As of the 1st of January 2019, the AS/NZS 3000:2018 Wiring Rules are now mandatory in Australia (late 2019 in New Zealand), including 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 for all power levels and to suit all electric vehicle charging applications.
The Delta range includes AC chargers at 7kW AC, and DC chargers for faster charging at 25kW, 50kW, 150kW.
When installing an AC electric vehicle charger, NHP recommends the device has its own dedicated circuit and upstream protection to guard against dangerous electrical faults. The minimum requirement specified in AS/NZS 3000:2018 Wiring Rules Appendix P for the Residual Current Device (RCD) is a Type A 30mA, provided the charger can ensure disconnection of the supply in the case of a DC fault current above 6mA.
If an electric vehicle charger cannot ensure disconnection, a Type B RCD is specified in AS/NZS 3000:2018 Wiring Rules Appendix P.
NHP’s Delta AC Mini Plus includes 6mA DC detection allowing it to safely operate with a Type A RCD, conveniently leaving no need for the higher priced Type B RCD to be installed and ensuring users are protected from any potential risks.
NHP considers the AC Mini Plus a fixed appliance and isolation is provided in the upstream protection. NHP also recommends the use of an isolator near the electric vehicle charger to assist with maintenance.
NHP is proud to be at the forefront of electric vehicle safety and is committed to ensuring your ongoing protection with the highest quality, compliant products in line with the updated standards.
