roniheels Posted December 5, 2008 Share Posted December 5, 2008 United States - Residential is 240 volt single Phase. - split into 3 lines consisting of (2) 120 volt lines and a neutral line. This provides both 120 volt for standard wall outlets and combined 240 volts for appliances such as A/C, ranges, dryers and such. There will be review on Thur and exam on Friday so, Pay Attention. Jen Oh great! Now we have take a written test. Shocking! (ouch...no pun intended). Link to comment Share on other sites More sharing options...
danielp6406 Posted December 5, 2008 Share Posted December 5, 2008 Here in Europe we've got three-phase 3x400/230V for most houses [apart from flats in blocks] and commercial / public buildings. The power is transmitted through the urban / rural areas by 3x15kV grid, and stepped down with local transformers. Malls, factories and other large objects have their own substations with transformers; for a group of houses / blocks, there's one nearby substation. Elegant :-) A little bit "out of topic" but see below more details about us in North America: We also got 3 phases power here in Canada and USA but not to supply single house. Canada 3 phases power is 208-230/575 Volts. USA is 208-230/460 Volts (60 Hz). High voltage grid in small neighborhood is 14.4 kV. Larger cities is 25 kV. In the Canadian province where I live, the voltage for long distance power transmision is 735 kV. (Now you may know from which province I am from) Back to the subject: I was very happy having found this forum to discover I was not alone (or crazy) wearing high heels Link to comment Share on other sites More sharing options...
