I ordered the Schneider from Home Depot. Used the Discover Card shopping link to get 10% off. Which puts the price at $720 after the 10%.
Schneider is a 7.2kw supply which is sufficient for the FFE's 6.6 kw charger.
Leviton unit looks nice but I don't see paying more than double for the same charging capability.
Schneider unit is made by Square D, and I've had no problems with their products.
You can easily make the Schneider a plug-in if you so desire. Buy a cord and a plug and diy or pay the electrician to install the plug on a cord for you.
Most people are finding that if they pay the electrician to install a suitable receptacle, the cost is much lower than if they pay to have the charger installed.
