A 20-amp breaker is an essential component in electrical systems, protecting circuits from overloading and preventing potential fire hazards. If you are planning to buy a 20-amp circuit breaker, you might be wondering about its cost, factors affecting the price, and the different types available.
This content provides a detailed breakdown of the cost of a 20-amp breaker, including price variations based on brand, type, and features.
What Is a 20-Amp Breaker?
A 20-amp circuit breaker is designed to handle a maximum electrical load of 20 amperes before tripping to prevent overheating. It is commonly used for:
- Kitchen appliances (microwaves, coffee makers)
- Bathroom outlets (hairdryers, curling irons)
- Garage circuits
- Lighting and general-purpose outlets
These breakers ensure safe operation by automatically shutting off the power when excessive current flows through the circuit.
How Much Does a 20 Amp Breaker Cost?
The price of a 20-amp breaker varies based on several factors, including brand, type, and additional features. Below is a general pricing guide:
| Type of 20 Amp Breaker | Average Price Range (USD) |
|---|---|
| Standard Single-Pole Breaker | $5 – $20 |
| Double-Pole Breaker | $10 – $40 |
| GFCI (Ground Fault Circuit Interrupter) Breaker | $30 – $80 |
| AFCI (Arc Fault Circuit Interrupter) Breaker | $30 – $100 |
| Dual-Function Breaker (GFCI + AFCI) | $50 – $150 |
Factors That Affect the Price of a 20-Amp Breaker
1. Type of Breaker
The type of circuit breaker significantly impacts the price:
- Standard 20-amp breakers are the most affordable.
- Double-pole breakers are more expensive because they protect 240V circuits rather than the usual 120V.
- GFCI breakers are costlier as they provide additional protection against electric shocks.
- AFCI breakers prevent fires caused by arc faults, making them pricier than standard models.
- Dual-function breakers (GFCI + AFCI) combine both protections, leading to the highest cost.
2. Brand and Manufacturer
Some brands are known for their high-quality and durable breakers, leading to price differences. Popular brands include:
- Siemens $10 to $50
- Square D (Schneider Electric) $10 to $100
- Eaton $10 to $80
- GE (General Electric) $10 to $50
- Leviton $30 to $150
3. Retailer and Location
Where you buy your 20-amp breaker can also affect the price.
- Home improvement stores like Home Depot and Lowes usually offer competitive prices.
- Online retailers (Amazon, eBay) may have discounts but could include shipping fees.
- Local electrical supply stores may have slightly higher prices but provide expert recommendations.
4. Additional Features
Breakers with extra safety features like tamper resistance, surge protection, and smart technology can increase the price.

How to Choose the Right 20 Amp Breaker
When selecting a 20-amp breaker, consider the following:
- Check your circuit requirements Standard circuits need a single-pole, while large appliances require a double-pole breaker.
- Follow electrical code regulations Some areas mandate GFCI or AFCI protection.
- Buy from reputable brands High-quality breakers ensure durability and safety.
- Consider future needs If upgrading your home, a dual-function breaker might be a better investment.
Installation Cost of a 20 Amp Breaker
Apart from the cost of the breaker itself, you may need to hire an electrician for installation.
| Installation Type | Estimated Cost (USD) |
|---|---|
| DIY Installation | Free – $10 (tools) |
| Hiring an Electrician | $50 – $150 |
| Electrical Panel Upgrade | $500 – $2,000 |
If you have electrical experience, installing a 20-amp breaker is a simple DIY project. However, for safety reasons, hiring a licensed electrician is recommended, especially for GFCI and AFCI breakers.
Where to Buy a 20 Amp Breaker?
You can find 20-amp breakers at:
- Home improvement stores (Home Depot, Lowes)
- Online retailers (Amazon, Walmart, eBay)
- Local electrical supply shops
- Hardware stores
Always check for compatibility with your electrical panel brand and model before purchasing.
Frequently Asked Questions
1. Can I Replace a 15 Amp Breaker with a 20 Amp Breaker?
No, you should not upgrade a 15-amp breaker to 20 amps unless the wiring is designed for it. A 20-amp circuit requires 12-gauge wire, whereas a 15-amp circuit typically uses 14-gauge wire.
2. How Many Outlets Can a 20 Amp Breaker Handle?
A 20-amp circuit can handle up to 10 standard outlets, assuming each outlet draws 1.5 amps on average. However, if using high-power appliances, fewer outlets should be connected.
3. What Size Wire Do I Need for a 20 Amp Breaker?
A 12-gauge wire (12 AWG) is the minimum requirement for a 20-amp breaker. Using a smaller wire size can lead to overheating and fire hazards.
4. How Do I Know If My 20 Amp Breaker Is Bad?
Signs of a faulty breaker include:
- Frequent tripping
- Burn marks or a burning smell near the panel
- Breaker wont reset
- Buzzing noises
If you suspect a problem, replace the breaker immediately to avoid electrical hazards.
The cost of a 20-amp breaker varies depending on the type, brand, and additional safety features. On average:
- Standard single-pole breakers cost $5 – $20.
- Double-pole breakers range from $10 – $40.
