Changing 15 Amp To 20 Amp Breaker

Upgrading Your Electrical Panel: Switching from a 15 Amp to a 20 Amp Breaker

Meta Description: Learn how to safely upgrade your electrical panel from a 15-amp breaker to a 20-amp breaker. This guide covers the necessary steps, safety precautions, and considerations for this common home improvement task.

Upgrading a circuit breaker from 15 amps to 20 amps might seem like a simple task, but it involves working with electricity, which can be dangerous if not handled correctly. This guide provides a comprehensive overview of the process, emphasizing safety and compliance with electrical codes. It's crucial to understand that if you're not comfortable working with electrical systems, you should always consult a qualified electrician. This information is for educational purposes only and should not be considered a substitute for professional advice.

Understanding Amps and Circuit Breakers

Before we dive into the process, let's quickly recap the basics. Amps (amperes) measure the rate of electrical flow. A higher amperage rating means the circuit can handle more power. A 15-amp breaker protects circuits designed to handle up to 15 amps, while a 20-amp breaker protects those handling up to 20 amps. Switching to a 20-amp breaker allows you to power more devices or higher-wattage appliances on that specific circuit.

Why Upgrade to a 20 Amp Breaker?

Several reasons might prompt you to consider this upgrade:

• Increased power needs: You might need more power for new appliances like a refrigerator, microwave, or space heater.
• Overloaded circuit: A frequently tripping 15-amp breaker indicates an overloaded circuit, necessitating an upgrade. However, remember that simply increasing the amperage doesn't solve the problem of too many devices on one circuit.
• Supporting higher wattage appliances: Modern appliances often draw more power than older models.

Assessing Your Circuit and Wiring

This is the most crucial step. Before even considering changing the breaker, you MUST verify that your wiring can handle the increased amperage. A 15-amp breaker often uses 14-gauge wire, while a 20-amp breaker typically requires 12-gauge wire. Using a 20-amp breaker with 14-gauge wire is extremely dangerous and can lead to overheating, fire, and electrical damage. Check the wire gauge carefully. If you are unsure, seek professional help immediately. Incorrect wiring is a major fire hazard.

The Steps Involved in Changing a Breaker (with Safety Precautions)

Disclaimer: These steps are for informational purposes only. Improper electrical work can lead to serious injury or death. If you are uncomfortable, call a qualified electrician.

1. Turn off the power: This is paramount. Turn off the main breaker to completely de-energize the panel. Then, use a non-contact voltage tester to double-check that the circuit is indeed off.
2. Remove the old breaker: Carefully remove the old 15-amp breaker. Note its position and any markings.
3. Check the wiring: As mentioned, inspect the wire gauge. If it's 14-gauge, you cannot safely install a 20-amp breaker. Replacing the wiring is a more extensive project requiring professional assistance.
4. Install the new breaker: Carefully insert the new 20-amp breaker into the panel, ensuring it is securely fastened.
5. Turn on the power: Slowly turn the main breaker back on.
6. Test the circuit: Check that the circuit functions correctly. Use a high-wattage appliance to ensure the circuit is adequately protected.

Important Considerations

• Local Electrical Codes: Always check your local electrical codes before undertaking any electrical work. These codes dictate acceptable practices and safety regulations.
• Professional Help: If you're not experienced with electrical work or unsure about any aspect of this process, don't hesitate to call a licensed electrician. Safety should always be the top priority.
• Circuit Load: Remember that even with a 20-amp breaker, overloading the circuit can still occur. Don't exceed the rated capacity of the circuit.

Upgrading your circuit breaker from 15 amps to 20 amps can be a beneficial home improvement, but safety must be paramount. Always prioritize safety and don't hesitate to seek professional help if needed. This simple upgrade, when done correctly, can significantly improve your home's electrical system efficiency and safety.
