Q:I'm about to take an automotive electronics class at college but I'm just curious, what are the basics? Say I want to wire a police scanner or some type of lightbar into my car's electrical system. What would this entail? I'd have to pull away body panels, run wire, and hook it into the battery? What about fuses, safeties, etc And also how could I hook my police scanner into my speaker's system?
Fuse blocks in cars often have SPARE (usually disused in some particular model) positions with wires already attached and within the wiring loom, with nothing connected to the end. Knowing what the intended accessory was, might allow you to connect something to its unconnected end, and always, the negative return is the car's frame. The circuit must be capable of carrying the current required. Some of these spares may be connected via the ignition switch, some may not. The next alternative is to run a new wire with a fuse inline, at the supply end at least. It is good practice to fuse the supply end, then have a further fuse at the accessory end (most accessories will already have this). The wire can often be run along and fixed to the existing car looms, passing through the firewall where the loom passes through. Again, negative is anywhere convenient on the car's metal frame. A quick and simple connection is the cigarette lighter, if fitted. Just procure a plug to replace the lighter. It can supply a fair current. So far as connecting a scanner to the existing speakers, I suggest you don't try to, unless the audio/ radio system has an accessory input. Maybe a bluetooth connection might be used, but really, the scanner's own speaker should supply the scanner sound. You can also connect accessories by splicing into existing car circuits, but I would suggest you do your college course first! You really need to understand current and wire sizes and fusing (not to mention basic circuitry!), before splicing into existing wires.
Q:Context:Provide rated electrical equipment where combustible dust is present.
Safety rated by an organization that issues such ratings such as UL or FM
Q:Electrical system in a residential building. When we use any equipment on one phase the lights on that phase dim down but and the same time the lights on the second phase become brighter.
the neutral of the building is disconnected from the utility mains neutral, that's why you are getting different voltages for different loads call a good electrician to reconnect the neutral And this problem can only happen when the building is connected with a 3 phase electric supply
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:I know converters exist, but are they safe for high end audio equipment?I have a digi 002 rack, grace M101, and great river pres.would a power conditioner help me?
No the third prong was designed to be grounded just in case there were slight surges or worse faults in the power circit. By connecting the cases of electrical equipment to earth, any insulation failure will result in current flowing to ground that would otherwise energize the case of the equipment. A proper bonding to earth will result in the circuit overcurrent protection operating to de-energize the faulty circuit.-Wikipedia In otherwords have that ground keeps the current away from your equipment when it faults
Q:I would like a serious answer from a professional who would know about these things from being part of the military or etc.When the air burst missile exploded, everything electrical stopped working. At the end of the movie, the girl asked if the phones are working and the guy replied Are you kidding, they'll never be phones again.Is that a true statement? Can anything electrical ever work again?? Or did he say that because the world at the time in their point of view looked unrepairable ?Also, if I was in a well constructed fallout shelter with all my stuff and I wanted to save Computers, TV etc. will it get affected from the outside air burst missile? (I know a lot of people are gonna yell why keep those when you can't use electricity again after a nuclear war 1, I just wanted to know, 2 I could use them in the shelter if I have Generator batteries for room lighting and everything else)
You should be concerned about protecting yourself,not your toys.A well constructed shelter (fashionable in the 50's)would keep you out of the Blast(maybe)but would not save you from the Gamma rays.Everything would be contaminated for hundreds of generations.Nothing would grow,water would be undrinkable.When and if you emerge from your shelter,what and who would you find?Back to the Stone age.Have you seen the series on Discovery,Life after PeopleIt would be awful if you survived.
Q:I'm a physics students and often come up with seemingly stupid questions I can't really find an answer to. If the human body acts as a resistor of around 100 kilo-ohms or more, how is it that I could die by grounding myself with the hot terminal of an electrical outlet?I understand that the average current flowing through me is the product of RMS-voltage over resistancebut this value doesn't seem NEARLY high enough to do any damage much less for me to detect.Thanks!
Mr. C. has an excellent answer. I might also add that as an electrical worker I find it very important to make sure that when I work with electrical circuits and safety equipment that I try and eliminate a flow path from live to ground that can pass through my heart area. We always use safety equipment and follow procedure but at times you have no choice but to get very close to energized exposed circuits. They can and do bite. I have been known to take an extra step and insulate exposed energized areas that are near my legs when I am working with energized circuits above my waist.
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:has to do with electrical control
It is the National Fire Protection Association standard for electrical safety. Just do a Yahoo search for nfpa 70 and you will find it.
