To give seven examples, in Lake Charles, Mobile, Pearl, Shreveport, Alexandria, Baton Rouge and Slidell there is no fence, unless you are talking about the big 'box' with doors that holds the inverters and battery packs. Fences have been put in in locations where there are safety or ingress and egress problems. The key components are the several charging stations (red and white with 'Tesla' on them), the enclosed inverters and packs, a transformer (green in every case I have noticed), and a meter. The transformer is usually, but not always (Alexandria's is a half block away), immediately adjacent to the other components. In Shreveport, which I followed the closest, once the construction was complete, clear plastic bags were put over each of the charging stations. At that time they did not have charging cables attached. Not long after a Tesla technician arrived to test everything and turn the supercharger location on. And, of course, the charging cables were attached (I do not know whether that was done by the Tesla technician or the construction crew). Independent contractors (Pearl, Shreveport and Alexandria's contracted crew was out of Mandeville, LA). Once the technician completes the testing, he or she turns the location on.
