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
Can an older Garwood home on a 100-amp service charge an electric car?
Often, yes. A 100-amp house is not automatically disqualified from Level 2 charging. The options include commissioning the charger at a lower amperage, running a proper service-load calculation, using load management or a listed energy-management system, or upgrading the service where the numbers genuinely require 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.
Does a home charger need Wi-Fi?
Basic charging does not depend on it, but the smart functions do: activation, scheduling, firmware updates, diagnostics, access control and any data a utility programme asks for. Some equipment sits in a reduced output mode until it is activated, so the network connection is worth setting up at installation rather than later.
