The new Wiring Rules (AS/NZS 3000:2018) coming into effect in Australia on 1st January 2019 and in New Zealand in late 2019 include additional informative standards for electric vehicle charging systems.

NHP offers a complete range of Delta electric vehicle chargers that comply with these standards to ensure maximum safety at all power levels. The range includes AC chargers at 7kW, and DC chargers at 25, 50 and 150kW for faster charging.

NHP recommends that, when installing an AC electric vehicle charger, it has its own dedicated circuit and upstream protection to guard against dangerous electrical faults. In the new Wiring Rules, the minimum requirement for a residual current device (RCD) is a Type A 30mA device, provided the charger can ensure disconnection of electrical supply in the case of a DC fault current above 6mA. Otherwise, a higher-priced Type B RCD is required.

NHP’s Delta AC Mini Plus charger includes 6mA DC detection, allowing it to safely operate with a Type A RCD, so users are protected from any potential risks. For good practice, NHP recommends the use of an isolator with the charger to assist with maintenance.
