Why don't USA (and Thai) wall sockets have a switch in them?

 This rant reminds me of the "circuit of death". No, not the Formula 1 circuit, neither the Mortal Kombat not Body Building stuff. I mean about the electric circuit. Imagine you (general you) have a long corridor or a staircase and you want to have a light bulb in the middle, but have the possibility to turn the light on and off from either sides of the dependency (staircase or hall, etc). There are many ways to connect two flip-switches to do so. One way is shown here (picture from wiki common license**): And more are shown in this video, which you should watch before reading further: Or, yeah, I know, you have no time for videos, at least click this link and read about, it takes less time. Now, everything is fine, but there is a big "issue" with that circuit, you have to run a lot of wires from one side to the other, and back to the plug. So, some German guys in the eighties "minimized" the number of wires you need, by using the following circuit: This is "much better" because, obviously, based on the fact that in your house you only have one phase (so the line and neutral are the same in all rooms), you have exactly the same functionality, and you only need to run a SINGLE wire along the staircase or the corridor. The only problem in that: you may have the situation in which the light bulb is off, but it is still connected to the hot line! (on both sides, actually!) This circuit became known as the "circuit of death", after few people died trying to change the light bulbs, and there was a law voted in Germany in the nineties (yes, they actually HAVE a law, voted by their parliament!) to interdict this circuit. ---------- ** that is how I found out that the forum makes a mess of displaying png files with transparent background, but too lazy to re-make the picture now, you can google the stuff Last fiddled with by LaurV on 2020-08-29 at 18:35 |

2. Are you joking right? Switch? Here most housed have no earth wired either! In my house (rented, lived there for 20 years) most wall sockets only have two holes, and those which have 3, have only 2 wires behind the bezel. In the room I keep the "big guns" (computers, always on, crunching) there is marble floor, and we kept it because it is "colder" than the usual wooden (parket) floor in the rest of the house, but if you touch the computer case without wearing shoes, you DO get nasty electric shocks (not dangerous, but enough to "surprise" you). Fortunately, nobody died. My family knows the rules ("always wear shoes!") and I did a lot of work to ground and insulate electric stuff we use (except for shower heaters, which, surprisingly, were always properly grounded from the beginning). Our factory ran for the first 10 years in the beginning (the end of the last century) in a rented building, former army storage house (till we did our current one) and we had a real WAR with the electric company and electric workers/subcontractors to make a proper grounding to that building, to ESD protect the production lines, etc. They still didn't understand why we need ESD protection, and I bet my life that now, after 20 years, if I meet any of them, they still don't know why.  That's not only Thailand, it is somehow, all Asia, they run on two wires only, unless somebody dies, then they... will change? No, they will party for a week ("look, that idiot died!") and then forget, start from scratch, haha. But they can do a very good job if you can make them understand what you need, and why.

Ungrounded metal is forbidden in my lair. Anyone found installing anything without ensuring all exposed metal is grounded is re-educated.

Just some additional information for those who are not familiar with the US electrical system. |

We installed Windows to do some benchmarks. In Blender we told it to use the GPU via OpenCL. And it worked!  We have only the basic AMD Radeon driver installed. We made sure to watch the CPU (Task Manager) and the GPU (GPU-Z) and without a doubt it is using the GPU. |

Now that we (temporarily) have Windows running we are running various utilities and benchmarks.
If you have a particular one you would like to see just post about it. Here is the memory info via CPU-Z. In particular, we are happy to see that the memory is dual rank and that it has a 1T command rate. |
