate a more serious issue that requires professional attention.

Step 4: Call a Licensed Electrician

If you are unable to identify or resolve the issue yourself, it is important to call a licensed electrician for assistance. Electrical

issues can be dangerous, and attempting to fix them without the proper knowledge and tools can result in injury or damage to your property.

A licensed electrician can help you identify the root cause of the problem and provide you with safe and effective solutions. They can also perform regular inspections and maintenance on your electrical system to prevent future issues from occurring.

Preventing Circuit Breaker Trips and Fuse Blows

While circuit breaker trips and fuse blows are common issues in American homes, there are steps you can take to prevent them from happening. Here are some tips:

  1. Avoid overloading circuits: Make sure you do not connect too many devices to a single circuit. Spread out your devices and use multiple circuits if necessary.
  2. Upgrade your electrical system: If your home has an older electrical system, it may be time to upgrade. A licensed electrician can assess your system and recommend upgrades that will improve safety and efficiency.
  3. Install surge protectors: Electrical surges can cause damage to your devices and overload your circuits. Installing surge protectors can prevent this from happening.
  4. Schedule regular inspections: Regular inspections by a licensed electrician can identify and resolve potential issues before they become serious problems.


Circuit breaker trips and fuse blows are common issues in American homes, but they can be easily resolved with some troubleshooting. By following the steps outlined in this article, you can identify and resolve the issue yourself in many cases. However, if you are unable to resolve the issue or if you have concerns about the safety of your electrical system, it is important to call a licensed electrician for assistance. Remember, safety should always be your top priority when dealing with electrical issues in your home.
