Jane from Princeton, NJ has been a Green Sun Energy Services client since March of 2025. The charger went in that May: a hardwired ChargePoint Level 2 unit rated 11.5 kW, mounted outdoors next to the meter on a dedicated 60-amp circuit. The load calculation put the minimum service at 107 amps against the 200-amp supply the house already had, so the circuit went in without the panel being touched. Mounting beside the meter keeps the run short, and a short run is the cheapest part of any electrical job – the cost of an EV charger is mostly in the distance between the panel and wherever the car parks. A permit was filed with the township and a utility rebate application submitted.

EV charger questions from Princeton homeowners
Can a Tesla use a J1772 home charger?
Most Tesla vehicles can use J1772 Level 2 equipment with the appropriate adapter. Charging speed still depends on the vehicle and charger ratings.
Do utilities see when an electric car is charging?
Only where the homeowner enrols in a programme that asks for it. Smart-charging and charger incentive programmes commonly require the customer to authorise sharing charging data with the utility, which is used for administering the programme and for planning the grid. Outside such a programme, the charger reports to its manufacturer's app rather than to the utility.
Does a home EV charger need an electrical permit in Princeton?
A new permanently installed EV charging circuit generally requires an electrical permit and inspection under New Jersey's Uniform Construction Code. Where a utility rebate is involved, the programme may also want evidence that the permit was closed out properly.
