- Q: if you was recently shocked twice (bad enough that it went all the way from your fingers down to your toes) and then you had a headache and an occasional shooting pain through your arm would there be any reason for concern or is that just normal?and also, would there be any chance, that when you're touching water and metal in a very cold atmosphere (35degrees or so) that static electricity could cause that bad of a shock or would it definetly have to be some certain of electrical wiring problem?
- I am not sure where you received the shock. Was it static discharge or was is from wiring? Electrical discharge is always a grounding problem. When you get shocked, the electricity has found you as a shortest path to ground. In wiring, this is typically caused by exposed wiring due to stripped or worn insulation. This can also be caused by loose or bad connections where the phase wire is close to or touching the ground wire. If it is static, I have found that dry, cold weather substantially increases your chance of getting a severe static shock. Personally, I seem to be more subceptible to static shock than other people. I have gotten painful shocks from anything from car doors to blades of grass to running tap water, the kind of shock you can hear from another room. Lightning is actually a magnified form of static shock, whereas shock from wiring carries 60Hz of frequency and has a different effect on your body. If you received a shock from wiring and it went all the way through your body, the electrical source essentially pulsed through your body 120 times per second. This can actually cause your heart to try to beat 120 times, leading to cardiac arrest. Obviously, this did not happen to you, but there can be all kinds of strange physiological phenonema that can occur, such as the headaches you mentioned. I would not be too worried as these will eventually probably go away. I worked with a woman who once got a severe electrical shock from a piece of equipment that blew her away from a piece of machinery, and she had her period as a result. She recovered.
- Q: I know you need fuses for cars, electrical equipments, etc. I don't get what they are really used for?
- If there occurs a short circuit or an overload beyond the current rating of the fuse, the thing melts inside, breaking the contact, stopping current flow, and sending someone off in search of a new fuse rather than repairing the situation which blew out the last one. Nothing in the fuse breaks, it melts. A fuse is not a mechanical circuit breaker, which is an actual switch actuated either magnetically (in AC circuits) or a bimetallic strip which has the current going through it and gets hot enough on excessive current that it self-bends and breaks the connection temporarily, and can be reset. Once a fuse blows, it's over for that fuse.
- Q: Before anyone blindly answers this, I'd like to first request that only people in the power transmission industry answer, as they are the only ones likely to know.I have a customer who is asking to mount several very large pieces of electrical equipment 15 feet in the air, mounted to a large structure. All of these equipment pieces are 5000 or more pounds and pad-mount by design. I am questioning this request on the basis of legality. Basically, I am curious to know, is there anything in the NEC that says mounting pad-mount equipment overhead is illegal? If so, I could really use a hint as to what section of the NEC code.
- I don't believe that there is anything in the NEC that addresses this. Obviously, installing anything on a structure presents challenges that require the attention of a qualified structural engineer. And depending on the location, you could be facing some additional concerns. You would need to check on seismic activity in the area, and since 'pad mount' equipment has a broad profile, wind-loading could be more challenging if you have a wind-force specification to meet. The other issue you would need to consider is whether installation on a structure presents any particular safety concerns. Without knowing any more, my inclination would be to think that you might want to provide an enclosure around the structure to prevent civilians (rmeaning 'teenagers and drunk college students) from climbing it. Just out of curiosity - why does your client want this? We know that the client is always right - even when he insists to stupid things. I trust there is a good reason for asking for something that is bound to increase installation cost by probably 100%.
- 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).
- Light should be lights, since I'm sure there are more than one. Run around is somewhat confusing. Because it sounds like the phrasal verb to run around, as in running around the house for example. Maybe say in the parentheses (except those that must remain on continuously) .
- Q: a small fire that is at the outlet
- Unplug it from a distance and then throw tons of baking soda or flour on it until the fire is smothered.
- Q: i need what to do in a bad thunderstorm
- definite. The turbulence interior a thunderstorm could nicely be very severe. in certainty, as a thunder cloud (cumulonimbus (cb)) is turning out to be, the air interior is being pushed up and large velocity and carried with it water particules. To fly with the aid of a cb is risky for the reason which you will positively stumble upon severe icing situations. Icing could reason subjects with the engines, besides as with the raise produced via and the soundness of the plane. it could additionally block static and pitot vents (required for various contraptions interior the airplane) whilst a thunderstorm is energetic, the water is in certainty too heavy and starts falling down interior the path of the cloud as hail or rain, yet this additionally reasons downdrafts (severe velocity wind transferring downwards) alongside with the updrafts this creates severe turbulence and in very great thunderstorms the rigidity from the downdrafts must be sufficient to rigidity an plane downwards in the direction of terrain. At airfields, physique of techniques and landings are no longer oftentimes allowed whilst an energetic thunderstorm is interior of sight because of this and likewise the prospect of windshear. With regards lightening - it is not the main deadly part of a thunderstorm in any respect. There are static wicks to disperse the electrical powered energy. in spite of the undeniable fact that, a marvelous flash can quickly degrade a pilots ingenious and prescient which isn't so risk-free. we've climate radar and could see the place they're and stay clear of them yet around the equator, multicell thunderstorms can selection for 100s of miles wherein case the very turbulent centres could be prevented yet patches which teach as lighter factors (amber on the climate radar) ought to nonetheless be flown with the aid of.
- Q: I'm a student looking for things that are involved in R and D aside from Scopes, Logic and Spectrum analyzers, Signal and Waveform generators and VNAs. Things outside of what Tektronix, Agilent and Lecroy would be involved with.
- I grew up working from a block diagram . It is good to have some good programs to do the work for U. Learn the test equipment well as some times u can be tricked that there is a problem when there is not. Communications was good to me.
- Q: If a landlord is renting out an old home and the tenant suffers regular damage to his or her electrical equipment, would the landlord be responsible for having the building wiring updated so that such damage does not continue to occur on a regular basis? What if the cost of such repairs far exceeds the rent that the tenant would be paying? Would the tenant be legally able to break a lease without paying fines in this type of situation?
- As long as the wiring was at code when the house was built he does not have to change it. BTW, it would cost about a years rent, you are talking about a major renovation. It is normally only done during other major renovations, not by itself. This does not break your lease. Haven't you ever heard of surge suppressors? Buy yourself some.
- Q: I plan to major in electrical engineering. I wanted to know if the stuff I learn there will allow me to do things like fix machines and stuff.I picked this major because I wanted something I can use at home
- definitly after four years of B.E. programe in ELECTRICAL ENGINEERING you will be able to design circuits and erect electric connections at your home. it depends fully on how you study this subject you need to correlate with practical scenario you must try to experiment things at home. If you pursue this course with full aptitute and involvement i am sure you will achieve wat you wanted to use at home and also for the nation. ALL THE BEST ENGINEER!
- Q: I know water can damage electrical equipment, but why can water do this? I'm sure it has to do something with electricity and water. I seek an in-depth answer that will leave me with no doubts, or further questions, if possible.
- Water is a polar molecule and in nature contain impurities which enhance it's conductive ability. So water become a conductor when introduced to electronic devices and electricity follows the path of least resistance, which is no longer the desired circuit. So with the electricity being conducted into places that are not desired it often causes components to fail by overloading them with power. Electrical equipment that gets wet while not connected to power often can be used provided it is allowed to dry out completely before power is applied. For example I have been know to put keyboards in the dishwasher and as long as I wait before I used them afterwards. But pour a cup of coffee into the ketbouard while in use and generally it is toast.
