The new National Construction Code 2022 is now active, which includes new requirements for renewable energy equipment, electric vehicle charging and battery systems. This also includes new requirements for monitoring additional load.
Electrical distribution boards dedicated to electrical vehicle charging are now required in accordance with Table J9D4. The distribution boards are required to have the capacity to support the delivery and monitoring of the minimum power specified in J9D4 (2).
Time-stamped energy data collected from EV charging needs to be centralised in the same user interface as the energy meters from other individual loads on site.

Manage your EV charging efficiency with NHP load management solutions
EV chargers can easily add significant load to a building’s electricity supply. Most buildings were only developed to power the building’s original designed purpose, plus some buffer. EV chargers can easily exceed that buffer, causing significant load on the building’s power supply, which can result in an outage.
NHP’s Load Management System is designed to counter overloading the building’s capacity by dynamically controlling the draw from EV chargers. This solution features CT clamps, which are connected to the building’s mains supply and provide the system with live
data on the building’s current power demands. The proprietary NHP algorithm then analyses the reading, determines if the building is under load and issues adjusted instructions to the EV chargers to scaleback or ramp up charging speeds.
The NHP Load Management System also monitors the number of EV chargers currently in use and based on the building’s available supply, will control the chargers accordingly. The NHP Load Management System works in batches of up to 24 independent chargers at one time.
The NHP Load Management System is a once-off purchase and does not come with ongoing subscriptions or ongoing running costs. This makes the product a great cost-effective solution to managing EV charging needs.
Warranty, service and maintenance
As electric vehicles move from niche to mainstream for commercial use, the reliability of the network is paramount. EV infrastructure must ensure close to 100 per cent uptime. This requires a reliable and national network of service technicians who understand chargers inside-out. NHP’s fleet of mobile technicians are located nationally and are ready for deployment to site. NHP offers bespoke service packages which can support the maintenance of your infrastructure, whether as part of a regular service plan or ad hoc maintenance. NHP stocks a wide variety of parts in-country, ready for dispatch.
NHP’s Delta EV chargers come with a two-year factory backed warranty. NHP can support your organisation with extended warranties for up to 10 years.
