Quote of the Day
The most beautiful people we have known are those who have known defeat, known suffering, known struggle, known loss, and have found their way out of the depths. These persons have an appreciation, a sensitivity, and an understanding of life that fills them with compassion, gentleness, and a deep loving concern. Beautiful people do not just happen.
— Elisabeth Kubler-Ross
For years, I have mounted most my electrical outlets "upside down" (see Figure 1) – by upside-down I mean the ground slot is up. Recently, I have started to see more folks orienting their outlets this way. I see that Finehomebuilding Magazine and the Journal of Light Construction (JLC Field Guide) recommend this approach as well. However, it is not required by the National Electrical Code.
I started doing this when I saw a child drop a metal object onto a loosely plugged in cord. With power and neutral wired as the top slots, the metal object shorted and created a spectacular flash. Fortunately, no one was hurt but the outlet and plug were both damaged. Having the ground slot at the top means that a metal object dropped on a plug is far less likely to contact the power contact. Watching what happened to this child drove me to reorient many of the outlets in my home.
Note that some products (e.g. my refrigerator) have cords that tend to pull out of outlets that are wired with the ground-slot up. These outlets should then be wired in the conventional manner (i.e. ground-slot down). These outlets usually are in places where metal things are not likely to fall on cords plugged into them.
The same logic applies to sideways-mounted outlets (Figure 2). In this case, the neutral slot is mounted up.
