A public EV charger is not installed by one person. It is put in by a team: the site host who owns or leases the land, a licensed electrical contractor who does the installation, the charger supplier, the network operator who runs the chargers afterwards, and the utility that supplies the power. If you are planning a site, you will deal with all five.
Key Takeaways
- A public charger is a team job: host, licensed contractor, supplier, operator and utility.
- The process runs capacity check, design and permits, groundworks and install, then commissioning.
- NEVI-funded sites add duties: 24/7 access, contactless payment, uptime above 97%.
- The operator’s role continues after installation — monitoring, payments and repairs.
The Five Roles Behind One Public Charger
| Role | Who it is | What they do |
|---|---|---|
| Site host | The business, landlord, council or fleet that controls the site | Commits the parking bays, funds or co-funds the project, signs the agreements |
| Electrical contractor | A licensed commercial electrical firm | Designs the supply, runs cables and switchgear, mounts and connects the chargers, arranges inspection |
| Charger supplier | The manufacturer or its distributor | Supplies the hardware, datasheets and certifications the design is built around |
| Charge point operator | The network company | Connects the chargers to its platform, handles payments, monitoring and driver support |
| Utility | The local electricity network company | Confirms capacity, provides or upgrades the connection the site draws from |
The electrical work itself follows the same rule as at home: it belongs to licensed electricians working to the electrical code, not to general builders. What changes at commercial scale is everything around that work — capacity studies, permits, groundworks and network onboarding. How site choice feeds into all of this is covered in our guide to where to install an EV charging station.
How a Commercial Installation Runs
- Feasibility and capacity. The contractor and utility check whether the site’s supply can carry the chargers, or whether an upgraded connection is needed first.
- Design and permits. Charger positions, cable routes, switchgear and signage are designed; permits and inspections are arranged under local rules.
- Groundworks and electrical install. Ducting, foundations and cables go in, then the chargers are mounted, connected and tested.
- Commissioning and onboarding. Each charger is configured, connected to the operator’s platform, set up for payment, and only then opened to drivers.
Costs split along the same lines, which is why the DOE-cited figures quote equipment and installation separately: about $3,500 plus $2,500 per connector for public Level 2, and $38,000–$90,000 plus $20,000–$60,000 for DC fast charging. The full picture is in our breakdown of commercial charging station installation costs.
The Rules the Team Builds To
EV charging is a continuous load under the National Electrical Code, so circuits are sized at 125% of the charger’s current, exactly as at home — just at larger scale. Federally funded corridor sites in the US carry extra duties under the NEVI standards in 23 CFR Part 680: stations open 24/7, contactless card payment with no membership required, average annual uptime above 97%, DC ports of at least 150 kW, CCS1 connectors on DC ports and J1772 on Level 2 ports. Those uptime and payment duties are also why the operator’s role does not end at installation: somebody has to keep the site inside those numbers every day. Whether the numbers work as a business is a separate question, covered in is an EV charging station business profitable?
Hardware the Team Installs
For shared parking and workplaces, the EV-AC03201T dual-connector AC station supplies two Type 2 connectors with up to 43 kW shared, OCPP 1.6J for network connection and RFID access. Where faster turnover matters, the EV-RHDC30K-L compact DC fast charger delivers 22 kW DC, also with OCPP 1.6J. Both are installed by the site’s licensed contractor and commissioned onto the operator’s platform like any other networked unit; our commercial charging page outlines the deployment options.
Frequently Asked Questions
Can a business’s own maintenance staff install its chargers?
The electrical installation still has to be done by licensed electricians under the applicable code and permit process. In-house staff typically handle the site decisions around the install, not the electrical work itself.
Who do I contact first if I want chargers at my site?
Start with either an electrical contractor with EV experience or a charge point operator. Both will pull in the other roles — supplier, utility and permitting — as the design takes shape.
Who maintains a public charger after installation?
Usually the charge point operator, under its agreement with the site host: monitoring, payment systems and repairs. Funded corridor sites must hold average uptime above 97%, which is why maintenance is contracted, not improvised.
