Q: and how does its work?: It will basically provide safety protection from electrical shock. Occassional large electrical equipment may become temporarily energized --- maybe a down power line, or by accident. By grounding the equipment, the earth that you are standing on, and the equipment will always be at the same voltage. Therefore, even if the equipment becomes energized at 25000 Volts, the ground you are standing on will be at 25000 volts as well. So there is no potential difference and therefore, no electrical shock. Without the earth connection --- there would be a 25000 Volt potential difference, and you would suffer severe electrical shock, or even death. Excerpt from Wikipedia: Ground or earth in a mains (AC power) electrical wiring system is a conductor that provides a low impedance path to the earth to prevent hazardous voltages from appearing on equipment (the terms ground (North American practice) and earth (most other English-speaking countries) are used synonymously here). Normally a grounding conductor does not carry current. Neutral is a circuit conductor (that carries current in normal operation), which is connected to earth (or ground) generally at the service panel with the main disconnecting switch or breaker.

Q: 1. what is electrical and wiring system?2. what are the factors to be considered in designing an electrical wiring system in buildings?3. what are the possible ways of saving energy when designing an electrical and wiring system in buildings?i just need the experts opinion about this.thanks!: A building electrical system includes all of the equipment and wiring designed by the electrical engineer. This begins at the utility power connection and includes the service entrance equipment (meter base, current transformer cabinet and main disconnect switch), a main distribution panel (main breaker panel or main switchboard), and branch circuit distribution panels. The electrical system includes all wiring from the connection to utility power to connections to all electrical utilization of equipment. The electrical system also includes building lighting and lighting controls, building premise wiring for computers, computer hub room equipment, security systems, public address/broadcast system, keyless entry system, fire alarm system, and standby and emergency power systems. The main factors to consider is square footage of building, type of occupancy, number of occupants, and applicable local codes, the number of floors in the building, location of exits and stairwells. These considerations are used especially in determining what voltage with which to serve the building and size (ampacity) of service entrance and main distribution panel. These statistics are also important in the design of the fire alarm system. The main ways to save energy is through use of occupancy sensors and daylighting controls for lighting (the latter assumes windows or skylights for introducing daylight). These controls will keep the lights off unless specific areas are occupied, and lighting along with HVAC are the largest electrical loads. Energy costs (both electricity and heating fuel) can often be significantly reduced by incorporating CO2 sensors and variable frequency drives to control air handlers (large fans) rather then running them continuously at a rate to support maximum building occupancy, as is the case in many buildings.

Q: I found that there was a steady stream of ants (I live in India, and it's summer) flowing into my fridge, water cooler, keyboard, scanner, ups, and god knows what else and I can't understand why ! I have a feeling it's to do with the electricity itself, certain events have convinced me of that fact, but I would really like to know what's going on.: This Site Might Help You.

Q: i'm from the UK and i want to take my GHDs, camera and phone charger, what kind of plug do i need and where can i get one, im going sunday: Cuba’s electricity is 110 volts, 60Hz, but most hotels and resorts have 220 volts. Electrical outlets take flat plug prongs. If you’re bringing an electrical appliance, you should check the resort specs before you leave to see if you need an adaptor or converter. You will need an adapter/converter specifically for digital equipment. They're slightly different than the regular adapters for hair dryers, shavers. It's not true that you can take those with you and use them. People from everywhere travel to Cuba and use their cameras, recorders, phones, etc. Most travel, hardware, and department stores will carry these.and electronic stores for sure. See the links below for descriptions of which plugs are for which appliance. This one may be good for what you're looking for: valuemax .uk/product_detail Be sure to take rechargeable batteries as you may not be able to find those there easily or inexpensively. Have an amazing time in Cuba.

Q: explain the difference between an insulator and a conductor: the simple explanation is that an insulator does not allow the flow of electrical current, while a conductor allows the flow of electrical current. typically rubber and plastics are used for insulators and metals such as gold and copper are used for conductors

Q: I was wondering this, as I'm a smoker and never smoke in the house (due to owning expensive computers and such).Would the vapor from an E-cig be safe around electrical equipment? I would presume no, since the water vapor instantly evaporates after being breathed out, as apposed to smoke which lingers around and is rougher than air, which overtime damages fans and circuitry it passes over. Thanks for reading.-Karu: Very dangerous

Q: Hello all!I know this is a crazy ideaBut I wanna try and build a mini automobile where a person could travel here and there :D I've already planned this but what are the basic requirements I need to engage in this project? I mean apart from the basic structure of the system, what are the main electronic devices and mechanical equipment I need to engage in this? I haven't done anything like this before but I think I have adequate experience. If someone could explain the basic concepts to build a mini automobile with the requirements I would be very grateful :)Thank you: i'll tell you my Electrical point of view, you need to calculate the maximum load, and speed and choose the rating of the DC motor, and of course you need to design a driving circuit to control the speed of the motor, u need a gear to reduce the speed of the motor and get higher torque, that's so difficult for you look for something easier :P

Q: Greetings, I've noticed that my electrical power company is constantly sending me a reports on how much electricity I am using with respect to my neighbors, kind of trying to get me to use less energy. I figured that if a company is in the business of selling something, it might as well encourage you to use more than you really need.Why is my utility encouraging me to use less electricity? Is it because they feel there's going to be a backlash against the industry once the word gets out that utilities are big drivers of global warming, and they are trying to do damage control ahead of time.Remember, we live in a capitalistic society where maximizing profit is key to keeping investors happy. I can understand the water company asking me to consume less water, as water is a scarce resource. Coalwe have lots and lots of it. Enough to burn for a few hundred years.: Correct, revenue - expenses profit Building more plants or buying from other utilities is an expense. So, pretend that you are the electric company. Let's call it Jose Electric Company, JEC. So, JEC has to provide electricity to 5 million customers. They use about 1,000 kilowatt hours each per month. That comes up to 5,000,000 customers times 1,000 kw 5 billion kw-hours. If you could get them to cut usage then you would not have to build more power plants. Power plants used to be expensive, now they are very expensive. Your friend, the govt, does not want you to build plants that use coal. They are not keen on other fossil fuels. This year they like solar and portable nuclear plants. Yes, portable nuke plants. Till the political and regulatory environment gets a little more stable, it is easier to cut demand rather than build more production. On the other hand. Notice that within the last couple of weeks that 2 new nuke plants announced their start of new reactors. Looks like 1 was in South Carolina and 1 was in Georgia. It would seem that they have foresight, experience, skills, management and money to make sure supply is there for the demand. We also have enough natural gas to burn in jet driven turbines, many years. Water scarce? Where did the water go? Did it leave the planet? Water problems are logistics and not really shortages, are they?

Q: I'm enlisted and my MOS is 15Y (Armament/Electrical/Avionics Repairer). I'm going to BCT on 20100203 and AIT right after at Ft. Eustis. I'm excited about learning about armament and avionics. I feel proud and privileged to have a chance to work on the numero uno attack helicopter in the world. I want to know how hard it is to get this MOS(no disrespect to other MOS') I have 3 questions in regards to this1) How does 15Y training look like and can I get a head start for the subjects taught right away.2) I would like to go overseas as a first preference, a warzone where I'm needed the most, but also what is the best non combat station to serve in for this MOS overseas and in United States respectively.3) I'm a college graduate(non-citizen pending citizenship in 6 months) and I would like to go to OCS by the end of 2010. Please let me know the best route to do it.Thank you.: For the best answers, search on this site

Q: Hey Guys !I just finished High school and I'm quite certain that Engineering is my first choice, however, I'm still a little bit hesitant. I'm choosing between electrical or mechanical! I think I like both majors and as far as I know Mechanical is the science of moving objects where you can get more hands-on experience , while electrical engineering is more imaginative. You can't really see electricity , thus it's more challenging ! To be honest , I like challenges but I don't want to end up regretting any decisions! Can anyone give me any insights , advices or opinions on both of majors ! What I'm going to study , what can I do , anything that could practically help me decide ! Thanks in advance: I believe you grasp the essential intellectual difference between the two fields. In the study of both disciplines there are laboratories where you build things. In electrical labs you build circuits, and in mechanical labs you use lathes, drill presses and milling machines to build mechanical devices. When you are out of school and working, you will most likely not be doing anything hands on except inspecting equipment, systems and facilities. Your principal work will be analyzing, documenting, reporting and creating design/construction documents. I had an orientation to both fields (mechanical and electrical) as from the time I was about 13 I rebuilt engines in a machine shop and loved to build all sorts of mechanical things on a farm. But I also liked to design and build receivers, transmitters, amplifiers, etc. Ulitmately, I was attracted more to electrical engineering because it seemed more esoteric and mysterious; but I think I would have been happy and successful in both fields, and possibly even in structural engineering. These fields apply math and the other sciences, and require creativity to find ideal solutions. Civil engineering seemed too mundane to me.
