Mitch from Berkeley Heights, NJ has been a Green Sun Energy Services client since March of 2024. The charger went in that April: a hardwired ChargePoint Level 2 unit rated 11.5 kW on a dedicated 60-amp circuit, installed within ten feet of the breaker box. A permit was filed with the township and the work inspected, which is the part of an EV charger installation that separates a professional job from an extension lead – a 60-amp circuit is a substantial addition to a house’s electrical system, and it is inspected as one. A utility rebate application was submitted as part of the project.

EV charger questions from Berkeley Heights homeowners
What electrical code applies to an EV charger installed in Berkeley Heights?
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.
Why does the charger sit on a 60-amp breaker?
Because 48-amp charging is a continuous load, and the code requires the overcurrent protection for a continuous load to be sized at not less than 125 percent of it. Forty-eight amps multiplied by 1.25 is sixty. The breaker is not oversized; it is sized correctly for a load that runs for hours without pause.
ChargePoint Home Flex or Tesla Wall Connector -- which is better?
Both are good residential Level 2 chargers and the right answer comes from the cars, the electrical installation and any utility programme being applied for. Home Flex offers a slightly higher maximum output, a choice of J1772 or NACS connector, and plug-in or hardwired versions. Tesla offers close integration with Tesla vehicles, the Universal model for mixed households, and capable power management.
