If the AC RCD detects a current imbalance exceeding safety thresholds, it trips and immediately shuts off the power to the Hypervolt.
External AC RCD protection safeguards EVs and EV charging systems by interrupting the power supply to the Hypervolt if any leakage currents are detected that might pose a risk of electric shock.
If you find that charging won’t start or has suddenly stopped, a good first step is to check that there’s power to the Hypervolt. To do this, check if the Hypervolt responds to the app and check if the LEDs are lighting up. If you suspect there’s no power going to the charger, the next step is to check if the RCD has tripped.
Locate Hypervolt RCD and check to see of it has tripped. To check if your RCD is working correctly, press the test button (if you have one) the switch should trip immediately. After testing, make sure the switch is set back to the ON position. If the switch fails to stay on, the RCD may have experienced a more serious fault.
Locating the RCD
Your Hypervolt may be connected directly to your main consumer unit or to a dedicated smaller consumer unit equipped with a type A, 40A double pole RCBO and a surge protector. Depending on your system’s layout you and your installer have opted for, a trip could occur at either one of these devices highlighted in green in the diagram below.
In some cases, your main property isolator, highlighted in red, may trip. If this happens, your entire property will experience a power cut. This can happen if ALM has not been configured properly on installation.
Frequent Nuisance Tripping
RCDs can become prone to frequent tripping for several reasons.
- Over time, the internal components may wear out, effecting its sensitivity, leading to more frequent nuisance tripping.
- If an RCD is not correctly rated for your circuit, or if unsuitable for the load, it may also lead to nuisance tripping.
The Hypervolt should be installed with a Type “A”, 40A double-pole RCBO
- External factors like lightning strikes or power surges can trigger the RCD to trip as a protective measure, but frequent surges can degrade the RCD’s sensitivity over time.
To improve protection, it's recommended to install SPD with your Hypervolt.
If you experience frequent nuisance tripping, it’s advisable to have the RCD inspected and possibly replaced.
