Q: I am getting my BSEE in a couple months and i'm curious as to what to expect or ask for. I am graduating from a good engineering school (UM Ann Arbor): Entry Level Electrical Engineer Salary

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 :): high frequency machine, bio face lift machine, ultrasound machine, beauty studio, brushing unit, galvanic machine are few of the machines used

Q: during line to ground fault, is there really a current that will flow in the ground, how will the grounding rod help if there is no connection back to the source? please explain how grounding aids tripping of C.B's: 1. The purpose of the grounding rod is to give electrical equipment and its housings a grounded reference point. Without this the voltages of these might go wandering off to indeterminate levels causing (in extreme cases) arcs to jump on to passers by or door handles to provide major or minor shocks. If there is a fault in equipment which causes an higher voltage part to come into contact with a grounded part then a current may flow into the grounding rod. The return path of this current is through the ground (earth) via another grounded point (e.g of the local supply transformer's star point) and thus into the transformer at its low voltage winding end. If the supply has no such grounding point (this would, by the way, be most odd but it is physically feasible) then there would be no fault current flow but the grounding would still provide a degree of security from high voltages.

Q: has to do with electrical control: NFPA 70 has to do with safe installation of electrical wiring and equipment. The National Electrical Code (NEC), or NFPA 70, is a United States standard for the safe installation of electrical wiring and equipment. It is part of the National Fire Codes series published by the National Fire Protection Association (NFPA). National Electrical Code and NEC are registered trademarks of the NFPA. While the NEC is not itself a U.S. law, NEC use is commonly mandated by state or local law, as well as in many jurisdictions outside of the United States. The NEC codifies the requirements for safe electrical installations into a single, standardized source. The authority having jurisdiction inspects for compliance with these minimum standards.

Q: I have just recently started getting electric shocks at random times when working with my tank. The first time it happened i was wearing a rubber glove (which i thought would block electricity in the first place) i put my hand in the sump and it tore through the glove and shocked my whole arm. The next day i was using the net in the tank itself and got a big shock, then the same thing happend to my brother, my girlfriend and my friend all at different random times. It feels like one of those trick handshake or trick lighters that people have but it hurts way more. Basically the shock runs through my arm and into my chest, leaving my arm numb.I have a 72 gallon bowfront saltwater set up with live rock, about 15 fish, the whole deal. I have the coralife 260 watt compact fluorescent light hood with moon lights attatched with plastic legs on top of the aquarium over the glass canopy. I have an 850 gph pump in the sump, a 300 watt heater in the pump and a protein skimmer in the sump.: You might want to contact a certified electrician by phone. This could be very unsafe.

Q: I know that it would destroy active electrical equipment but if the device had no electricity going through it at the time could it be affected?: The answer is yes. unless the device is shielded and grounded to remove the electrical field that is now around it, the delicate electronics in a chip will be burnt up just because of the presence of the field itself. items with much more tolerant wiring, such as bulbs and tubes, are a little better equipped to survive. The funny thing about a Humvee is that it has a diesel engine, which is not effected by an emp pulse. that's why the US military went to diesel powered vehicles in the 1980sbecause they don't get creamed from EMP.

Q: i am going to ship my furniture including my electronics( refrigerator, recorder, laptop, dishwasher, drier, etc) i want to now if the voltage in USA is 240v as in Dubai or 110v and i case of difference i want your advice i`ll ship them or not: Kaed59, The usual problems of shipping GCC electonic and electrical equipment to the USA (NOT applicable to Saudi Arabia) is that the main power supply in USA is 110VAC as compared to the UAE - which is predominantly 220VAC (so you will be needing lots of transformer or a big transformer with a bigger wattage rating. But the biggest problem is actually the frequency (Hz). The US utilize a 60Hz frequency as opposed to the UAE, Bahrain, Oman, Qatar and Kuwait's 50Hz frequency (KSA use 60Hz). Hence, you will find in SOME of the electrical appliances and equipment as rated 90-230VAC 50-60Hz. These are universal appliances which can be used both in European (50Hz) and American (60Hz) power supply. Unless specified by the manufacturer to operate on either 50 or 60 Hz, appliances may not operate efficiently or even safely if used on other than the intended supply frequency. I would suggest you check before shipping them and dispose locally before you shipp to US. Good luck and have a safe journey !!!

Q: i want to know about latest technical electrical machine used in ship's during sailing.Eigther it may be electricity generator or any other equipment.: the newest state of the rt electrical systems on large ships are 'podded propulsion; instead of turbines turning propellor shafts, generators supply electricity to motors that are placed in pods outside the ship, under the hull which turn the propellors.go look up 'Queen Mary 2' on the web for details.

Q: I have a sprinter van. Need to be able to power 4300 watts worth of electrical equipment. Like power conversion alternator etc What would i need to do. the equipment. cost etc.: Are you trying to power 120 Volt or 12 Volt electrical equipment? Either way you're looking at nearly 400 amps of additional load on the vehicle and that's a waaaay lot. If your equipment is 120 volt it would be much easier and cheaper to install a generator. Some generators even have regulated outputs that are very precise and surge-protected for sensitive equipment. If your equipment is 12 volt (such as a rack of amplifiers) then you're looking at adding a couple (or more) alternators and may need custom bracketry and fanbelts to drive them. I was at a car stereo competition years ago and there were vehicles with up to 6 alternators. The problem you will find is alternators are rated at their maximum output, not what they put out at idle. Even a 230 amp alternator may put out less than 100 amps at idle. Look for alternators built specifically for use while idling if this is your situation - either industrial vehicles or special alternators designed for stereo competition with high output at low rpms. If I was you I would research what types of industrial uses the Sprinter has been modified for and some of them may have already solved the very problem you're having.

Q: I have a 1992 F-150 with a 5.0 302 in it. Last week she started going haywire. My battery wasn't holding a charge, my spedometer was bouncing up and down and my mileage read was coming in and out. I had the diagnostics test done from Auto-Zone that tested your battery, alternator, and starter. They said that my alternator had low power output but everything else was fine. My dad (he's a mechanic) said I had to replace my voltage connectors on my alternator. We did that and she acted fine for about a week. Battery was holding a charge, no problems at all. A couple days ago, my battery light popped on and the battery is not holding a charge AT ALL. I constantly have to charge it. Any ideas on what the new issue could be?: change the alternator and make sure the belt is good and tight ! your voltage regulator is inside the alternator and it,s acting up !
