Charging is limited to 24 amps (about 5.7 kW), which still adds roughly [15 to 20 miles of range per hour](https:\u002F\u002Fwww.psegliny.com\u002Fsaveenergyandmoney\u002Fgreenenergy\u002Fev\u002Fbasics\u002Fchargingbasics). The receptacle must be a grounded NEMA 14-30; older three-wire 10-30 outlets must be replaced first. NEC 625.40 requires an EV outlet to have its own branch circuit, so acceptance of a shared circuit is at the inspector's discretion; we confirm it with the inspecting authority before recommending one.","A lower charging setting: 24 to 32 amps [fully charges most cars overnight](https:\u002F\u002Fafdc.energy.gov\u002Ffuels\u002Felectricity-charging-home).","Dynamic load management for buildings: several chargers share one capacity limit and split it between cars.",{"heading":22,"paragraphs":23},"When a service upgrade is necessary",[24],"If the service is 60 or 100 amps and already near its limit, or you are adding a heat pump, induction range and EV together, [an upgrade is usually the better investment](\u002Fguides\u002Felectrical-panel-upgrade).
