What To Know
- A 20-amp circuit breaker can handle more electrical current than a 15-amp circuit breaker, allowing you to add more devices or appliances to the circuit.
- A 20-amp circuit breaker is less likely to trip than a 15-amp circuit breaker, even when the circuit is heavily loaded.
- Changing a circuit breaker from 15 to 20 amps is a relatively simple task that can be completed in a few minutes.
Electrical circuit breakers are essential safety devices that protect your home from electrical fires. They trip when the current flowing through them exceeds a safe level, preventing damage to appliances and wiring. In some cases, you may need to increase the amperage of a circuit breaker to accommodate additional electrical devices or appliances. This guide will provide you with all the information you need to know about changing a circuit breaker from 15 to 20 amps.
Safety Precautions
Before you begin any electrical work, it is important to take safety precautions to prevent injury or electrical shock.
- Turn off the power: Shut off the main circuit breaker or fuse to the circuit you will be working on.
- Test the circuit: Use a voltage tester to ensure that the circuit is not live.
- Wear protective gear: Wear gloves and safety glasses when working with electricity.
Tools and Materials
To change a circuit breaker from 15 to 20 amps, you will need the following tools and materials:
- New 20-amp circuit breaker: Choose a circuit breaker that is compatible with your electrical panel.
- Screwdriver: A Phillips head or flat head screwdriver, depending on the type of circuit breaker you have.
- Voltage tester: To verify that the circuit is not live.
- Electrical tape: To insulate any exposed wires.
Step-by-Step Instructions
1. Turn off the power: Shut off the main circuit breaker or fuse to the circuit you will be working on.
2. Test the circuit: Use a voltage tester to ensure that the circuit is not live.
3. Remove the cover: Locate the electrical panel and remove the cover.
4. Identify the 15-amp circuit breaker: Find the circuit breaker that is currently rated for 15 amps.
5. Disconnect the wires: Use a screwdriver to disconnect the wires from the 15-amp circuit breaker.
6. Remove the 15-amp circuit breaker: Pull the circuit breaker out of the electrical panel.
7. Install the 20-amp circuit breaker: Insert the new 20-amp circuit breaker into the electrical panel.
8. Connect the wires: Connect the wires to the 20-amp circuit breaker.
9. Tighten the screws: Use a screwdriver to tighten the screws that hold the wires in place.
10. Replace the cover: Put the cover back on the electrical panel.
11. Turn on the power: Restore power to the circuit by turning on the main circuit breaker or fuse.
When to Change a Circuit Breaker from 15 to 20 Amps
You may need to change a circuit breaker from 15 to 20 amps if:
- You are adding new electrical devices or appliances that require more power.
- You are experiencing frequent circuit breaker trips.
- The circuit breaker is old and needs to be replaced.
Signs of an Overloaded Circuit
If a circuit is overloaded, it can cause the circuit breaker to trip. Signs of an overloaded circuit include:
- Frequent circuit breaker trips
- Lights dimming or flickering
- Outlets or switches feeling warm to the touch
- Electrical cords that are hot or damaged
Benefits of Changing a Circuit Breaker from 15 to 20 Amps
There are several benefits to changing a circuit breaker from 15 to 20 amps:
- Increased power capacity: A 20-amp circuit breaker can handle more electrical current than a 15-amp circuit breaker, allowing you to add more devices or appliances to the circuit.
- Reduced risk of circuit breaker trips: A 20-amp circuit breaker is less likely to trip than a 15-amp circuit breaker, even when the circuit is heavily loaded.
- Improved safety: A 20-amp circuit breaker provides better protection against electrical fires by tripping more quickly when the current exceeds a safe level.
Final Note
Changing a circuit breaker from 15 to 20 amps is a relatively simple task that can be completed in a few minutes. However, it is important to follow the safety precautions and instructions outlined in this guide to ensure that the job is done correctly. By increasing the amperage of a circuit breaker, you can improve the safety and reliability of your electrical system.
What People Want to Know
Q: Can I change a circuit breaker from 15 to 20 amps myself?
A: Yes, you can change a circuit breaker from 15 to 20 amps yourself if you have the necessary tools and experience. However, it is important to follow the safety precautions and instructions outlined in this guide.
Q: What happens if I put a 20-amp circuit breaker on a 15-amp circuit?
A: Putting a 20-amp circuit breaker on a 15-amp circuit can be dangerous. The circuit breaker may not trip when the current exceeds 15 amps, which could lead to an electrical fire.
Q: How do I know if a circuit is overloaded?
A: Signs of an overloaded circuit include frequent circuit breaker trips, lights dimming or flickering, outlets or switches feeling warm to the touch, and electrical cords that are hot or damaged.
