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:Ever since I was a little kid I could tell when there is a T.V on in a house when I walk by. I get this feeling inside like I can sense the signal or something with my brain. When I walk closer to the T.V the feeling gets stronger. If there is a T.V left on in my house with no sound or picture playing, I am still able to sense that the T.V was left on, and pinpoint the exact room its in without even going inside. Does this happen to anyone else?

yes. it really depends on your age and hearing but the tv transmits a signal with a very very high pitched squeak when turned on which can be heard by young humans with very good hearing. I always know when the tv is on even when the screen is all black and i go to turn it off and my parents look at me like im psychic. its funny.

Q:I still don't know what course suits me. My father is suggesting me this degree. I'm just wondering what jobs could I get if I pursue this

a lot of them like;electrical engineer,powerstation manager,mine or plant engineer;works manager/engineer,resident engineer,engineering consultant

Q:I am a commercial real estate appraiser and I oftentimes need to be specific about the electrical service available within a building. I can read the service panel(s) and total the various amps volts, but I don't know what is relevant to report. For example, I recently inspected a very large industrial building and all of the service panels combined had a total of 30,000 amp, and I also noted that it had a 3-phase unit. Is that relevant to report that is was 30,000 amp, 3-phase service? Should I also report the voltage? Should it read: 30,000 amp/### volt 3-phase service. In the future, can I just read the service panel(s) and total the numbers? Just because a panel says 4000 amps, does that mean it actually has 4000, or that it can handle that many amps?I know that's allot of questions, but any help that I can get would be helpful. Thanks!

You would be better off to hire an electrician to get this info as there are a lot of variables. The voltages and phases available, the amps available, and the number of circuits in each one. Many panels you have to remove the cover to see the rating, and this is dangerous. A typical building may have thirty 225 amp 3 ph. lighting panels that are fed off of 60 amp circuits for 277 vac lighting. The service may only be 800 amps for the whole building. This is very common and meets NEC requirements. The largest bldg. where I work at the Univ. is 400k sq ft and has a 4000 amp service at the 480 volt level. This is the same as 145 amps at the 13.2 kv level. It all depends on whether or not you own the high voltage service also. An industrial bldg. could be much more.

Q:Can we use land line phone to control houshold electrical equipments. Is the techonology available. I am asking in sense how we use IVR when we call a bank, can we have someting in similar lines. For example, switing on a microwave at home before i leave office.

The answer is a qualified yes. You can connect your lights and appliances to X10-based switches and dimmers, and use the X10 Telephone Responder to control them remotely by phone. This will not allow you to turn on a microwave, because microwaves require their buttons to be pushed. But you could control lights, appliances and HVAC remotely with the right X10 receivers connected. See the links below for some phone-based controllers.

Q:A. Lockout/Tagout involves placing a physical lock and a tag on electrical equipmentB. Lockout/Tagout is necessary prior to working on electrical equipmentC. Lockout/Tagout is intended to ensure that electricity is not returned to the equipment by anyone until it is safe.D. Lockout/Tagout is to be used only in extreme cases of potential electrical hazard.

D is not true - a lock out tage is used whenever applying electricity to the circuit would result in dangerous conditions. When repair work is being done on the circuit equipment for example. Lock out tage are used for more then just electrical too.

Q:97 dodge avenger 2.5L V6 front wheel drive 4speed auto.For a little while now i felt a really light jerk type feeling in the engine during light accleration, shruged it off for needing tune-up and plan to take care of it on my next day off. Well today my speedometer droped about 40 MPH then right back to normal. Then a little bit later in the day it's doing the same but also at the same time as that problem the car will jerk like it's trying to stop itself. I then hit a hill where i had to lightly accelrate to keep speed and the jerking i shurged off started again but pretty heavy this time along with the speedometer droping. And then ontop of that the radio kept shutting itself on and off. I have no clue what's going on anymore and if these are related anyone please give me a little advice i'd be very thankful.

the engines are pretty plenty bullet data as long as you retorque the intake manifold each 5 or 6 years however the motor vehicle transmissions are rubbish. i've got been with the aid of 2 of them in a hundred and seventy,000 miles. confident I replaced the radiator placed on an after industry oil cooler yet their nonetheless basically stable for 80 or ninety thousand miles.

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:I have a piece of electrical equipment at a voltage potential of 277VAC to ground. Due to hardware problems I have an air gap of 3/8 from ground to 277VAC when it used to be one inch. Please advise if I am safe to leave it that way or should I add insulation.

That is ok with respect to any possible arc. But there may be other reasons to add insulation. Safety for example. If it's easy to add the insulation, do it. .

Q:I have a piece of electrical equipment that uses a 12v DC in that i want to replace with a battery, as it currently uses a wall charger with an AC converter. How would i go about doing this for cheap? making it myself wouldn't be out of the question, all i need is a guide. The 12v pack must also be as small as possible, as it is powering a portable device.

I would find what signal would tell the amp to go into low power mode, and force that into the high power state. One possibility is the subwoofer amps are powered only by the AC charger, in which case you could re-wire their power so they get it from the built in battery. As for actual external power, you can use a couple appropriate RC packs, or a 12V SLA type battery.
