We recommend always hiring a certified electrician to install the EV Charger. They'd be able to help figure out the specific installation requirements for your particular installation scenario like wire run/length from the electrical service to the charger, installing a NEMA plug (if needed) and more.
A professional installation is not required in many situations, but can be helpful unless you're comfortable working with residential electrical circuits at ~240V.
A certified electrician can also help with the permits needed in your area and they can certainly asks local regulatory questions that we are not aware of at Emporia.
We are building a network of installers across the 50 states, you can check the link below to see if we have Emporia partners in your zip code:
