I believe they do. When we built our house we already had a Tesla and knew we would eventually have more than one EV, so we ran a 50-amp and a 100-amp line in the garage with FEMA 14-50 plugs.
I believe the Lucid comes with a 240-volt charging cable, right? If so, we're going to skip the Lucid wall connector, as we don't really need the 19+ kW charge rate at home. I would find the ability use the car battery as an emergency power backup useful in some situations, but we already have a transfer switch hooked to a whole-house generator, and our electrician wasn't sure the Lucid setup could be ganged to the generator transfer switch.
Do you have any idea whether Lucid is staffed to handle technical questions from customers at the outset? Not only would my electrician need some wiring schematics should we want to use the wall connector with our generator, but I'm also planning to install a radar/laser detector, and I'm pretty sure our Lucid Dream will be the first one the installer has seen. When we had the system put in the Plaid, we found a lot had changed since our 2015 Tesla's radar installation. Tesla no longer had a switched 12-volt line, and the only way the installer could get the radar unit to power down automatically was to build and program an electronic module that could read the voltage drop that occurs on the line to the central screen when the main car systems power down. I'm pretty sure my installer will need some coaching from Lucid on his first install in a Lucid.
