1. Do I need a professional electrician to install the EV Charger?
Local codes may require a licensed electrician. If not, and you’re experienced with 240V systems, self-installation is possible.
2. Does Emporia Energy provide a list of qualified installers/electricians?
In most US areas, you can purchase an EV Charger with professional installation. Check availability at https://treehouse.pro/emporia.
3. What about ground fault protection?
The charger has built-in ground fault protection. Avoid installing on a GFCI breaker to prevent nuisance tripping. For more information on GFCI protections and installing the charger on GFCI breakers, refer to our detailed article. You can also find technical specifications on the protections provided on the device technical specifications PDF - found online here.
4. What wire diameter (AWG) should be used for power supply?
Use 6 AWG copper wire rated for 90°C to support the full 48-amp capacity. Consult an electrician for your specific setup. More information.
5. Is the EV Charger suitable for outdoor installations?
Yes, its NEMA Type 4 enclosure makes it suitable for both indoor and outdoor installations. More information.

9. Can I install the NEMA plug with the ground pin facing up?
Yes, but ensure there’s enough slack for the plug to turn without straining the cable.
10. Are higher amperage breakers acceptable?
