Daniel from Lebanon, NJ has been a Green Sun Energy Services client since October of 2023. A hardwired ChargePoint charger went in that December on a dedicated 60-amp circuit, with a J1772 connector and an estimated 36 miles of range added for every hour it charges. Hardwiring rather than plugging into a socket is what lets a unit run at its full continuous rating, and a circuit is sized at 125 percent of a continuous load, which is why a 60-amp breaker sits behind it. On a Hunterdon County commute that is a full battery every morning without anyone having to plan for it.

EV charger questions from Lebanon homeowners
Does a 200-amp service in Lebanon automatically have room for a 48-amp charger?
No. The rating on the service is not the same thing as the capacity left in it. The existing loads decide: electric heat, air conditioning, an electric range, a dryer, a water heater, a pool, a hot tub, solar equipment and anything else substantial all count against what is available. A load calculation answers the question; the number on the panel does not.
Can home charging be scheduled?
Yes. Both ChargePoint Home Flex and Tesla Wall Connector connect to their manufacturer's app and support scheduling and monitoring, which lets charging be moved into whatever off-peak window the utility rate offers. The same connection carries firmware updates and diagnostics.
Why does a 48-amp charger need a 60-amp breaker?
Because the electrical code treats EV charging as a continuous load, and overcurrent protection for a continuous load has to be sized at not less than 125 percent of it. Forty-eight amps multiplied by 1.25 is sixty, which is why 48 amps is the common maximum charging rate on a residential 60-amp circuit.
