I am installing some outlets in my new pole garage. I am trying to to avoid drilling holes in my 6"x6" posts to run wires. I plan to put an outlet on each post. I am using the single gang plastic outlet boxes that just nail to the side of the post. I was wondering if I could run the wire straight up from my breaker box. Then across the top of my header. At the top of each post (above the ceiling) I was wanting to put a junction box. In each box I planned to pigtail three wires. The wires coming from the panel, the wires running down the pole to an outlet, then a wire running to the next post on top of the header. Does this make sense? It is kind of hard to put in to words. I guess my main question is about the junction boxes. Is it safe to have three wires pigtailed together with wire nuts then wrap the nuts in electrical tape for extra safety. Each junction box would have three hot wires pigtailed, three neutrals pigtailed, and the copper grounds pigtailed. Thanks in advanced for any help.
