DC Fast Charger Permit Requirements
What high-power charging adds to your permit set.
DC fast chargers (DCFC) draw far more power than Level 2 equipment, so their permit packages are more demanding. Here’s what to plan for in your EV charging station permit design.
What a DCFC permit package includes
Site plan
Charger, cabinet, and equipment-pad locations with electrical routing.
One-line diagram
Upstream gear, transformers, and protection clearly shown.
Load calcs & schedules
Load calculations and panel/switchboard schedules.
Sizing & protection
Cable, conduit, and overcurrent sizing with voltage-drop and short-circuit calculations.
Equipment specs
Specifications and UL/NRTL listing for the EVSE and protection equipment.
Code & clearances
NEC Article 625 plus the working-space and clearance rules of Article 110.
Service and utility considerations
DCFC sites often need a dedicated transformer or a service upgrade, and utility interconnection review is common. Confirming available capacity early — and documenting any upgrade — is the single biggest factor in avoiding delays.
How ELDAPRO handles DC fast charging
DCFC designs follow NEC Article 625 plus the working-space and clearance rules of Article 110, sized to the NEC edition your AHJ has adopted. Most DCFC and commercial projects require PE-stamped drawings.
ELDAPRO sizes the upstream gear, cabinets, and protection automatically and can deliver PE-stamped DCFC plan sets in all 50 states. See the full checklist in our EV charging station permit requirements guide.
