Robert from Belle Mead, NJ has been a Green Sun Energy Services client since October of 2023. The charger went into the garage in January of 2024: a hardwired ChargePoint Level 2 unit rated 11.5 kW on a dedicated 60-amp circuit, within ten feet of the breaker box. The load calculation put the minimum service at 121 amps against the 150-amp supply the house already had, so the circuit went in without the panel being touched. A follow-up service call the month after installation dealt with a further item on site, which is the ordinary shape of electrical work on an older house – the charger is straightforward, and what surrounds it sometimes is not. A permit was filed with the township and a utility rebate application submitted.

EV charger questions from Belle Mead homeowners
What electrical code applies to an EV charger installed in Belle Mead?
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 a home charger need Wi-Fi?
Basic charging does not depend on it, but the smart functions do: activation, scheduling, firmware updates, diagnostics, access control and any data a utility programme asks for. Some equipment sits in a reduced output mode until it is activated, so the network connection is worth setting up at installation rather than later.
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.
