Scott from Fanwood, NJ has been a Green Sun Energy Services client since May of 2024. The charger is a ChargePoint Home Flex, hardwired rather than plugged in, on a 60-amp circuit, and it was finished in August of 2024. It delivers around 11.5 kW through a J1772 connector. The load calculation put the minimum service panel at about 145 amps, which on a house of this size is the number that settles whether a charger circuit can be added without touching the service first.

EV charger questions from Fanwood homeowners
Can an older Fanwood 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.
What is a ChargePoint Home Flex?
A Wi-Fi connected Level 2 residential charger with an adjustable output. Current Home Flex equipment can be configured for 16, 24, 32, 40, 48 or 50 amps depending on how it is installed, which is what makes it useful on a house whose electrical service cannot support the highest setting.
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.
