David from Carteret, NJ has been a Green Sun Energy Services client since November of 2023. The charger went in that December: a hardwired ChargePoint Level 2 unit rated 11.5 kW, mounted outdoors on a dedicated 60-amp circuit run from the panel. The service was measured before anything was ordered and had the headroom to carry it, which is the step that decides whether a charger install is straightforward or turns into a panel upgrade. Sixty amps is a substantial addition to a house, and finding out that the service cannot take it after the equipment has arrived is an expensive way to learn.

EV charger questions from Carteret homeowners
What electrical code applies to an EV charger installed in Carteret?
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.
Can a ChargePoint charger charge a Tesla?
Yes. ChargePoint offers Home Flex with either a J1772 or a NACS connector. The NACS version connects directly to compatible Tesla vehicles, and the J1772 version charges a Tesla through the adapter Tesla supplies.
