2. Planning and Design Considerations For EV Charging Stations
Effective planning is the backbone of a successful EV charger station project.
This stage determines layout, load capacity, utility serviceability, and long-term site performance.
EV Charging Site Evaluation
Before design, conduct a thorough evaluation of the job site:
Identify existing service entrances and utility infrastructure.
Confirm equipment mounting zones with adequate clearances.
Assess trenchability of ground surfaces and ADA-compliant access to charging units.
Observe traffic flow, turning radius, and pedestrian walkways.
Load Calculations and Service Sizing
Use NEC Article 220 to determine the total connected load.
Factor in simultaneous use patterns and diversity demand factors where appropriate.
For installations with multiple high-amperage chargers, expect to coordinate with the utility on transformer sizing or primary service upgrades.
Equipment Selection
EVSE should be chosen based on:
Mounting type (pedestal, wall, overhead)
Communication protocols (OCPP 1.6+, RFID, mobile app access)
Environmental rating (NEMA 3R or better)
UL or ETL listing compliance
Select smart-networked EVSE if remote monitoring, load balancing, or billing integration is required.
Electrical System Design
A single-line diagram should accompany every EVSE design package.
It must show:
Incoming service location and transformer (if applicable)
Panelboards, breakers, and conductor sizing
Conduit routes with voltage drop mitigation
Required grounding and bonding points
EVSE load ratings and dedicated circuits
Maintain NEC 110 clearances and ensure panel loading does not exceed 80% for continuous EVSE loads.
Utility and Permitting Coordination
Early utility engagement is essential.
Submit load letters and service upgrade requests before finalizing plans.
Simultaneously, begin the permitting process by preparing submittals, including:
Electrical plans
Site layout drawings
Load calculations
Equipment spec sheets
AHJ review timelines can vary from days to weeks depending on jurisdiction.
Be proactive.
Thorough planning saves time, reduces cost overruns, and ensures the system will pass final inspection and operate reliably.
💡 Pro Tip: Involve your utility provider early and maintain open communication throughout the project. Delays from service upgrades or transformer installations are one of the most common causes of missed deadlines in EV station builds.
3. Trenching, Conduit, and Layout Best Practices
Once planning is complete and permits are in hand, the next critical phase in EV charger station construction involves trenching and conduit installation. These foundational elements dictate not only code compliance but long-term system performance and maintainability.
Trenching Strategy
Start by marking all utility paths clearly with paint and flags in compliance with local dig-alert services. Use utility locating services before breaking ground. Trench depth should follow NEC 300.5 guidelines, which vary based on voltage and raceway type.
Standard trenching recommendations:
24 inches for direct burial of PVC conduit under concrete or driveways.
18 inches minimum under sidewalks or landscaped areas.
Consider soil type, water table levels, and existing infrastructure when choosing trenching equipment. Shoring may be required for deeper or unstable trenches.
Conduit Material and Sizing
Use Schedule 40 or 80 PVC for underground raceways, transitioning to rigid metal conduit (RMC) above ground where physical protection is needed. Properly size conduits to minimize voltage drop and allow for future circuit expansion.
Tips for conduit installation:
Use long-radius sweeps to ease wire pulls.
Avoid excessive bends—keep to a maximum of 360° between pull points.
Seal all conduits to prevent moisture ingress.
Color-code conduit or label per circuit to simplify future maintenance and expansion.
Pull Boxes and Expansion
Install appropriately rated pull boxes at long runs or directional changes exceeding 360°. Plan for future EVSE by stubbing additional conduits to unused parking stalls or equipment pads.
Include spare conduit runs in the design phase—it's significantly cheaper to install empty conduit during initial trenching than to retrofit later.
Concrete and Mounting Prep
Form and pour concrete pads for EVSE pedestals, bollards, and switchgear. Ensure pad elevation prevents water pooling and allows for proper drainage. Anchor bolts should be embedded according to the EVSE manufacturer’s mounting template.
Maintain NEC 625 spacing requirements and ensure clearances meet ADA guidelines.
💡 Pro Tip: Install pull strings or fish tape in every conduit run and leave detailed as-builts with photos. These small steps can save hours on commissioning day or during any future service work.
4. Electrical Wiring and Panel Installation
With infrastructure in place, the focus shifts to electrical wiring and panel installation—the technical heart of every EV charger station. Proper execution at this stage ensures code compliance, equipment longevity, and long-term operational efficiency.
Service Panel Configuration
Install a dedicated panelboard or subpanel specifically for the EVSE load, sized according to your calculated demand. Select panelboards rated for commercial duty, with busbars and breakers sized for continuous load applications (125% of nameplate current, per NEC 625).
Include:
Main lugs or main breakers as required
Surge protection devices (SPD) at panel level
Appropriately rated overcurrent protection for each EVSE branch circuit
Label all breakers clearly for inspection and future servicing.
Wiring and Circuit Protection
EVSE circuits must meet the following standards:
Conductors sized per NEC 310 and adjusted for voltage drop if necessary
Copper wiring preferred for improved conductivity and heat tolerance
THWN-2 or XHHW-2 insulation for underground or outdoor conduit pulls
Use GFCI breakers or GFCI protection integrated in EVSE, depending on product listing. For Level 2 and DCFC units, branch circuits must be dedicated and free from shared neutrals.
Grounding and Bonding
Ensure proper equipment grounding using a separate grounding conductor sized according to NEC 250. Bond all enclosures, raceways, and metallic components in accordance with manufacturer requirements and NEC standards. Install grounding electrodes as required by site-specific soil conditions or per utility coordination.
Voltage Drop Mitigation
Design feeder circuits with no more than a 3% voltage drop to EVSE locations. When long conduit runs are unavoidable, consider:
Upsizing conductors
Using 277/480V service where available to reduce amperage load
Installing local step-down transformers closer to EVSE units
Proper voltage ensures consistent charging speeds and reduces long-term wear on EVSE components.
Labeling and Documentation
Label all junction boxes, pull boxes, conduit stubs, and panelboards per NEC 110.16 and 408.4.
Include:
Equipment schedules
Wiring diagrams
Conduit/circuit IDs for each run
Accurate labeling not only streamlines inspections but is invaluable for future troubleshooting and system upgrades.
💡 Pro Tip: Don’t rely on standard residential wiring practices for EV installations. Treat every component—from panelboards to wire terminations—as if you're building a critical commercial system. The durability of the installation directly affects uptime and ROI.
