Q:How can I ensure my computer is properly backed up and the back-up files are unaffected by the sun? Would putting everything on CDs and DVDs work? Which would be better; an external hard disk drive or an external optical hard drive or jusr DVDs/CDs?: NASA aren't predicting any 'once in a generation solar storm'. They are merely saying that warning and protection systems should be in place - a perfectly reasonable precaution. In fact NASA are predicting the next maximum of solar activity in 2013 to be less intense than the last in 2001: solarscience.msfc.nasa /images Solar activity can produce induced currents in transmission lines, very occasionally leading to problems in electricity supply and distribution, so the worst that might happen is a power cut. The Sun does not directly affect your computer or any other electrical equipment. You certainly don't need any lead casing. Having said that, backing up your computer files is never a bad idea. No medium is completely immune to damage, whether heat, damp, power surges or physical damage so maybe you should put your more important files on both DVD and an external drive.

Q:I might be starting a job doing industrial electric, and I want to make sure I can read the blue prints good. I am recently graduated from high school and have a vo-tech background in electrical, only no blue print reading. I know how to read schematics, ladder diagrams, and residential blue prints, but how different are industrial and residential blueprints? Does anyone know a site where I can look at some industrial electric blueprints? I know when i get there they will be able to teach me how to read it, but I figured I would try to save everyone some time and see what I can figure out before I get there.: What you really need is a good book. Get a copy of Ugly's Electrical References by George V. Hart. You need to know what the symbols mean as to what they physically are. Those blue prints won't be a whole lot different in some respects from what the residential blue prints are. Ugly's will prove to be an invaluable aid to you. When you get the job, if you don't understand something, ask, they expect you to not know a lot of things. You are going in as an apprentice, so you are there to do a lot of hard work, and to learn as you go. If you are given the opportunity to go to any schools, go. If you should get the chance to go to ant schools for fiber optics, go, in fact, seek it out for yourself, even if it means night school. The pay is great, and there is always a demand for those who are trained in fiber optics installation, and repair.

Q:ever had your electrical equip. tripped off by GFCI RECEPTERSdid it damage your hard drives, toasters, microwaves ect.?: I saw your other question about freezers and GFCI protected circuits. What are you up to? GFCI protected circuits will not harm your electrical equipment or appliances. When they trip it is the same as simply turning off the electricity. No problem. I think you may have issues other than what you are asking.

Q:I have just recently started getting electric shocks at random times when working with my tank. The first time it happened i was wearing a rubber glove (which i thought would block electricity in the first place) i put my hand in the sump and it tore through the glove and shocked my whole arm. The next day i was using the net in the tank itself and got a big shock, then the same thing happend to my brother, my girlfriend and my friend all at different random times. It feels like one of those trick handshake or trick lighters that people have but it hurts way more. Basically the shock runs through my arm and into my chest, leaving my arm numb.I have a 72 gallon bowfront saltwater set up with live rock, about 15 fish, the whole deal. I have the coralife 260 watt compact fluorescent light hood with moon lights attatched with plastic legs on top of the aquarium over the glass canopy. I have an 850 gph pump in the sump, a 300 watt heater in the pump and a protein skimmer in the sump.: it amazes me the fish are'nt dead first.unplug everything,and inspect it closely.my guess the heater is the culprit,throw them away after 1 year,even submersiblesstart to show moisture in the tube,powerhead motors are incased in epoxy,that does'nt mean some thing could'nt be wrong with it [cord coming loose,hairline crack,ect.keep all original packaging and receipts,send suspect materials back.is water running down a cord?use drip loop,and ground circuit fault interrupters,not hard to install,directions come with it or buy a cord,with one from fostersmith,ect.i've kept saltwater for 15 years,had 2 problems in that time a heater plugged it in it went powand not drying the hands.good luck!also the heater may only shock when it calls for heat.if it's not heating it doe'snt shock.hang the fixture,don't use the legs.

Q:I don't intend to get a job with this but it would be good to know some things about it since everything runs on electricity now.: do not be lazyread a little about electronic troubleshooting like . tracing voltage .tracing currenttracing waveform with oscilloscope. then start repairing electronic boardssurely you will earn more money

Q:I have a dental Lab in Europe an want to move it to the States, maybe. Some of the equipment rates as high as 4kw, and the the total maximum draw is 15 kw for the whole lab. Can I wire a secondary breaker box in a building in the United States that is all 220?: You should check all of the equipment to see what is 50hz or 50/60hz (can run on both). Also here in the us we use 230v 3 phase(3 hot legs) for commercial applications. The UK uses 1 phase(1 hot leg) I don't know where you are located.

Q:Could someone tell if if I translated this paragraph correctly? Does it sound grammatically or stylistically good? The last employee leaving the premises must switch off the light and electrical equipment (except those that must run around the clock).: The last person to leave should turn off the lights and electrical equipment. It is so obvious that electrical items that are on 24 hours a day are excepted that it does not need to be said.

Q:doesnt it release toxins when heated or burned, also why do they use it in cookware, I thought it's supposed to be some high quality plastic that resist heat and deterioration by chemicals, and isnt it also very expensive, but then you see it used on cookware and a bunch of other cheap crap, for example teflon tape, you can buy it at the 99cents store, it cant be that great if they sell it there.: Teflon is used in laboratory equipment and electrical insulation for its resistance to heat and many chemicals. Teflon is a trade name for a variety of fluoro-chlorocarbons, though it's pretty much become a generic term now. It's expensive compared to many other plastics, but some types are fairly cheap, and anyhow, there's not much stuff in a roll of teflon tape or a teflon frying pan. It starts to outgas at around 450°F. Technical applications are usually careful to keep it below that, but in the home, preheating an empty pan can take it to 700° or more, releasing enough toxic gas to kill your pet bird.

Q:Assuming that it is safe to do so as far as people not getting hurt, will it damage the electrical equipment?: it can damage certain appliances, yes. for example, it probably wouldn't harm your toaster, but it's probably a bad idea to unplug your PC randomly. you might lose valuable information, files, and you might even cause the computer to act unresponsive or even crash. it all depends on the appliance.

Q:I am doing a project on electronic baton.I want it to look exactly like baton used by professional orchestra conductor.I stored the electronic components inside the handle of the baton.The problem is the space is very limited.The maximum diameter of the handle only about 18 mm.I need to choose a battery that also stored inside the handle.I want the battery that could work for long time.However what I can see the coin battery that is small only have small energy in it.It will only last for less than 1 hour.It is not good for new product.What can I do to maximize amount of energy so baton can work for longer time? ideally 10+hours or minimum of 5 hours and can fit inside small handle.I dont want to use external power cable.Hope you guys can help me.Really appreciated all of your helps.: Lithium batteries tend to offer best size to power ratio right now. They are available in rechargeable and disposable. Take a trip to Walmart bearing in mind you may find something you like that is designed to go into something else such as a replacement battery for a cell phone or camera etc.
