How to Upgrade Circuit Breaker

Have you ever experienced a power outage in your home? It can be frustrating to suddenly lose electricity and wonder when it will be restored. One of the culprits behind power outages is an overloaded circuit breaker. As the demand for electricity increases in our modern lives, it's essential to ensure that your circuit breaker can handle the load. In this article, we will explore the various ways you can upgrade your circuit breaker to prevent power outages and protect your electrical devices.

Understanding Circuit Breakers

Before we dive into the world of upgrading circuit breakers, let's take a moment to understand what they are and how they work. A circuit breaker is an electrical switch designed to protect an electrical circuit from damage caused by excess current. They play a crucial role in preventing electrical fires and safeguarding your home.

When the electrical current exceeds the circuit breaker's rated capacity, it automatically trips and interrupts the power flow. This action prevents the circuit from overheating, which can lead to fire hazards. However, not all circuit breakers are created equal. Older homes might have outdated circuit breakers that cannot handle the increased electrical demands of modern appliances and electronics.

Assessing Your Circuit Breaker's Capacity

Before considering an upgrade, it is vital to assess your circuit breaker's capacity. Determining its current capacity and comparing it to your electrical needs will give you an idea of whether an upgrade is necessary. Here's how you can assess your circuit breaker's capacity:

1. Calculate Your Electrical Load

Begin by calculating your electrical load, which is the amount of electricity your home consumes. To determine this, make a list of all the electrical devices, appliances, and lighting fixtures in your home. Each device typically has its electrical rating expressed in watts or amps. Add up all the ratings to calculate your total electrical load.

2. Read the Circuit Breaker Labels

Next, locate your circuit breaker panel or distribution board. Each circuit breaker should have its rating labeled on it. This rating indicates the maximum current that the breaker can handle without tripping. Take note of these ratings, as they will help you understand the capabilities of your existing circuit breakers.

3. Compare Load with Circuit Breaker Ratings

Now, compare your calculated electrical load with the ratings of your circuit breakers. If the total load exceeds the capacity of any individual circuit breaker, it's a sign that an upgrade is necessary. Overloading circuit breakers can lead to frequent tripping, power outages, and potential fire hazards. Upgrading your circuit breaker will ensure a smooth flow of electricity in your home and protect your electrical devices.

Upgrading Circuit Breakers

Once you've determined that an upgrade is needed, there are a few options to consider. Let's explore some of the common methods for upgrading circuit breakers:

1. Replace with Higher Ampere Breakers

If your circuit breaker panel has enough spare capacity, one straightforward method is to replace the existing breakers with higher-ampere ones. For example, if you currently have 15-amp breakers, replacing them with 20-amp breakers will increase the circuit's capacity. However, this option must be done cautiously. Before proceeding, consult an electrician to ensure your wiring can handle the increased electrical load.

2. Install Sub-panels

If your circuit breaker panel is already at full capacity, installing sub-panels can provide additional slots for new circuit breakers. Sub-panels act as extensions of the main panel and allow for the distribution of electrical circuits to different areas of your home. This option requires professional expertise, so it's advisable to hire a qualified electrician to install and connect the sub-panels properly.

3. Upgrade to a New Circuit Breaker Panel

In some cases, it may be necessary to upgrade your entire circuit breaker panel to accommodate your increased electrical needs. Older panels might have outdated technology, lower ampere ratings, or lack the necessary safety features. Upgrading to a new panel will ensure the reliability and safety of your electrical system. However, this is a complex task that should only be performed by a licensed electrician.

4. Consider a Smart Circuit Breaker System

For those who want to take their circuit breaker upgrade to the next level, smart circuit breaker systems are worth considering. These advanced systems provide real-time monitoring, control, and automation of your electrical circuits. With features such as remote access, energy usage tracking, and customized settings, smart circuit breakers offer enhanced convenience and energy efficiency.

5. Regular Maintenance

Regardless of the upgrade option you choose, it's important to conduct regular maintenance on your circuit breaker system. Inspecting for loose connections, cleaning the panel, and testing the functionality of the breakers will help identify any potential issues before they escalate. Routine maintenance will ensure the longevity and reliability of your upgraded circuit breaker system.


Upgrading your circuit breaker is essential to meet the increasing demands of modern electrical appliances and devices. Assessing your circuit breaker's capacity, understanding your electrical load, and comparing them can help determine if an upgrade is necessary. Whether it's replacing breakers, installing sub-panels, or upgrading to a new panel, there are various options available to meet your specific needs. Remember to consult a licensed electrician for professional guidance and assistance throughout the upgrading process. By ensuring the reliability and safety of your circuit breaker system, you can enjoy uninterrupted power and protect your valuable electrical devices.
