John from Keyport, NJ has been a Green Sun Energy Services client since November of 2024. A ChargePoint CPH50 went in that December – hardwired rather than plugged into an outlet, on a dedicated 60-amp circuit. That combination is what delivers 11.5 kW at the car, roughly 36 miles of range an hour: a 60-amp circuit carries 48 amps continuously, and hardwiring is what lets the unit take all of it. It also removes the plug and receptacle, which are the parts of a charging installation that heat and wear.

EV charger questions from Keyport homeowners
Does a home EV charger need an electrical permit in Keyport?
A new permanently installed EV charging circuit generally requires an electrical permit and inspection under New Jersey's Uniform Construction Code. Where a utility rebate is involved, the programme may also want evidence that the permit was closed out properly.
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.
What amperage settings does a ChargePoint Home Flex have?
Home Flex can be configured for 16, 24, 32, 40, 48 or 50 amps. It is commissioned at installation to match the circuit it is on and the capacity the house has spare, which is what lets the same charger suit a full panel and an empty one.
