Overview of Circuit Breakers

Circuit breakers play a crucial role in protecting electrical systems from overload and short circuits. They are designed to automatically disconnect the flow of electricity when they detect a fault, preventing damage to the electrical system and reducing the risk of electrical fires.

One of the most common types of circuit breakers found in residential settings is the 20 amp circuit breaker. These breakers are designed to handle the electrical load for a variety of household circuits, including lighting, receptacles, and small appliances. Understanding the factors that affect the cost of a 20 amp circuit breaker will help you make an informed decision when purchasing one for your home.

Factors Affecting the Cost of a 20 Amp Circuit Breaker

The price of a 20 amp circuit breaker can vary based on several factors. Here, we discuss the main factors that can influence the cost.

1. Brand

The brand of the circuit breaker can significantly impact its price. Top-tier brands like Square D, Siemens, and Eaton tend to be more expensive due to their reputation for high-quality products and reliable performance. However, there are also more affordable options available from lesser-known brands that can still offer good quality and protection.

2. Type of Circuit Breaker

The type of circuit breaker you require will also influence its cost. Standard circuit breakers, also known as single-pole breakers, are generally the least expensive option. However, more specialized breakers, such as Ground Fault Circuit Interrupter (GFCI) and Arc Fault Circuit Interrupter (AFCI) breakers, offer additional protection against ground faults and arc faults, respectively, but come at a higher price point. Dual-function breakers, which combine GFCI and AFCI protection, are also available but can be even more expensive.

3. New vs. Used

Another factor that can influence the price of a 20 amp circuit breaker is whether you purchase a new or used unit. While used breakers can be more affordable, they may not offer the same level of reliability as new ones, and their remaining service life could be shorter. In most cases, it's best to invest in a new circuit breaker to ensure optimal performance and safety.

Installation Costs

When budgeting for the cost of a 20 amp circuit breaker, it's essential to consider the cost of installation. While some homeowners may feel comfortable installing a circuit breaker themselves, it's generally recommended to hire a licensed electrician to perform this task to ensure the job is done safely and correctly.

The cost of hiring an electrician can vary depending on your location and the complexity of the installation. On average, you can expect to pay between $150 and $200 for a professional to install a 20 amp circuit breaker. Keep in mind that this cost may increase if additional wiring or panel upgrades are required.

Where to Buy a 20 Amp Circuit Breaker

To find the best prices on 20 amp circuit breakers, consider the following options:

  • Home improvement stores: Retailers such as Home Depot, Lowe's, and Menards often carry a wide selection of circuit breakers from various brands. These stores can offer competitive prices and the convenience of in-store pickup or delivery.
  • Online retailers: Websites like Amazon, eBay, and Walmart.com also offer a wide range of circuit breakers, often at discounted prices. However, it's essential to verify the authenticity and quality of the product when purchasing from online retailers.
  • Electrical supply stores: Local electrical supply stores typically carry a more extensive selection of circuit breakers, including harder-to-find models. While their prices may be slightly higher, they often have knowledgeable staff who can provide expert advice and assistance.

Tips for Saving Money on Circuit Breakers

To save money on your 20 amp circuit breaker purchase, consider the following tips:

  • Compare prices: Shop around at different retailers, both online and in-store, to find the best price for the circuit breaker you need.
  • Look for sales and discounts: Keep an eye out for sales or discounts at your local home improvement or electrical supply store.
  • Bulk purchase: If you need multiple circuit breakers, consider buying them in bulk, as this can sometimes result in a lower cost per unit.
  • Consider lesser-known brands: While it's important to prioritize quality and safety, you may be able to find a reliable circuit breaker from a lesser-known brand at a more affordable price.


The cost of a 20 amp circuit breaker can vary depending on factors such as brand, type, and whether it is new or used. In general, you can expect to pay between $10 and $50 for a 20 amp circuit breaker, with specialized breakers like GFCI and AFCI costing more. Additionally, installation costs typically range from $150 to $200 when performed by a licensed electrician.

To ensure you get the best deal possible, shop around and compare prices from different retailers and consider taking advantage of sales or discounts. Also, consider purchasing from lesser-known but reputable brands to potentially save on costs without sacrificing quality.

With this comprehensive guide, you should have a better understanding of the factors that affect the cost of a 20 amp circuit breaker and how to find the best price. By making an informed decision and prioritizing safety, you can protect your home's electrical system while staying within your budget.
