- 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: Do they design circets for the electricity? If not, what do they design?
- There are many different areas of specialization in electrical engineering.
- 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: .and what does it entail?
- I woulds say easily electric powered engineering, counting on the concentration. by way of some distance the biggest utility of nanotechnology is for semiconductors. I did a level in electric powered engineering specializing in VLSI (in reality microchip layout and fabrication). electric powered engineers in this sub-discipline use widely used and quantum physics to layout small scale structures like circuits, MEMS (micro-electo-mechanical structures), and micro-fluidics contraptions. electric powered engineers greater concentrated in issues like E+M fields and capacity distribution have not something to do with nano. Mechanical engineers won't study quantum physics, it is needed for nano-scale contraptions. no rely what, nano-scale fabrication is bypass-disciplinary requiring electric powered, chemical, fabric, and mechanical engineers as properly as scientists and technicians.
- Q: Greetings, I've noticed that my electrical power company is constantly sending me a reports on how much electricity I am using with respect to my neighbors, kind of trying to get me to use less energy. I figured that if a company is in the business of selling something, it might as well encourage you to use more than you really need.Why is my utility encouraging me to use less electricity? Is it because they feel there's going to be a backlash against the industry once the word gets out that utilities are big drivers of global warming, and they are trying to do damage control ahead of time.Remember, we live in a capitalistic society where maximizing profit is key to keeping investors happy. I can understand the water company asking me to consume less water, as water is a scarce resource. Coalwe have lots and lots of it. Enough to burn for a few hundred years.
- You may need to update your electrical equipment for more efficiency.
- Q: hey yahoos , i just graduated this december on the 22nd with a degree in Electrical and Computer engineering . Apart from the fact that i graduated with a decent gpa ( not that great ) i have no idea why i chose that major or what kind of a job i should be looking for . I didn't have an internship , because of the pressure i was getting from my family which cooked my brain , and i'd rather Not do anything due to pressure than do Anything on my own. I have lost 75% of my motivation already and currently my only motivation is to buy some nice Gadgets, other than that , i don't know :( . , i was wondering if anyone could just advice me anything as if to what kind of a job should i be looking for in this field. What does it even mean by the term junior engineer. , Does anyone know if it's any good to learn 80% of electrical stuff and 20% of computer stuff. Is there a job market for that ? i am looking for a job in new york city itself . i don't have any more characters .:-(
- Electrical Engineering is the main degree people get. With that you can specilize in computer and microprocessors design, or antennas and microwave design, or power. So you will be fine.
- 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: I know that means i'll choose my job at basic but does it mean that I could get a job I don't want? I really want to do Biomedical Equipment Tech.
- I believe it means you will get a job in the Electrical Aptitude area. Sometimes an enlistee without a guaranteed job gets other than their first choice. The tech training for that career field is 10 months long. 4A231 Biomedical Equipment Sheppard AFB, TX Sometimes the dates do not match up for the transition from BMT to technical training. When I enlisted Open General back in 1975 I was originally slated to be an Altitude Chamber Specialist (now Aerospace Physiology 4M031) but missed the training start date and instead was sent to Aeromedical Specialist (now Aerospace Medical Service 4N031) school. It was then part of the School of Aerospace Medicine at Brooks AFB in San Antonio. I spent about a month in casual at Lackland doing menial tasks during the day awaiting the start of my tech training. I was fortunate as the job I got involved working in the Flight Surgeon's Office. It included patient care, physical exams, crash ambulance crew duties and much more. You can get a job you do not want. Or you can get fortunate like I did.Best of luck to you.
- Q: I need some opinions on why do we recycle, computers, tv, cellphones, etc.I know it saves the environment because if we throw it away, it would just end up in landfills but is there anymore reasons?
- Why Should We Recycle Electronics
- Q: Context:Unrated electrical equipment in the dust handling equipment and area could act as an ignition source, which would result in a fire or an explosion for the dust handling equipment or rooms.
- It refers to both the equipment and the area.
