Kris from Far Hills, NJ has been a Green Sun Energy Services client since January of 2025. The charger went into the garage that March: a hardwired ChargePoint Level 2 unit with a NACS connector on a dedicated 60-amp circuit, with surge protection and a load management module fitted alongside it. The load calculation put the minimum service at 209 amps – the highest figure on the site – which is why the management module is there: rather than upgrading the service, it holds the charger inside what the existing panel can carry. NACS is the connector Tesla used and the rest of the industry has now adopted, so a charger specified this way suits the cars being sold today rather than the ones sold five years ago. A permit was filed with the township and a utility rebate application submitted.

EV charger questions from Far Hills homeowners
What electrical code applies to an EV charger installed in Far Hills?
New Jersey adopts the National Electrical Code through the Uniform Construction Code, and the edition in force statewide is what the municipal inspector enforces. EV charging is governed principally by Article 625, which covers the branch circuit, overcurrent protection, continuous loads, load management, the disconnecting means, ground-fault protection and cord management.
Does an EV charging receptacle need ground-fault protection?
The current code carries ground-fault requirements for receptacles used for EV charging. That requirement, and the nuisance tripping that can come with a high continuous load behind it, is one of the reasons hardwiring is often preferred for a permanent installation.
What is a Tesla Universal Wall Connector?
A version designed to charge both NACS and J1772 vehicles. It keeps Tesla's NACS connector and adds an integrated J1772 adapter, with a maximum output of about 48 amps. It is the more flexible Tesla option for a household running more than one brand of car.
