Jozef from Metuchen, NJ has been a Green Sun Energy Services client since September of 2024. The charger is a ChargePoint Home Flex the household bought themselves; Green Sun did the electrical work and the installation, finished in October of 2024, on a NEMA 6-50 outlet with a J1772 connector. The load calculation put the minimum service panel at about 144 amps, which is the number that decides whether a charger circuit can be added at all – buying the unit is the easy half, and the panel is the half that says yes or no.

EV charger questions from Metuchen homeowners
Can an older Metuchen home on a 100-amp service charge an electric car?
Often, yes. A 100-amp house is not automatically disqualified from Level 2 charging. The options include commissioning the charger at a lower amperage, running a proper service-load calculation, using load management or a listed energy-management system, or upgrading the service where the numbers genuinely require it.
Can a ChargePoint Home Flex be set lower if the panel is full?
Yes -- that is the point of the adjustable output. A house that cannot carry 48-amp charging might run at 32 amps on a 40-amp circuit, or 24 amps on a 30-amp one, where the load calculation and the installation support it.
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.
