as an electrical contractor with 38 years in the trade, i have seen quite a bit of bad wiring, device mis-applications, and downright dangerous shortcuts. also, as a long-time "student" of the N.E.C., i have joined this forum to offer any reasonable help, (keyword--->REASONABLE), as well as my professional opinion of the various "d.i.y." questions that are posted here. safety and quality workmanship are the only 2 criteria i plan to adhere to. when a "d.i.y.er" asks me about a project or problem he has, the first thing i do is look at the potential danger involved, then, i look at the complexity of the job. if, in my opinion, you need to leave it alone and call a pro, i will tell you so, not becauuse of any personal feelings i may have for you, but for the safety concerns i have. there is an old saying that i live by every day, when i walk out my door to go to the jobsite. the saying is, "there are bold electricians and there are old electricians, but there are very few old, bold electricians."
have a safe day!!
