Michael from Somerville, NJ has been a Green Sun Energy Services client since March of 2024. The charger went in on 12 April: a hardwired ChargePoint Level 2 unit rated 11.5 kW on a dedicated 60-amp circuit. The load calculation put the minimum service at 108 amps against the 200-amp supply the house already had, so the circuit went in without the panel being touched. Five weeks separated the contract from the installation, most of it the borough permit and the utility rebate paperwork – the parts of an EV charger job that take longest and show least.

EV charger questions from Somerville homeowners
Does Somerville 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 40-amp breaker?
Because 32-amp charging is a continuous load and the code requires overcurrent protection for a continuous load to be at least 125 percent of it. Thirty-two amps multiplied by 1.25 is forty. A 32-amp rate is estimated at roughly twenty-five miles of range an hour, which covers a normal day's driving comfortably overnight.
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.
