Many times I have stated (Usually in electric heater threads) that I do not trust those Quick-Box type outlets (The kind shown in the original post.
NOW you can see, with your own eyes, WHY.
When you and maybe a few others on the RV forums have said this, I was skeptical at first and believed that because they are CSA/UL approved there is nothing to worry about. What I hadn't appreciated in the beginning is how easy it is for a factory to mess up installing them and what the lack of inspections to ensure compliance with the NEC can do.
Besides that, if you look closely at these SCDs, a round copper wire is pushed into contact with a relatively thin "stab" type terminal while a conventional residential type recept. with side-wired screw terminals has a much greater surface contact area. In this regard, I would say a side-wired recept. (in an outlet box) would be a good upgrade for any locations that will have more than just occasional, short duration, intermittent loads like say in a kitchen and esp. for a recept. that will have an electric heater plugged in. I don't know (yet) if these are designed, tested and certified for continuous duty. For the few amount of recepts. RVs have and the little time needed to pull one out and inspect it, it can't hurt to maybe spot check at least a few of them.
