Lucid Home Connected Home Charging Station Total loss

[Ozzie118]

Really glad that the OP and his house / car are OK!! On the topic of the install manual for the Lucid home charger, is there a PDF version anywhere? I just bought one second hand from a forum member and now want to be 100% my electrician and I are familiar with every detail!!!!

It may be worth asking your electrician if they have any experience installing Lucid chargers. My electrician claimed to have installed hundreds of EV chargers but never a Lucid. A handed the installer the installation manual but he obviously didn’t care to read as right off the bat the terminal port was never plugged into the faceplate. Ironically enough, my wife was the 5th grade teacher of the apprentice tagging along for the job.

Compression lugs were not used but claimed that whatever alternative they used was acceptable.

This is why electrical work is one of the few things I am relatively comfortable “overpaying” for, as I’ve seen some really, really shoddy work. My installers, who knew what they were doing, and who worked directly with Lucid before the EVSE was even released, originally installed it on chair lugs and Lucid made them change it to compression lugs, as per the manual. My guess is your guys used chair lugs, or similar, and thus did not follow the spec. That’s on them, unfortunately.

Based on my experience with that, I’d guess the compression lugs are important.

I’m so glad to hear everyone is okay and it wasn’t worse.

Indeed. From what I could tell they did use chair lugs.

Yet other 80a chargers use chair lugs (mine non-Lucid charger supplied chair lugs with the charger and gave a McMaster-Carr item number for them). I assume yours was installed with the wrong size lug or more likely did not torque (either the lug to wire or wire to charger) them properly.

Other 80A EVSEs likely don’t specify that you *must* use compression lugs in the documentation / installation instructions; Lucid does. Therefore, the LCHCS must be installed with compression lugs.

It’s not that chair lugs can’t work for 80A circuits; they can. It’s that they can’t work in Lucid’s EVSE, evidently, because a) Lucid said so, and b) apparently they could burn your house down maybe?

I’m not an electrician, so someone knowledgeable is free to correct me. But that’s my understanding.

Can anyone post a picture of the correct compression lugs for the LCHCS?

First picture shows chair lugs (incorrect) and the second shows compression lugs (correct).

I sent my electrician home when he showed up without the correct torque screwdriver.


...and then I took the cover off to make sure the DIP switches were correctly set.

What is the part number for the compression lugs? Will these lugs "fit" 6 AWG wire for 56A operation? Is the torque requirement 26.9 lb-in.?
