Q: I am wondering what happens when you have accidentally connected the negative cables to positive and the positive cables to negative. I have boat that has to two marine batteries and i am wondering if you were to do this will it screw things up and break things?: YESespecially if you have anything greater than a brief contact. Car and marine batteries are designed to deliver a huge amperage (that is why jumper cables are so thick) for a relatively short time. The best thing is to use a automatic battery charger used for car batteries which usually has a reverse polarity light on them that flashes or beeps if you accidentally hook up the cables backward. Or hook a multimeter to a known battery , like a AA battery with the positive terminal labeled, and put the red lead of the multimeter to there and the other lead to the other end of the AA battery. If the digital readout is positive 1.5V or so then measure the marine batteries with the same red lead and if the multimeter shows a positive direction then you know you have the positive terminal. If the multimeter has a negative voltage, then you know you have to reverse the cables

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: Here is the deal. I am majoring in Software Engineering. Which includes a fair bit of coding. I wanna be that guy who can make a robot or a Cell phone or Mp3 player or some sort of gadget. I want to do a dual degree with software engineering. So that i can do the software and make the device. So the plan is like this. If i make a robot i can write code too to make it move and all so that just eliminates 2 minds work. So i want to know which is the appropriate branch. Electrical or the Mechanical.What is the diffence between the two. I went to a college a few days ago and the guy there had made a robotic car. I forget if his major was EE or ME but he was doing Computer science minor. Can someone tell me what it could be ?? I want to make electronic devices. So like you can say that i want to make an iPhone sitting at home all by myself. Which 1 should i pick.Thanks a lot!!!!!!!!!: Look it up.

Q: can i sell magnetic contactor transformer 24vand where ?: I sell my old, worn out sneakers on OKorder. I try not to think about what the buyers are doing with them. I never touch Craigslist. If I sold something there, I'd expect the buyer to show up, cut my throat and take the item.

Q: for my hair dryer and other electrical equipment: Its a 3 pin plug herenot to worryjust get your stuffyou can buy a converter herealso electricity is 110V. so be mindful of that as well.cheers

Q: I was thinking of making a video game collection, I allready have a big one but only containing systems and games with CDs. But no collection is complete without the retro NES or SNES or the old school consoles with cartridges. My question is where would be a good place to store them? Because god knows how difficult it is to find a complete set with the box and Manuel and everything so I'll have to deal with just buying the cartridge. If you could help out I greatly appreciate it!: you always wanna store any kind of electrical equipment in a cool dry place. when it comes to Nes stuff same thing, if you really wanna make sure they will be good to go use a tote container or plastic cooler. something with a sealable possibly water proof lids. i have all my nintendo stuff sitting in a red igloo cooler in my storage unit. it has been there for over three years now and nothing wrong. just make sure you use a qtip and some alcohol to clean the pins up nice before placing in any system. you dont wan any dust that might have collected to go inside your machines.

Q: 20 ft. off the ground,miles of steel rail supporting it, thousand's of gallons of diesel, electrical equipment all around.: Safe. You are surrounded by metal which forms a pretty good Faraday cage. The loco is well grounded via the rails. Apart from the bang of thunder you might not even notice the lightning. The Diesel fuel is in a steel container under the loco and even better shielded than you are.

Q: i was finding a place for the two in my room but i dident want to set them next to each other. i was thinking that maby their are magnets in one that will ruin the other? so i was just wondering if its okay?: once you're going for all times like image layout, choose for the PS3. PS3 grow to be released AFTER the Xbox 360, so PS3 is possibly extra as much as date in assessment. Killzone is totally unique in trouble-free terms for the psthree so as that's slims only a dash distinction in case you like enjoying that game. I have been given the two consoles, the xbox is for my bro, jointly as mine is the PS3(jointly as each now and then i'm a working laptop or laptop guy). Get the PS3 and get battlefield 3! the two magnificent in offline and multiplayer gaming!

Q: I dont understand how charged particles in the sky would effect the electrical system down here.: It couldn't. Solar flares happen on the Sun. Some solar flares trigger coronal mass ejections (CMEs). If pointed in the right direction, some CMEs reach Earth. Most CMEs are deflected harmlessly by the Earth's magnetic field, causing auroras. Approximately once a century, there has been a CME powerful enough to penetrate the Erath's magnetc field on cause induction in electrical grids: telegraph lines in 1859 and Hydro-Quebec's transmission lines in 1989. Now that we are aware of the problem, warnings are issued and precautions are taken.

Q: I own a manufacturing facility in NJ, I have an electrician on staff. does he need to be licensed? can he run new wires and install panels if inspected? it is only work within our building.: As long as the work meets the NJ building codes, is inspected passed, I think you're OK. Personally, I would want my staff electrician to hold a valid license.
