Q:facility, electrical

It almost sounds as though you are asking about a manufacturing plant, so I will answer from that standpoint, This could be an Extremely long list, but I will limit it to major causes. lack of organization, both in personnel and materials inexperience improper equipment/under equipped lack of knowledge outside factors such as shipping/receiving

Q:Garbage disposal is wired into open electrical outlet down thru basement. Dryer is not vented outside, which is in the basement also, right next to this outlet. There is excessive lint from the dryer all over this open outlet that doesnt have a cover and the live electrical big thick white wire that you wire a house with is split down the middle then the raw metal part is inserted into each side of the outlet for the garbage disposal. If I pull this out to disconnect it will it spark? Shock me? Catch on fire? I want to do this because I am afraid it is going to catch on fire from all the lint. Is that possible also?I rent and I know the dryer should be vented, however it is all glass block windows and landlord has yet to fix it so please dont tell me to vent the dryer. thanks

leave all repairs to the landlord/ownerhe will blame you if something goes wrong during or after you touch something electrical.if landlord wont address problems in a timely manner than move somewhere else if possible.if you are concerned with the dust/lint buildup on the electrical socket then get a can of compressed air [ normally used to clear dust/lint from electronic equipment ] and use it to clear the socket without touching itbest to where safety glasses and dustmask while using the compressed air,will no doubt make a cloud of dust in the area that will take a few minutes to settle,but at least you will feel saferas far as venting the dryer,,they make water traps that you can vent the dryer into if there is no duct to the outside.buy one from home depot or similar store and follow the instructions.will reduce but not eliminate the dust and lint coming from the unvented dryer.dan

Q:I have a hanging, pull-string electrical light in my attic. This is very standard stuff. I would like to purchase an electrical device that will screw into the electric light and give me an electrical outlet. Think of this as a device with the base of an electric light bulb and an electical outlet instead of the bulb. I thought I saw one in a hardware store 20 years ago, but I have no idea if this product still exists. I can not think of what it would be called with a technical name when searching for one on the Internet.My business application is to be able to plug equipment into my attic rather than running the cord into the main house.

Electrical circuits in domestic homes normally have two types of circuits. One for the lighting and another for the power supply. You are not supposed to use the lighting circuit for power supply. If you do you may be in contradiction of local wiring rules. As a result if there are any unfortunate events occurring as a consequence you will probably not be covered by insurance. In other words, if you burn your house down from using the lighting circuit for power supply you have no comeback. Having said all this it is unlikely to happen. Lighting circuits have a lower amperage rating and smaller wiring cross section. So therefore they cannot handle too much load, you may find annoying fuse blows or circuit breaker trips. In conclusion, and as an electrician, I recommend you just have a power supply correctly installed. It isn't as expensive as most people think.

Q:1 explain the difference btween a conductor and an insulator in terms of the transfer of electrons. Why are problems with static electricity common in winter than at other times of the year? How could any of these problems be reduced?Why is cleaning dusting more difficult in winter?List at least 2 reason why you think plastic materials are used to cover the copper wires in electrical equipment.

1. In a conductor, electrons transfer easily from atom to atom. In an insulator, it is extremely hard to cause electrons to shift atom to atom. (edit) This means an electrical current cannot flow in an insulator, as electrons must move in a conductor. (end edit). 2. In winter, the air contains less moisture. Therefore static charges will not dissipate as quickly as they will in moist air, and are more easily generated. 3. For the above reason, moving dust particals can easily induce a charge in them, which will be of opposite polarity to the surface. They can be attracted back to the surface. Using a slightly moist cloth can help when dusting in winter. 4. Plastics etc. are electrical insulators. Plastic insulation is very easy to apply to a conductor by extrusion around the conductor, in a plastic extrusion machine. The material is heated to a suitable plastic constituency. Plastic insulations are NOT used in extreme heat or cold situations for conductors. If you live in the US, you will see lots of rubber insulated power leads, as plastics can get more brittle and fracture in cold conditions. Plasticity is the state between solid and liquid, which is where all plastics are worked. In fact, many materials other than plastics can be worked in a plastic state, even metals!

Q:Hi everyone!I'm currently enrolled in an electrical engineering course and I like it a lot, I just don't like the computer aspect. I actually really hate computers. I'm more of the other spectrum like the hands-on mechanical side. However i don't purely want to do mechanical engineering cause i do like electronics. is there a meeting point? should i major in electrical and minor in mechanical? or major in mechanical and minor in electrical?to make things worse i've always had an interest in biomedical enigineering but the biomechanics track. I'm not enrolled in that because i heard that its hard to find jobs in that field since it's still developing.opinions? advice? anything is appreciated:)thanks!

Well, with a mechanical engineering degree, you can do almost any other engineering discipline, granted you get a little more education in it too. Mechanical engineering is the broadest of the three fields you mentioned above; I've heard of of some mechanical engineers working in the medical device industry, so I would suggest mechanical. Electrical, on the other hand, is a whole other ball game. It deals with circuits and electrical devices,programming, etc. If electricity and magnetism from physics interested you, then I suggest looking into electrical engineering.

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 are referring to electromagnetic pulse. The strongest part of the pulse lasts for only a fraction of a second, but any unprotected electrical equipment — and anything connected to electrical cables, which act as giant lightning rods or antennas — will be affected by the pulse. Older, vacuum tube (valve) based equipment is much less vulnerable to EMP than newer solid state equipment; Soviet Cold War–era military aircraft often had avionics based on vacuum tubes due both to limitations in Soviet solid-state capabilities and a belief that the vacuum gear would survive better. On the other hand, the solid state PRC-77 VHF manpack radio survived extensive EMP testing. The earlier PRC-25, nearly identical except for a vacuum tube final, had been tested in EMP simulators but was not certified to remain fully functional.

Q:I am in need of some information where I can go to find information in medical literature regarding electrical shock. My precious (a young surgical RN) daughter-in-law experienced a serious electrical shock at work (in an operating room). To this point, I have not talked to her to get more details but she is still very ill from this. She has migraine headaches, abdominal cramps, tingling in her arm etc. I am very worried about her. Some type of equipment malfunctioned it destroyed the equipment severely shocked her. I am not certain of what tests she has had done all, as she is sleeping all the time from the exhaustion too ill to be up much. I just need medical information so I can give her to make sure she gets proper tests such is properly informed as to what all she needs checked out. She has never yet had children wonder if this will affect her eggs?Please help. She is too ill to research this my son is very busy away some.

If you say the baby is moving, and acting normally as he has been doing in the last few weeks, the chances of something being wrong is pretty slim. Also, like the others have said, please confront the restaurant employees or manager, shocking a normal person can be bad enough. But when you are pregnant at 31 weeks, its almost like planned abortion. Definitely confront them, as it could earn loads of compensation which could help with the baby.

Q:I bought a used printer but it did not have the power cable with it, but I have an old power cable from another printer. The only visble difference in the cables is that the colorful end that goes into the printer has a plastic notch on it that is in a different spot. My old one has the notch in the middle where is I need it off to the left. Can't I just shave the notch off and have it fit?

It's hard to say. Electrical equipment and parts are made for a specific reasons. Now, if you modify the power cable, it's possible that it may work. But, then again, there is also the possibility that it could do more damage than good. It will totally be your call.

Q:I need this for my class and I just need a site to start off with! Thanks

(1) Try: MSDS (wikipedia) (2) Also try: Electrical equipment in hazardous areas (wikipedia) It may depend on which country you live in. References and external links for (1) and (2) above are included.

Q:capacitor failure inductor failure thyrisitor failure i wonder if there is any solutions for these problems !!thank you in advance .

such failure high rates can be ovecome by an appropriate design choice .adequate de-rating must be considered.together with appropriate installation design which minimize hot spots and vibrations.
