Requirements and Regulations
Charging station installations must comply with local, state, and national codes and regulations, and installation requires a licensed contractor. The contractor should know the relevant codes and standards and obtain approval from the local building, fire, environmental, and electrical inspecting and permitting authorities before installing EVSE.
You can learn about codes and standards typically used for U.S. PEV and infrastructure projects on the AFDC’s Codes and Standards Resources page.
To determine which codes and standards apply to your project, identify those that are in effect within your local jurisdiction. Some jurisdictions also have unique ordinances or regulations. EVSE is considered a continuous load by the National Electrical Code (NEC). An electrical contractor’s knowledge and application of the current NEC is required for a safe and code-compliant installation.
Consult PEV manufacturer guidance for information about the required EVSE and learn the specifications before purchasing equipment and electric services. In many areas, a site installation plan must be submitted to the permitting authority for approval before EVSE installation can proceed. A plan describes the use and locations of elements such as electrical system components, hazardous materials, EVSE, lighting, vehicle and pedestrian traffic flow, ventilation, signage and striping, safety and accessibility measures, and landscaping.
