Americo from Keyport, NJ has been a Green Sun Energy Services client since April of 2025. The charger went in that June: a hardwired ChargePoint Level 2 unit with a J1772 connector rated 11.5 kW, on a dedicated 60-amp circuit. The unit itself was supplied by the household rather than by us, which is a perfectly sensible way to do it – the equipment is often bought with the car, and what actually needs a contractor is the circuit, the permit and the inspection rather than the box on the wall. The load calculation put the minimum service at 99 amps against the 150-amp supply already in place, so the circuit went in without the panel being touched. A permit was filed and a utility rebate application submitted as part of the job.

EV charger questions from Keyport homeowners
Does Keyport inspect an EV charger installation?
Where the work requires an electrical permit, the municipal electrical inspector reviews it before the permit is closed. That inspection is the record that the circuit, the breaker, the conductors and the equipment connection were done to code, and it is worth having whether or not a rebate depends on it.
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 circuit does a Tesla Wall Connector need?
At its maximum 48-amp output it normally needs a 60-amp circuit, because the code requires overcurrent protection for a continuous load to be at least 125 percent of it. Where the electrical system cannot support that, the Wall Connector can be commissioned lower and put on a correspondingly smaller circuit.
