What an EV charger permit costs in New Castle County
How to apply in New Castle County
In New Castle County, in most of the US, installing a Level 2 (240 volt) home EV charger is handled as an electrical permit built around a load calculation and a single line diagram showing the new dedicated circuit. A Level 1 charger that simply plugs into an existing 120 volt outlet typically needs no permit unless new wiring is added.
What most EV charger permit applications include:
- For New Castle County, a Level 2 charger needs its own dedicated 240 volt circuit and requires an electrical permit with inspection, since each outlet installed for EV charging must be fed by an individual branch circuit with no other outlets on it (NEC 625.40).
- For New Castle County, the application includes an electrical load calculation showing the existing service panel has enough spare capacity for the added EVSE demand, worked out using the standard dwelling load calculation method (NEC 220.83).
- For New Castle County, the breaker or other overcurrent device feeding the charger must be sized for continuous duty, rated at not less than 125 percent of the equipment's maximum load (NEC 625.41).
- Plan submittal typically includes a single line diagram showing conductor size, breaker size, conduit, and panel rating, plus the charger's manufacturer specifications, since the EVSE itself must be a listed product (NEC 625.5).
- For charging equipment rated over 60 amps or over 150 volts to ground, the application has to show a disconnecting means installed in a readily accessible location and capable of being locked open (NEC 625.43).
- For New Castle County, the charger must be shown connected and fastened in place according to the manufacturer's installation instructions, whether it is hardwired or a plug in unit on a dedicated receptacle (NEC 625.44).

Inspections and closing out your permit
In New Castle County, a Level 2 EV charger installation gets a rough wiring inspection if any new conductors will be hidden inside walls, ceilings, or run underground, then a final inspection that checks the dedicated circuit, breaker sizing, any required GFCI protection, the disconnect, and the charger's listing before the permit closes.
- In New Castle County: if new EVSE conductors will be concealed in a wall or ceiling, or run underground, they must pass a rough wiring inspection before being covered, since that inspection confirms the dedicated branch circuit required for the charger (NEC 625.40).
