Sean from Garwood, NJ has been a Green Sun Energy Services client since January of 2025. The charger went in that March: a hardwired ChargePoint Level 2 unit rated 11.5 kW, mounted outdoors on a dedicated 60-amp circuit. The load calculation put the minimum service at 147 amps against the 200-amp supply the house already had, so the circuit went in without the panel being touched. Garwood is one of the smallest boroughs in Union County, and the older housing stock there is exactly where that calculation matters most – a house built long before anyone imagined charging a car overnight may or may not have the capacity, and the only way to know is to work it out. A permit was filed with the township and a utility rebate application submitted.

EV charger questions from Garwood homeowners
What should a Garwood homeowner look for in an EV charger installer?
One that treats the charger, the car, the electrical service, the permit and any utility programme as a single system rather than fitting a 60-amp breaker because the charger will take one. That means the household's actual daily driving, what the vehicle's onboard charger accepts, the connector, the service rating, a proper load calculation, the capacity left in the panel, Article 625 and the manufacturer's installation instructions, the correct breaker and conductor sizes, hardwired or plug-in, indoor or outdoor, the municipal permit and final inspection, commissioning and network setup, whatever incentives are open at the time, off-peak charging, how it interacts with solar or back-up power if the house has either, and the second car that may arrive later. The question worth asking is which charging system gives the house the speed it actually needs without upgrading the service unnecessarily.
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.
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.
