What Size Breaker for ChargePoint Home Flex?

Choosing the correct breaker size for your ChargePoint Home Flex is crucial to avoid frequent tripping and ensure safe operation. 

The ChargePoint Home Flex can charge at various amperages, and the breaker size must match the maximum current:

• 30 Amps Setting: Requires a 40-amp circuit breaker.
• 32 Amps Setting: Requires a 40-amp circuit breaker.
• 40 Amps Setting: Requires a 50-amp circuit breaker.
• 48 Amps Setting: Requires a 60-amp circuit breaker.

According to the National Electrical Code (NEC), the circuit breaker should handle 125% of the continuous load to ensure safety. 

For instance, if your charger is set to draw 40 amps, the circuit breaker must be rated at 50 amps to accommodate the continuous load.

ChargePoint Home Flex Tripping Breaker – How to Fix in 5 Steps

Resolving the issue of your ChargePoint Home Flex tripping the breaker involves a systematic approach to identify and address the underlying causes. 

Here’s a detailed 5-step process:

1. Check the Breaker Size and Wiring:

• Verify that the circuit breaker size corresponds to the ChargePoint Home Flex’s maximum charging capacity. For example, if the charger is set to 48 amps, a 60-amp breaker is required.
• Inspect the wiring to ensure it is rated for the maximum load. For a 48-amp setting, 6 AWG (American Wire Gauge) wire is recommended.

2. Inspect the Charger Settings:

• Open the ChargePoint app to review and adjust the charger’s amperage settings. Ensure the settings align with the breaker’s capacity to prevent overloading.

• Check for any available firmware updates that may address stability or compatibility issues with your electrical system.

3. Examine External Factors:

• High ambient temperatures and other high-power appliances operating simultaneously can cause breaker trips. Ensure the charging station is not exposed to extreme conditions and reduce the load on the circuit by turning off other appliances.
• Use a multimeter to measure the voltage at the charger. The voltage should be within the standard range (typically 230-240V in the UK). Significant deviations can cause the breaker to trip.

4. Test the GFCI Function:

• Test the Ground Fault Circuit Interrupter (GFCI) function of the breaker. GFCI breakers trip when they detect an imbalance between the hot and neutral wires, indicating a potential ground fault.
• If the GFCI breaker is found to be faulty or overly sensitive, replacing it with a new one may resolve the tripping issue. Ensure the new GFCI breaker is rated for the appropriate amperage.

5. Reset and Monitor:

• Reset the breaker by turning it off and then back on. Start a new charging session and monitor the charger’s behavior for stability.
• Use the ChargePoint app to track charging sessions and identify any irregularities that may indicate ongoing issues.

How to Reset ChargePoint Home Flex?

Resetting the ChargePoint Home Flex can help clear minor faults and recalibrate the system. Follow these steps for a proper reset:

1. Power Off: Turn off the circuit breaker supplying power to the ChargePoint Home Flex.
2. Wait: Leave the breaker off for at least 10 seconds.
3. Power On: Turn the circuit breaker back on.
4. Check Status: Use the ChargePoint app to check the charger’s status and ensure it is functioning correctly. Look for a green light indicating that the charger is ready for use.

A reset can often resolve temporary issues caused by power surges or minor software glitches.

How Do I Adjust the Amperage on My ChargePoint Home Flex to Prevent Tripping?

Adjusting the amperage setting on your ChargePoint Home Flex can help prevent frequent tripping by aligning the charger’s power draw with your home’s electrical capacity. 

Here’s how to adjust the amperage:

1. Open ChargePoint App: Access the settings for your ChargePoint Home Flex through the ChargePoint app.
2. Select Device Settings: Navigate to the specific settings for your Home Flex charger.
3. Adjust Amperage: Select the desired amperage setting that matches the capacity of your circuit breaker. For example, if you have a 40-amp breaker, set the charger to 32 amps or lower.
4. Save Changes: Confirm and save the new settings.
5. Test Charging: Initiate a charging session to ensure the new settings prevent the breaker from tripping.

Adjusting the amperage helps manage the electrical load and ensures that the charger operates within safe limits.

Can ChargePoint Home Charger Trip GFCI Breaker After Being Hardwired?

Yes, the ChargePoint Home Flex can trip a GFCI breaker even after being hardwired due to several reasons:

• Ground Faults: Even minor ground faults can cause a GFCI breaker to trip. Inspect the installation for proper grounding and any potential faults.
• Overload Protection: Ensure the charger’s settings are appropriately configured to avoid overloading the GFCI breaker. The GFCI breaker should be capable of handling the charger’s maximum load.
• Compatibility Issues: Some GFCI breakers may be overly sensitive or not fully compatible with high-capacity chargers. Consulting with an electrician to choose a compatible GFCI breaker can help mitigate this issue.

Conclusion

Troubleshooting a ChargePoint Home Flex tripping breaker involves understanding the electrical requirements, ensuring proper installation, and adjusting settings through the ChargePoint app. 

Advanced EV owners can maintain a reliable and efficient home charging setup by following these detailed steps. Always consult with a certified electrician for any complex electrical work and refer to the official ChargePoint support resources for further assistance.
