What country is a better question. The part you are missing is "wall switch". This is a switch near the door that controls a receptacle somewhere in the room. (for a lamp) It is not a switch right on the receptacle. Makes more sense to have the switch no the socket, then it's clear what it's for and where to find it. Yeah, that works real great for a floor lamp. When you enter the room in the dark, you can move the sofa, crawl behind it, to turn on the switch for the floor lamp. Idiot. You have the choice to leave the socket switch in the on position. Some people like to switch, say, a tv completely off and not to leave it on standby. I remember when VCRs came out, it took years to convince my dad it was easier to leave the VCR on all night than to reset the ****ing clock every time you wanted to record something! Ha!

Every genset I ever installed was a 60hz unit that spun at 1,800rpm. I wonder if a 400hz genset would have to spin at 12,600rpm or have some sort of frequency converter system on a genset spinning at a lower rpm?

Smart TVs are not "off" unless you pull the plug. Monitoring for software updates for one. It is still in there chugging along, about like your PC when it is setting on the desk top and no applications active. it is still going to draw something. Cranked up it can stream and process 1080 HD content so that makes it a pretty powerful PC. Cable boxes and DVRs do ned to be active when "off". I have measured the power consumption of a cable box and found no measurable difference between "on" and "off". BTW, these digital adapters I got recently don't have "off". The TV uses less power because the display and audio amp is off, That is about it. |

So why don't any countries use a much higher Hz? It probably has to do with the higher speed at which generators would have to spin and I believe there would be greater losses in the distribution system due to the higher frequency. Some long distance high voltage transmission lines are actually DC. ?(?)?

Interesting question. Tradition I imagine. Once you are locked into a frequency, changing is very expensive. Motors and clocks won't work for one thing.

I'm guessing a high frequency electrical distribution system would require shielding which would make it more expensive. I believe the generators would also have to spin faster. Every genset I ever installed was a 60hz unit that spun at 1,800rpm. I wonder if a 400hz genset would have to spin at 12,600rpm or have some sort of frequency converter system on a genset spinning at a lower rpm? The gas turbine APU's for aircraft can definately spin at high rpm so I'm wondering about the power units that the aircraft mechanics roll up and plug into the aircraft while they're working on them prior to flight. I suppose I have some research to do. ?(?)? [8~{} Uncle Power Monster The generator thing is just how they are wound. We had 400 hz MG sets in computer rooms for years.

I don't think propagation would be much of a factor either if the systems were designed properly. I'll go with 'tradition' as the major factor. Most 'end user' devices here are engineered with filters to reject harmonics of the 60 cycle system, or rely on the 60 cycle broadcast standard. https://en.wikipedia.org/wiki/WWVB |

That is not exactly true. We were starting to see it on big buses at 400 hz. They were replaced by fine strand cables similar to welding cable. These were handling around 60-100a tho. Once we got away from regular transistor logic and into CMOS the current requirements dropped and 400hz went away. |

This is for 120 Voltage source USA standard Receptacle. That's wrong. If the source hot is already in the receptacle box then the conversion is fairly simple. You only need to run another wire if the source hot is in the switch box. ***No you are wrong "Look what man is asking for" Comments has being made that is not convenient, if you enter in room need to go behind sofa to put lamp on. Yes it defiantly sound pretty stupid. But why one would need to do that Most of Lamps in USA comes with the switch at the bulb socket, some come in the base of Table lamps, or you can get sound activated switch or intrusion switch, any one comes in room the lights goes on, they are made with time delays built in to them for on or off, that are some remote ones that you not need do anything but plug it in. If you are going to use the lamp's switch then the location of the switch for the switched receptacle is a moot point since it will never be switched off. |

In fact you can change which way is on by which bottom hole you use.

You can get just about anything that is on the internet with it if you have the subscription and that includes most of the cable channels. Connecting it is as simple as adding your WiFi password. The setup wizard on the Samsung is real easy. You can also plug in a USB drive (hard drive or stick) and play your own movies and audio. Samsung will connect to your media library in Media Player but I have never messed with that. I just have a 2 TB drive that I sneaker net movies to as I get them ripped from DVD. My goal is to eliminate media played from little bits of plastic. I am just disappointed that Samsung can't take them directly from my file server without that WM business.
