PAANO MAG INSTALL NG CIRCUIT BREAKER/BOLT-ON TYPE.

Introduction

This tutorial provides a comprehensive guide on how to install a bolt-on type circuit breaker. Understanding how to properly install circuit breakers is essential for ensuring electrical safety and functionality in your home or workplace. This step-by-step guide will cover everything from gathering the necessary tools to safely connecting the circuit breaker in your panel board.

Step 1: Gather Necessary Tools and Materials

Before starting the installation process, ensure you have the following tools and materials ready:

• Bolt-on circuit breaker (appropriate amperage)
• Screwdriver (flathead and Phillips)
• Wire stripper
• Electrical tape
• Insulated gloves
• Voltage tester
• Safety goggles

Tips

• Always ensure the circuit breaker you are installing matches the specifications required for your system.
• Double-check that the power is turned off before beginning work.

Step 2: Turn Off Power

For safety, turn off the main power supply to the circuit breaker panel:

1. Locate the main service panel.
2. Switch off the main circuit breaker.
3. Use a voltage tester to confirm that the power is off.

Common Pitfalls

• Forgetting to turn off the power can lead to electric shock. Always verify that the panel is de-energized.

Step 3: Remove the Panel Cover

With the power off, proceed to remove the panel cover:

1. Unscrew or unclip the cover using the screwdriver.
2. Carefully lift off the cover and set it aside.

Step 4: Identify the Installation Location

Determine where to install the new circuit breaker:

1. Locate an empty slot in the panel that corresponds with the size of the bolt-on breaker.
2. Ensure there is enough space and that it is compatible with existing wiring.

Step 5: Connect the Wires

Now it's time to connect the wires to the new circuit breaker:

1. Strip the insulation off the ends of the wires you will connect.
2. Identify the load wire (usually black) and the ground wire (bare or green).
3. Connect the load wire to the terminal of the breaker.
4. Connect the ground wire to the ground bus in the panel.

Important Note

• Ensure that connections are tight to prevent overheating.

Step 6: Install the Circuit Breaker

Once wired, install the circuit breaker into the panel:

1. Align the breaker with the slot.
2. Push it in firmly until it clicks into place.

Step 7: Replace the Panel Cover

After the breaker is securely installed:

1. Reattach the panel cover using the screws or clips you removed earlier.
2. Ensure that all screws are tightened properly to maintain a secure fit.

Step 8: Restore Power

With everything in place, it’s time to restore power:

1. Go back to the main service panel.
2. Turn on the main circuit breaker.
3. Test the new circuit breaker by turning on the connected devices.

Testing

• Use the voltage tester to verify that the new circuit breaker is functioning correctly.

Conclusion

Installing a bolt-on type circuit breaker is a straightforward process that enhances the safety and reliability of your electrical system. Always remember to prioritize safety by turning off power and using appropriate tools. After installation, regularly check the functionality of your circuit breaker to ensure it operates properly. If you are unsure at any step, consider consulting a professional electrician.
