Can You Change A Breaker From 15 To 20

Can You Change a Breaker from 15 to 20 Amps? A Comprehensive Guide

Meta Description: Upgrading your breaker from 15 to 20 amps might seem simple, but it's crucial to understand the safety implications and electrical code requirements. This guide explains when it's safe, the process, and potential pitfalls.

Thinking about upgrading a 15-amp breaker to a 20-amp one? It's a common question, especially when dealing with increased power demands in your home. While it might seem like a straightforward fix, it's essential to approach this task with caution and a thorough understanding of electrical safety and local building codes. This article will guide you through the process, helping you determine if it's the right solution for your needs and how to do it safely.

Understanding Amps and Breakers

Before diving into the specifics, let's clarify what amps and breakers do. Amperes (amps) measure the amount of electrical current flowing through a circuit. A breaker acts as a safety device, cutting off the power if the current exceeds its rating, preventing overheating and potential fires. A 15-amp breaker is designed to protect circuits with a maximum load of 15 amps, while a 20-amp breaker protects circuits with a maximum load of 20 amps.

When You Might Consider Upgrading

You might consider upgrading a 15-amp breaker to a 20-amp breaker if you're experiencing frequent tripping. This often indicates that your circuit is overloaded, meaning it's drawing more current than it's designed to handle. This could be due to:

• Adding new high-power appliances: A new refrigerator, air conditioner, or microwave might draw enough current to overload a 15-amp circuit.
• Multiple appliances on one circuit: Running several energy-intensive appliances simultaneously on the same circuit can easily exceed the 15-amp limit.
• Outdated wiring: Older homes may have wiring that's not up to current standards, making it more prone to overheating.

Can You Simply Swap the Breaker? The Crucial Considerations

While it might seem easy to simply replace a 15-amp breaker with a 20-amp one, this isn't always safe or code-compliant. The crucial factor is the wiring gauge. A 15-amp breaker is typically paired with 14-gauge wire, while a 20-amp breaker requires at least 12-gauge wire. Using a 20-amp breaker with 14-gauge wire significantly increases the risk of overheating and fire, potentially leading to severe damage and injury.

Therefore, you should only change a breaker from 15 to 20 amps if:

• The existing wiring is 12-gauge or thicker. This is the most critical factor. Verify the wire gauge before proceeding.
• Your local electrical codes permit the upgrade. Check your local building codes to ensure compliance.
• You have the necessary electrical knowledge and experience. If you're not comfortable working with electricity, it's best to hire a qualified electrician.

The Process (Only if You're Qualified)

If all the above conditions are met, the process involves:

1. Turning off the power: This is absolutely crucial. Turn off the power at the main breaker panel before working on any circuit.
2. Removing the old breaker: Carefully remove the old 15-amp breaker from the panel.
3. Installing the new breaker: Install the new 20-amp breaker, ensuring it's correctly seated and making good contact.
4. Turning the power back on: Once the new breaker is installed, turn the power back on at the main panel and test the circuit.

Important Note: This is a simplified explanation. Improper installation can lead to serious consequences. Consult a qualified electrician if you're unsure about any part of the process.

Alternatives to Upgrading the Breaker

If you can't upgrade to a 20-amp breaker due to wiring limitations, consider these alternatives:

• Adding circuits: Installing additional circuits to distribute the load is often a safer and more effective solution.
• Replacing appliances: Consider upgrading to more energy-efficient appliances that draw less power.
• Hiring an electrician: A qualified electrician can assess your electrical system and recommend the best course of action.

Conclusion

Changing a breaker from 15 to 20 amps isn't a simple task. Safety and code compliance are paramount. If you're not confident in your electrical knowledge, always hire a qualified electrician. Improper installation can have dire consequences. Prioritize safety and ensure your electrical system is up to code.
