Peter from Union, NJ has been a Green Sun Energy Services client since October of 2023. The charger went in that January: a hardwired ChargePoint Level 2 unit rated 11.5 kW, mounted outdoors beside the meter on a dedicated 60-amp circuit. The load calculation put the minimum service at 128 amps against the 200-amp supply the house already had, so the circuit went in without the panel being touched. Three months passed between the contract and the installation, most of it the township permit – the part of an EV charger job that takes longest and shows least, and the part that separates a professional installation from an extension lead.

EV charger questions from Union homeowners
Does Union 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.
Is a lower charging rate enough for most households?
Frequently. A 32-amp setting is estimated at around twenty-five miles of range an hour, so an overnight window covers far more driving than most households do in a day. The charging rate worth installing is the one that refills a normal day comfortably, not the largest one the equipment can be set to.
