- 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: Hey, I need to find out different electrical equipment used in a Beauty Salon and I can hardly think of anything! I can only think of wax pots and tanning beds :S Any other suggestions? Actual answers only please, don't bother writing Do your own homework or whatever because I really can't be bothered with people like that. Like I said I have TRYED and I cannot think of alot. Thankyou :)
- I have an easy fool-proof way to figure this out. Look on OKorder. You can see what people are asking and paying for such fixtures and equipment. if you don't see anything for sale, check the completed items. You will be surprised at the information you can find. No doubt you will figure out the fair market value of the items.
- Q: Also how do we know our brain has electrical pulses. How do u prove it
- the electrical powered currents working by way of our bodies and brains are the consequence of chemical reactions. and of direction, a number of the chemical compounds are leftover after our dying, besides, the electrical powered currents could have been lost as warmth maximum possibly. So i assume you may desire to call the the rest power a 'ghost' yet then you certainly could desire to easily as truthfully call a muffin a ghost, because of the fact it too is made up of chemical compounds and could have been heated via an electric powered oven. in certainty, each little thing could be a ghost if so (radio waves, plastic chairs, yogurt, concrete blocks, t-shirts and so on) each little thing is made up of chemical compounds and includes electric powered power.
- Q: 715442443
- If you like physics, I would look into mechanical.
- Q: I just replaced a light fixture in an apartment complex.I discovered that the bonehead that did the install did not run an equiptment ground when he installed the entire circuit that the light is ran off of (dumb a**!!!!!!!!)Does anyone know if it would be up to code if I where to just drive an 8 ft. ground rod and ground the fixture/entire circuit off of the rod?I have looked everywhere.Cannot find anything in code books.If someone knows where this is in NEC, please include the location.Anybody have any input?
- As mentioned the box may be grounded and you cannot see it. If it is not then you must ground it. There is code that will tell you the gauge of the wire that you must use for each circuit. The new code indicates that you do not use a ground rod, but a ground plate. That plate must be buried deep enough that it is in damp soil or it will not work. I am not familiar with the plates, but with the ground rods you need to have more than one and they have to be separated. I have attached a link to the city of Concord code.
- Q: 2)Please do include the details as to why does spark devlop wn connection at one end is loose. 3)How the +ve electrode retains itz polarity though it accepts the electrons continuously, in a closed circuit.
- i could agree that a window unit would be your maximum expedient answer. Evaporative coolers are available as window units, are greater fee-effective to run and supply adequate cooling in case you reside in a dry climate (until this is one hundred and five). Any companion and young infants equipment will perform with no floor, yet to function good, you would be wanting it grounded. An air conditioner attracts a lot greater modern-day than a lamp, working example, so the threat of electrocution is larger. A grounded adaptor could paintings in case you're confident to connect it good. by using ways, if air con replaced into between the constructive properties of the abode once you rented, you in all probability have ability of recourse with the owner if he (or she) chooses to be obstinate. good success.
- Q: I am just a few classes away from getting my Associates in Electrical Engineering. I currently have a Diploma in Industrial Electricity and have been working in industrial maintenance for 12 yrs. and am currently an electrical technician (10 yrs. multi-skilled and the last 2 yrs. strictly electrical due to a job change). I have returned to school to get my AAS in EE, so I would really like to know what possibilities I could expect.
- You can get a job as an electronic engineering technicians. You help design, develop, test, and manufacture electrical and electronic equipment such as communication equipment, medical monitoring devices, navigational equipment, and computers. You may work in product evaluation and testing, using measuring and diagnostic devices to adjust, test, and repair equipment. Median annual wages of wage and salary electrical and electronic engineering technicians were $53,240 in May 2008. The middle 50 percent earned between $41,550 and $64,120. The lowest 10 percent earned less than $32,490, and the highest 10 percent earned more than $78,560. Median annual earnings in the industries employing the largest numbers of electrical and electronic engineering technicians were:
- Q: definition
- *Many electrical installations have a relatively high earth impedance. This may be due to the use of a local earth rod (TT systems), or to dry local ground conditions. These installations are dangerous and a safety risk if a live to earth fault current flows. Because earth impedance is high, 1. not enough current exists to trip a fuse or circuit breaker, so the condition persists uncleared indefinitely 2. the high impedance earth cannot keep the voltage of all exposed metal to a safe voltage, all such metalwork may rise to close to live conductor voltage. These dangers can be drastically reduced by the use of an ELCB or Residual-current device (RCD). The ELCB makes such installations much safer by cutting the power if these dangerous conditions occur. This approach to electrical safety is called EEBAD. In Britain EEBAD domestic installations became standard in the 1950s. In non-technical terms if a person touches something, typically a metal part on faulty electrical equipment, which is at a significant voltage relative to the earth, electrical current will flow through him/her to the earth. The current that flows is too small to trip an electrical fuse which could disconnect the electricity supply, but can be enough to kill. An ELCB detects even a small current to earth (Earth Leakage) and disconnects the equipment (Circuit Breaker). Go through the source links. Also read and seach for residual current device.
