The UK market is filled with suppliers offering EV chargers, with new brands emerging all the time. A quick search reveals at least 14 different providers, many offering multiple models. Choosing the right charger starts with ensuring it has CE marking, guaranteeing it meets legal safety and quality standards.
Zaptec Pro chargers undergo rigorous testing and certification by the accredited TÜV SÜD in Germany. For installers, this certification confirms that the charger meets all standards required for CE marking, ensuring confidence in both safety and reliability.
Installing an EV charger comes with specific safety requirements. A key requirement is that every AC charging connection must include earth fault protection with a trip threshold not exceeding 30mA. This prevents electric shock in the event of a fault.
Earth fault protection is essential for safeguarding users from electric shocks caused by electrical faults. When a vehicle is charging, its bodywork is grounded. If an earth fault occurs, the protection system automatically disconnects the car from the power supply, preventing the bodywork from becoming live and dangerous.
Zaptec chargers, come with built-in earth fault protection. This eliminates the need for external protection in the fuse box, requiring only:
This setup simplifies installation, reducing both costs and equipment requirements.
Zaptec chargers utilise Type B protection, the most advanced system for preventing unnecessary charging interruptions due to harmless DC currents. Unlike Type A protection, which stops charging at DC currents above 6mA (even if they pose no real risk), Type B protection allows for charging in a wider range of conditions without compromising safety.
Zaptec chargers make safety effortless by automatically testing earth fault protection before every charge. This eliminates the need for manual testing in the charging station, unlike systems that rely on external fuse box testing. While regular testing of earth fault protection is recommended twice a year, Zaptec’s automation ensures continuous protection.
With built-in protection and automatic safety checks, Zaptec chargers offer a safe and reliable EV charging solution. Whether for home use or larger installations, Zaptec ensures optimal safety without added complexity or extra costs.
