    When a product is made in the US it goes through a battery (excuse the pun) of failure tests. It has to first not fail and then if it does fail it can't hurt the user. IMO not getting shot 49 out of 50 times would not be classified as being safe.

    I'm pretty sure you completely missed the point of what I said.

      I might have. Let me get another cup of coffee and re-read your post.

        Unless you are running at the extreme limits, I (and I'm not speaking for midnight) would mount it any way you want. But I'd put it on a thick aluminum plate to help act as a heatsink. The classic has no external heat sinking, fins and pins are all inside with 3 screaming fans that cool it, no convection at all, in my opinion,

          Nope, no one said a word about cable heating. But since you brought it up you cannot use MTW wire in any building as power wiring or anything in wet or outdoor applications. If your project were required to be inspected, your cable and terminals would fail and have to be replaced. Kind of all of our points, you do not listen or understand what you are being told.

          You are wasting your time, no one gives a damn what you think is safe or not. Fact is your methods and workmanship are poor, o not meet any known safety or comply with any known electrical building codes. No inspector, technician, installer, Osha, NFPA, Insurance company and engineers give a damn what you think is safe or not.

          As for me, I do not care what you do, nor do I think the Mods give a darn what you do. We do not care if you set something on fire or hurt yourself. You burn something up or hurt yourself no problem for us. But if you think you can come here and other forums and say you are right and the rest of the world is wrong is not going to fly, especially when it is dangerous and demonstrates clear neglect. The forum owners can be held liable for their content and allowing you or others to promote unsafe practices.
