How Much Is a New Circuit Breaker?

Are you in need of a new circuit breaker for your home or workplace? Perhaps you're experiencing frequent power outages or noticing other electrical issues that require attention. Whatever the case may be, it's essential to understand the cost associated with purchasing a new circuit breaker. In this article, we will explore the various factors that can influence the price of a circuit breaker, as well as provide you with some useful tips for finding the best deal. So, let's dive in and explore the world of circuit breakers and their price ranges.

Factors Influencing the Cost of Circuit Breakers

When it comes to determining the price of a new circuit breaker, several factors come into play. Understanding these factors will not only help you gauge the cost but also allow you to make an informed decision. Here are some key elements that can influence the cost of a circuit breaker:

The Type of Circuit Breaker

Circuit breakers come in various types, each designed for specific electrical systems and applications. The type of circuit breaker you need will depend on factors such as voltage requirements, current rating, and the specific electrical equipment you aim to protect. The most common types of circuit breakers include:

1. Miniature Circuit Breakers (MCBs): These are the most commonly used circuit breakers in residential and commercial buildings. MCBs typically have a lower current rating and are suitable for protecting light circuits and electrical equipment like lighting fixtures, small appliances, and outlets.

2. Molded Case Circuit Breakers (MCCBs): MCCBs are widely used for industrial applications and large electrical systems. They have a higher current rating and can handle heavier loads and power distribution requirements.

3. Ground Fault Circuit Interrupters (GFCIs): GFCIs are designed specifically to protect against electrical shock and are commonly used in areas where water is present, such as kitchens, bathrooms, and outdoor outlets.

4. Arc Fault Circuit Interrupters (AFCIs): AFCIs are designed to prevent electrical fires that can result from arcs in wiring. They are used in residential buildings and protect against fire hazards caused by faulty wiring.

The price of circuit breakers varies based on their type, with MCBs usually being the most affordable, followed by GFCIs, AFCIs, and MCCBs.

The Amperage Rating

The amperage rating, also known as the current rating, is another crucial factor that affects the price of a circuit breaker. The amperage rating indicates the maximum current that a circuit breaker can safely handle. Circuit breakers with higher amperage ratings tend to be more expensive due to their ability to handle larger electrical loads. Common amperage ratings for residential circuit breakers range from 15 to 200 amps. However, for industrial applications, amperage ratings can exceed 3,000 amps.

The Brand

The brand of a circuit breaker can also impact its price. Well-known and reputable brands often charge a premium for their products due to their established reputation for quality and reliability. However, it's important to note that not all high-priced brands are necessarily superior in terms of performance. It's recommended to do some research and read customer reviews before making a brand-based decision.

New versus Used Circuit Breakers

Purchasing a new circuit breaker is typically more costly compared to buying a used one. Used circuit breakers may be more budget-friendly but may also come with certain risks. It's vital to thoroughly inspect used circuit breakers for any visible signs of damage or wear and ensure they meet safety standards. Buying a used circuit breaker from a reputable source and having it tested by a professional can be a cost-effective option.

Where to Buy Circuit Breakers

Now that we've explored the factors influencing the cost of circuit breakers, let's discuss where you can purchase them. Here are some common places to buy circuit breakers:

1. Electrical Supply Stores

Electrical supply stores specialize in selling a wide range of electrical equipment, including circuit breakers. These stores usually have knowledgeable staff who can assist you in finding the right circuit breaker for your specific needs. Prices at these stores can vary, so it's always a good idea to compare prices between different suppliers before making a purchase.

2. Online Retailers

With the convenience of online shopping, many people prefer buying circuit breakers from online retailers. Online platforms like Amazon, eBay, and specialized electrical websites offer a vast selection of circuit breakers from various brands and types. Shopping online allows you to easily compare prices and read customer reviews, helping you make an informed decision. However, it's important to ensure that you are purchasing from a reliable and reputable seller.

3. Local Electrical Contractors

Local electrical contractors or electricians often have access to circuit breakers and other electrical supplies. They may be able to source the specific type and brand you need or offer guidance on the most suitable option for your requirements. Additionally, they might have relationships with suppliers that enable them to obtain competitive prices.

4. Salvage Yards

Salvage yards or scrap yards can sometimes have used circuit breakers available at a lower cost. These circuit breakers are typically obtained from dismantled structures or renovations. While purchasing from salvage yards can be an economical option, it's crucial to have them inspected by a professional to ensure they are safe and in working condition.

5. Wholesale Distributors

Wholesale distributors cater to businesses and professionals but may also sell to individuals. They offer products at discounted prices, making them a cost-effective option if you are purchasing circuit breakers in bulk or have a long-term project requiring multiple units.


In conclusion, the price of a new circuit breaker can vary based on several factors, including the type of breaker, the amperage rating, the brand, and whether it is new or used. To find the best deal, it's essential to consider your specific requirements, research various brands and suppliers, and compare prices. Remember, safety should always be a priority when dealing with electrical equipment, so ensure you purchase from reliable sources and consult with professionals if needed. By doing so, you can ensure the smooth functioning of your electrical systems while staying within your budget.
