Circuit breaker upgrade: a step-by-step guide to changing from 15 to 20
What To Know
- A safety device that automatically interrupts the flow of electricity when a circuit overloads or experiences a fault.
- Changing a circuit breaker from 15 to 20 can be a straightforward task with proper safety precautions and electrical knowledge.
- Why would I need to change a 15-amp circuit breaker to a 20-amp circuit breaker.
Electrical safety is paramount in any home. Circuit breakers play a crucial role in protecting your home from electrical hazards. When considering replacing a 15-amp circuit breaker with a 20-amp one, it’s essential to understand the implications and safety considerations involved.
Why Consider Changing a Circuit Breaker?
- Increased Power Demand: Modern appliances and electronics draw more power than older devices. A 15-amp circuit breaker may not be sufficient to handle the increased load, leading to frequent tripping.
- Remodeling or Renovations: Adding new electrical outlets or appliances may require a higher-amp circuit breaker to provide adequate power.
- Safety Concerns: If a 15-amp circuit breaker repeatedly trips, it may indicate an underlying electrical issue that needs to be addressed. Replacing it with a 20-amp circuit breaker could mask the problem and pose a safety hazard.
Understanding Electrical Basics
Before attempting to change a circuit breaker, it’s crucial to have a basic understanding of electrical concepts:
- Amperage (Amps): Measures the amount of electrical current flowing through a circuit.
- Voltage (Volts): Measures the electrical potential between two points.
- Circuit: A complete path for electricity to flow from a power source to a load.
- Circuit Breaker: A safety device that automatically interrupts the flow of electricity when a circuit overloads or experiences a fault.
Safety Precautions
- Turn off Power: Before working on any electrical components, always turn off the power at the main electrical panel.
- Use Proper Tools: Insulated screwdrivers and pliers are essential for working with electrical circuits.
- Wear Protective Gear: Wear safety glasses and gloves to protect yourself from electrical shocks or burns.
- Seek Professional Help: If you’re not comfortable working with electricity, it’s advisable to hire a qualified electrician.
Changing a Circuit Breaker from 15 to 20
Materials:
- 20-amp circuit breaker
- Insulated screwdriver
- Wire stripper (optional)
Steps:
1. Turn Off Power: Locate the main electrical panel and turn off the circuit breaker that powers the circuit you want to change.
2. Remove the Circuit Breaker: Use an insulated screwdriver to unscrew the screws holding the circuit breaker in place. Carefully pull it out of the panel.
3. Inspect the Circuit: Check the wires connected to the circuit breaker for any damage or loose connections. If you find any issues, address them before proceeding.
4. Connect the New Circuit Breaker: Strip about 1/4 inch of insulation from the ends of the wires. Connect the wires to the corresponding terminals on the new circuit breaker. Tighten the screws securely.
5. Insert the Circuit Breaker: Slide the new circuit breaker into the panel and tighten the screws.
6. Turn On Power: Return to the main electrical panel and turn on the circuit breaker.
Considerations
- Wire Size: Ensure that the wire size is rated for at least 20 amps.
- Circuit Protection: The circuit breaker should provide adequate protection for the circuit. A 20-amp circuit breaker is typically used for circuits with devices that draw up to 16 amps.
- Electrical Load: Calculate the total electrical load on the circuit before changing the circuit breaker. Exceeding the rated capacity can lead to overheating and potential fire hazards.
Alternatives to Changing a Circuit Breaker
- Installing a Subpanel: A subpanel can provide additional circuits and capacity to handle increased power demand.
- Upgrading Electrical Wiring: Replacing existing wiring with thicker gauge wires can increase the current-carrying capacity.
- Using a GFCI Outlet: A GFCI (ground fault circuit interrupter) outlet can protect against electrical shocks.
Wrapping Up
Changing a circuit breaker from 15 to 20 can be a straightforward task with proper safety precautions and electrical knowledge. However, it’s essential to ensure that the circuit is properly sized and protected to avoid potential hazards. If you have any doubts or concerns, consult a qualified electrician for assistance.
FAQ
Q: Why would I need to change a 15-amp circuit breaker to a 20-amp circuit breaker?
A: Increased power demand, remodeling or renovations, or safety concerns may warrant a higher-amp circuit breaker.
Q: Is it safe to change a circuit breaker myself?
A: Yes, if you have the necessary knowledge and follow proper safety precautions. However, it’s advisable to consult an electrician if you’re not comfortable working with electricity.
Q: What are the risks of using an undersized circuit breaker?
A: Overloading can lead to overheating, electrical fires, and damage to appliances.
Q: What are the benefits of using a GFCI outlet?
A: GFCI outlets provide additional protection against electrical shocks and are particularly useful in areas like bathrooms and kitchens.
Q: Can I change a circuit breaker without turning off the power?
A: It’s strongly recommended to always turn off the power before working on any electrical components to avoid potential shocks or injuries.
