Music,
You misread my intentions. My post was meant to gently steer you to the DIY site for the questions you posed. I don't know how I could have been more tactful.
When I read your reply, it bugged me that I may have come across the wrong way. I was going to let this post just go away, and assumed we would meet again on other threads.
I also wanted to spare you the frustration of dealing with some of the inevitable barbs you would have encountered being a new poster on the site with questions that sound exactly like ones a homeowner would pose if he got through the "front door" undetected. Once you are around here awhile you will see exactly what I mean. GUARANTEED.
I have absolutely no doubt now you are a legitimate contractor, but by your own admissions, you are not an electrician. As you know, true GC's (who are referred to sometimes around here are "paper contractors") are not expected to know the details of every trade. But you are contemplating biting off a task that if done incorrectly, can cause people to get hurt. (Like your family for instance)
In this post, you ignored a simple question posed by 480 Sparky who has more electrical knowlege than I could ever hope to attain, and he asked again, and you didn't respond to his question which could have laid the groundwork for which code you fall under as well as the local amendments.
Your electrical plan seems to summarily pass my approval but I don't know all the details either, so I would defer to a licensed electrician who has had the opportunity to physically look at what else this previous owner may have screwed up.
I hope your reaction to my well intentioned post has not soured you on this website. It's a terrific site to ask questions, help fellow contractors who are experiencing something you have been through and have figured out out to handle, and to just blow off some steam with like minded guys.
I hope there are no hard feelings, and I look forward to seeing you around here.
