- Connect the bare or green ground wire to the green grounding screw on the breaker.
Step 3: Secure the Breaker
After all wires are properly connected, ensure that the GFCI breaker is firmly seated in the panel. You may have to push a little to make sure it’s securely attached to the bus.
Step 4: Restore Power
Go back to your main electrical panel and turn the power back on. Once the breaker is energized, press the reset button on the GFCI breaker to ensure it’s operational.
Step 5: Test the GFCI Breaker
A crucial part of the installation is testing that your GFCI breaker is functioning correctly. Use the following steps:
- Locate the test button on the breaker.
- Press the test button; if functioning correctly, the GFCI should trip and cut off power to the circuit.
- If it tripped, press the reset button to restore power.
Common Mistakes to Avoid
While connecting a GFCI breaker might seem straightforward, there are several common mistakes that can occur:
Improper Wiring
Ensure that you’ve connected the wires to the correct terminals. Mixing up the line and load connections can lead to malfunctioning or unsafe installations.
