The breaker box, also known as an electrical panel or circuit breaker panel, is a critical component of your home’s electrical system. It plays a vital role in safeguarding your home from electrical hazards by controlling the distribution of electricity and providing protection against overloads and short circuits. Knowing how to check your breaker box is an essential skill for every homeowner to ensure the safety and functionality of your electrical system. In this article, we will provide a step-by-step guide on how to inspect your breaker box effectively.

  • Safety First

Before you begin, ensure your safety by taking the following precautions:

  1. Turn off all electronic devices and appliances in your home to avoid unexpected surges when working on the breaker box.
  2. Wear safety gear such as rubber-soled shoes and safety goggles.
  3. Ensure the area around the breaker box is dry and well-lit.
  4. Familiarize yourself with the location of the main power switch in case you need to shut off the entire electrical supply.
  • Identify the Breaker Box Location

Locate your breaker box, which is usually situated in a utility room, basement, garage, or an easily accessible area. It’s typically a gray or metal panel with a hinged door, and it may be labeled as “Electrical Panel” or “Circuit Breaker Panel.”

  • Open the Breaker Box Door

Gently open the door of the breaker box. Be cautious when handling the door, as it may be secured with screws or latches. Use a screwdriver if needed.

  • Examine the Labeling

Inside the breaker box, you will find a series of circuit breakers or fuses. Take note of the labels or directory provided, which indicate which circuit corresponds to which area of your home. Proper labeling makes it easier to identify and isolate specific circuits when needed.

  • Check for Tripped Breakers

A tripped breaker is one that has been automatically turned off due to overloading or a short circuit. To check for tripped breakers:

  1. Inspect the position of each breaker. A tripped breaker will be in the middle position, between the “ON” and “OFF” positions.
  2. Carefully push the tripped breaker to the “OFF” position and then back to the “ON” position. You should feel some resistance when resetting a tripped breaker.
  3. If a breaker immediately trips again after resetting it, it may indicate a more significant issue in the circuit. Consult an electrician for further assistance.
  • Test the GFCI (Ground Fault Circuit Interrupter) Outlets

In addition to circuit breakers, some homes may have GFCI outlets in areas like kitchens, bathrooms, and outdoor spaces. These outlets provide extra protection against electrical shock. To test GFCI outlets:

  1. Press the “TEST” button on each GFCI outlet. This should trip the outlet and cut off power to it.
  2. Press the “RESET” button to restore power. If the “RESET” button does not work or the outlet fails to reset, it may indicate a problem, and you should contact an electrician.
  • Replace Fuses if Necessary

If your home has a fuse box instead of circuit breakers, inspect the fuses for any blown or damaged ones. To replace a blown fuse, use the same type and amperage rating.

  • Close and Secure the Door

Once you have completed your inspection and any necessary actions, securely close the breaker box door. Make sure all screws or latches are properly fastened.


Knowing how to check your breaker box is a valuable skill that can help you identify and address electrical issues promptly, ensuring the safety and functionality of your home’s electrical system. Regular inspections can prevent potential hazards and keep your household running smoothly. If you encounter any issues or are unsure about the condition of your breaker box, it is advisable to seek the expertise of a licensed electrician for a thorough evaluation and any necessary repairs.
