Tools and Materials Needed

• Tools:
  • Flathead and Phillips screwdrivers
  • Wire stripper/cutter
  • Voltage tester
• Materials:
  • Siemens plug-on neutral breaker
  • Personal protective equipment (gloves, safety glasses)
  • Electrical tape

Safety Precautions

Before you begin, prioritize safety:

1. Turn Off Main Power: Ensure the main power supply to the panel is turned off to prevent any electrical hazards.
2. Verify Power is Off: Use a voltage tester to confirm that there is no electrical current in the panel.
3. Wear Protective Gear: Always wear appropriate personal protective equipment such as gloves and safety glasses.

Step-by-Step Wiring Instructions

Step 1: Remove the Panel Cover

Using a screwdriver, carefully remove the screws holding the panel cover. Lift the cover away from the panel without damaging it.

Step 2: Identify the Neutral and Ground Bars

Locate the neutral bar, usually a silver bar with white wires, and the ground bar, often a green or bare copper wire.

Step 3: Prepare the Wires

Strip about 1/2 inch of insulation from the ends of the wires you will be connecting to the breaker. Properly preparing the wires ensures a secure and efficient connection.

Step 4: Install the Plug-On Neutral Breaker

• Align the Breaker: Position the Siemens plug-on neutral breaker with the slots in the load center.
• Insert the Breaker: Firmly press the breaker into place, ensuring it snaps securely onto the bus bar.

Step 5: Connect the Neutral Wire

Insert the stripped end of the neutral wire into the neutral terminal on the breaker and tighten the screw to secure the connection.

Step 6: Connect the Hot Wire

Insert the stripped end of the hot (black) wire into the terminal on the breaker and tighten the screw for a secure fit.

Step 7: Connect the Ground Wire (if applicable)

If a ground wire is required, connect it to the ground bar in the panel.

Step 8: Double-Check Connections

Ensure all connections are tight and secure. Check for any loose or exposed wires.

Step 9: Replace the Panel Cover

Carefully place the panel cover back over the load center and secure it with the screws you removed earlier.

Step 10: Restore Power

Turn the main breaker back on to restore power to the panel. Test the newly installed breaker to ensure it is functioning correctly.
