Is there any way to have wall fixtures installed above my fireplace mantel. It is not pre-wired and I wondered if it can be done now. I could use recessed lighting in the ceiling, but I would rather have wall fixtures. Also can wall fixtures be wired for plugs?

Hello to all. I am wondering about the necessity to connect or not connect the neutral and the safety ground together at the breaker/fuse box in the following situation. My home's electrical service entry is a bit complex and is in the following order (from the outside in): 1 from pole transformer to 200 amp main disconnect with fuses (here, neutral, earth ground and safety ground all meet). 2 from 200 amp disconnect to meter socket (yes, my meter is AFTER the main disconnect!) here, by meter box design, neutral and safety ground meet again. 3 from meter box to 200 amp splitter box (neutral and safety ground seperate). 4 from splitter box to 100 amp disconnect(neutral and safety ground seperate). 5 from 100 amp disconnect to fuse box (presently neutral and ground seperate; this is the subject of my question). Actually, from the splitter box there are two 100 amp disconnects and two fuse boxes, but wired the same way. My feeling is that since earth ground and safety grounds are already meeting at two places early on in the chain and then there are several other boxes before I get to the fuse box, it would be best to leave them seperate at the fuse boxes, as if they were sub panels. Does this make sense ? I also want to specify that between the 200 amp disconnect and the final fuse box, there is about 12 feet of wire of the appropriate guages, and the safety ground that runs alongside (and connects to all the box's frames) is a 6 guage bare wire, taped up where visible inside the actual boxes. One last question; in the near future, I want to remove both 100 amp disconnects and fuse boxes, and replace these with a single 200 breaker panel. Should the neutral and safety grounds still stay seperate in this case (with one less intervening box) ?
