Production description:

(1) Anti-corrosion, waterproof, low temperature rise, low noise, easy installation, no maintenance;

(2) It uses all-sealed structure. The exposed part of high and low voltage terminal is separated from surrounding by imported sealant waterproof material. It is placed in the pit when installing. And it still works safely when the pit is immersed or the transformer is submerged. It can resist flood water disaster for effectively improving the reliability of power-supply system.

(3) Low voltage switchgear uses patent outdoor light box-type protective casing. Both sides of the casing can install all-day poster board. It uses small volume, green economic LED light-emitting component

Q:I just recently bought a router that was recommended to me, Linksys WRT160N V3. I followed all the steps to connect and it works. the problem is (and i measured) i walked 34 3/16 feet away into my room and boom. no connection, and my laptop, nor my ps3 can find the router. the only thing in the way of my router and my equipment is 2 walls and a bathroom (yes a small apartment). did i buy a crappy router or is there a way to increase the range for this particular model, because i feel like i got ripped off. thanks for the help.Also i was thinking of maybe getting netgear instead, everyone else seems to think it's good i just don't have the cash. thanks for the help.: First make sure the router is sited correctly. It needs to be as high as possible and clear of obstructions. This includes furniture, electrical equipment, metalwork and people. Definitely it should be above the level of the bath, as the plumbing will be earthed, and even plastic pipes containing water have a similar effect to earthed metal pipes. If the building has metal structures in the walls these area disaster for wireless signal. But if you get it out of line from those in the direction towards your machines it may solve the problem. A very small move can often change from no signal to full signal. Do not place it too close to any wall, reflected signal can cause signal cancelling at these frequencies. The machine should also be out of line with such obstructions. Is there a hot water tank in the way? another BIG wireless killer. If this fails you could fit a longer network cable to the router from the modem, since it is a cable router. I must admit I am not too impressed with Linksys lately, but it should work well enough at that distance. Anther option is to buy a wireless repeater which just connects to power, and place it between the router and the machines, this can be sited offset (in a different direction to the bathroom) and relays the signal. This could get your signal round whatever is obstructing signal.

Q:I might be starting a job doing industrial electric, and I want to make sure I can read the blue prints good. I am recently graduated from high school and have a vo-tech background in electrical, only no blue print reading. I know how to read schematics, ladder diagrams, and residential blue prints, but how different are industrial and residential blueprints? Does anyone know a site where I can look at some industrial electric blueprints? I know when i get there they will be able to teach me how to read it, but I figured I would try to save everyone some time and see what I can figure out before I get there.: What you really need is a good book. Get a copy of Ugly's Electrical References by George V. Hart. You need to know what the symbols mean as to what they physically are. Those blue prints won't be a whole lot different in some respects from what the residential blue prints are. Ugly's will prove to be an invaluable aid to you. When you get the job, if you don't understand something, ask, they expect you to not know a lot of things. You are going in as an apprentice, so you are there to do a lot of hard work, and to learn as you go. If you are given the opportunity to go to any schools, go. If you should get the chance to go to ant schools for fiber optics, go, in fact, seek it out for yourself, even if it means night school. The pay is great, and there is always a demand for those who are trained in fiber optics installation, and repair.

Q:I'm a freshman in college in electrical engineering. I chose this major at random and so far, I hate it. I have no idea what people in my major CAN do, so when I go to job fairs, I look clueless to everyone there. The worst part is that I AM clueless. I've had companies ask me, what can you do for us? and I don't know what to tell them! Please help.: Engineering is all pretty much the same, regardless of what one builds. Consider mechanical engineering. One can either build cars or fix cars. Being able to design engines takes a master's degree at least. Fixing cars can be something done with a trade school Associates degree. This is basically the difference between electricians and electrical engineers. Obviously there are many more jobs for the electricians. There is commercial contracting or residential service or any combination of the two. Of course, you will spend your career wiring circuit breakers and very little else. To get an idea of what an actual electrical design engineer does, take apart anything electrical. All those little chips are entire circuit boards. The little metal legs are power inputs and signal inputs/outputs. Larger circuits are built up from the chips. One has to be able to read the data sheet on the chip and then be able to build a circuit around it. This is far more complicated than replacing blown fuses and explains why design engineers need masters degrees or (preferably) PHD's. If you like building things and are comitted enough to endure the many semesters of math and physics required (besides the electrical engineering itself) then design engineering is going to be both enjoyable and very profitable. Of course, becomming a technician first and then furthering one's education is another route to becomming an actual designer. Remember, besides science, economics is also an issue and education is incredibly expensive in America because people refuse to fund affordable public education with tax increases.

Q:Hi!Is there an NEC section which addresses the following kitchen design? I'm working with an apartment complex and they've designed each unit's breaker box to be located directly over the stove top burners. Something just sounds real bad here - but, perhaps I worry about things melting when water is brought to a boil or the oven is at 450 F for an hour or so and the vent for the oven is directly through a back burner. [The door for the breaker box just clears the top of the stove top.]Thank you!!: 2005 NEC section 110.26 states free space in front of electrical equipment must be at least 30 (762mm) wide. This clear space must continue from the floor to the height specified in section 110.26 (E). Doors or panels on the electrical equipment must be capable of opening at least a 90 - degree angle. Contact your local electrical inspector in the building department. They'll take care of you. Good Luck Tom A Sr. Construction Project Manager Albion, MI

Q:i replaced my home theater system thinking it was busted but when i recieved my new one it still had the same buzzing sound i noticed the buzz is in the bedroom too: It sounds like somewhere in your electrical you either have a bad ground, or there is a florescent lamp or some other piece of electrical equipment causing the noise. Surge protectors will only help with an electrical surge, a power conditioned is what is used to remove noise from electrical lines. Check the different electrical equipment in the house by turning things off or unplugging them and check if the noise goes away, if not it could be in your electrical system or some kind of outside interference. If you still issues purchase a surgex power conditioner and that should take care of your issue.

Q:I'm a fresh grad licensed electrical engineer. Which field in electrical engineering job should i enter? for example, in construction, in manufacturing of electrical equipments in substations and the like, in distribution utilities/gencos.: distribution utilities/gencos

Q:I am living in a state where there is lots of Electricity cut off in other words the Loadshedding.When I listen to radio on short wave and medium wave during no electricity ON in our town, it plays well and clear. But when electricity comes its totally inaudible because of too much noise like srrrrrrr, shrrrrrrr,trrrrrrrr. Means I have to turn my radio off. My question is what thing does this cause??: It is interference produced by electrical equipment such as motors, TVs, transformers, computers and fluorescent lamps. I guess your radio is battery operated. If you take it a mile or so outside the town, you will find you get good reception with no noises. I get this at home too. I find if I want to listen to short wave, I need to turn everything off, including fridge, TV and computer. You could try turning everything off in your house and see if it helps.

Q:i know that megger is used in marine.but how its been used and please give me other megger application in detailedthanks for answer: In electrical testing we megger equipment. A ac voltage 600 volts is induced one a piece of electrical equipment like a transformer and the impedance is measured. The megger measured AC resistance/impedance vs normal dc resistance that volt meter measure. The higher voltage gave a more accurate measure of impedance. Equipment with defective insulation, would have a lower impedance.

Q:if you've heard of the wilhelm scream, is there an equivalent for an electricity crackling sound?I've heard it in Star Wars, many cartoons, probably Spider-man (it's like imagine when some big electrical equipment goes wrong and starts producing sparks, or when you have some space laser gun that stuns people).Any idea?: I think it comes from Frankenstein, with all that electrical equipment they used

Q:A.neutralB.groundC.short circuitD.load: Voltage in the US is 110-120 volts while in other countries it is 220-240 volts. if you have a 110-120 volt appliance, you need a step-up transformer (110 to 220)before you could use it in a 220 volt power supply.
