If you’re looking to install a NEMA EVSE Charging Station at home or for commercial use, understanding the proper installation method is key. This guide covers essential instructions, mounting options (wall-mount, pole-mount, pedestal, and back-to-back), safety steps, and required tools. Everything here is based on manufacturer documentation and real installation practices.
Before diving into the physical installation of your EV charger, review all included technical drawings (front, plan, and connection views). These will help you follow local codes and ensure proper placement of the EVSE unit.
Wear safety glasses when working with electrical tools or wiring.
Do not connect power while making or modifying wire connections.
Always follow lockout/tagout protocols when the unit is energized.
Use only the recommended tools to ensure proper fit and torque.
The NEMA EVSE charger is built to accommodate various mounting configurations:
Wall-Mounted
Ideal for garages or exterior home walls. Requires mounting screws and wire access through walls.
Pole-Mounted
Great for open parking lots or curbside installs. Offers vertical mounting using a conduit pole and secure bracket attachments.
Pedestal
A free-standing unit for parking areas. Common in commercial or multi-unit properties.
Back-to-Back Pedestal
Enables two EV chargers on a single pedestal – perfect for high-traffic EV stations.
Each configuration follows ADA standards for accessibility and mounting clearance.
Here are the main torque settings and fasteners:
| Screw Size | Torque | Tolerance |
