Wyatt from Lawrence Township, NJ has been a Green Sun Energy Services client since March of 2025. The charger went into the garage that April: a hardwired ChargePoint Level 2 unit rated 11.5 kW on a dedicated 60-amp circuit, within ten feet of the breaker box. The load calculation put the minimum service at 132 amps against the 150-amp supply the house already had, so the circuit went in without the panel being touched. That calculation is the check that decides whether an EV charger is a morning’s work or the start of a service upgrade, and it is far better done before anything is ordered than on installation day. A permit was filed with the township and a utility rebate application submitted as part of the job.

EV charger questions from Lawrence Township homeowners
Does a 200-amp service in Lawrence Township 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.
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 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.
