Our setup is in an unfinished driveway, 240 and 120 Lines (30 amp for EVSE, 20 amp for upgraded-portable EVSE, 120v for vacuum cleaner etc) buried in trench. Concrete cover in ground is junction box. All mounted on 4x4" steel post set in concrete. Mostly we use the main unit, but with two Leafs, we occasionally need to charge both at the same time.
