Q:can i sell magnetic contactor transformer 24vand where ?

With an accurate description and a couple of good pictures, you can sell just about anything on OKorder. Don

Q:I am an electrical engineering graduate with very little knowledge of business studiesHowever, I will be beginning my career as a procurement engineer in October.In your own words, what is this?and what duties might it involve?Warm regards,de Róiste BSc

You will probably be responsible for specifying electrical equipment required for purchase for various projects, for recommending various vendors to obtain bids from, for putting request for equipment bid packages together, and then for making recommendations for which vendor(s) to buy from. Seems like you should have asked your employer what your duties would be.

Q:Been using mercury Monterrey (2004) for my mobile DJ for about 2 years and a am working on changing it because i don't think the van can handle the amount of equipment i have right now. Advice Needed please- Should i still go for Van or Truck - please explain why

Van. Better security and if you get caught in the rain, better protection of the electrical equipment.

Q:I know that B is flammable liquid and C is electrical equipment. thanks.

Solid combustibles, like wood and paper.

Q:If it is, why?

we use this concept in order to bypass the fault currents, as we know that fault currents are of high frequency. and also the equivalent circuit of the earth is the parallel combination of the resistor and capacitor,also capacitor acts as short circuit(i.e of least impedance). Xc1/(2*pie*frequency*capacitance)

Q:I have had a problem for the last 15 years or so where I seem to interfere with electrical equipment. For example, I can't wear watches, I burn out tradition incandescent light bulbs like most people change their drawers, I get all kind of feed back from the intercom system in the hospital where I work (in the form of staticthe speakers actually go off as I walk down the hall.it's kind of a joke to my co-workers - some of who have decided I'm possessed - LOL), computers freeze up on me frequently and I completely fried our last home pc.any others out there with similar problems. I assume it has something to do with electromagnetic fields.but not positive about thatany ideas?

The only natural explanation is that you have had some bad luck with electronics. On top of that you are probably exercising a little confirmation bias when you remember the things that went wrong but don't take note of things that don't go wrong. If you were electronically jinxed then *everything* you touch would fizzle, not just a few things. My mother goes through watches all the time. It's because she buys cheap watches. My cell phone causes speaker buzzing. My old Sprint phone didn't, but my ATT iPhone does. It can be quite loud and the range is enough that it causes my coworkers' (phone) speakers to buzz as well. The human body does emit an electrical field, but it is so minute as to have little or no effect on things around it. The field diminishes to such a rapid degree that if you could measure 10 units (whatever those units are) one inch away from your body you would only be able to measure 1 unit two inches away from your body. So it's not magnetic or electric. It's probably just bad luck, confirmation bias, some other contributing factor you're unaware of and, honestly, possibly a bit of user error too. If you have serious concerns you need to document this. Get a doctor or other impartial party involved. Measure this effect and try to reproduce it. Unless you get hard data that points only to you as the cause you are not going to be taken seriously.

Q:i dont understand this, every surge protector claims to protect phone lines from surges but why?

Because DLS and phone lines operate on voltages and currents and are susceptible to lags/spikes. GL

Q:if my electrical equipment has a fuse; does that not mean it's protected?is it just the power grid that goes down?

it induces overloads that defeat the ability of the equipment to deal with excess voltage. heat is generated, and things burn up , or melt. the 1859 solar flare actually shorted out heavy copper telegraph cables.

Q:I suspect my house electrical ground isn't working and had suffered equipment loss due to loss thunder strike.

If the Lightning is hitting your house then you need to call in a profesional for insurance reasons. If it is hitting elsewhere and causing damage through you electrical lines or through your grounding system then you need to look into surge suppresion for your system.

Q:I received a piece of electrical equipment from China which has a power lead with it. It originally had a 2-pin plug which I have stripped to rewire into a 3-pin UK plug but the wires are blue, black and brown! I am confused now as I thought either blue/black could be neutral or black/brown could be live. Didn't expect blue, black and brown in same wire.

Connect to Live (brown wire) and Neutral (blue wire). Leave the Earth pin in place but unconnected. Make sure that the plug has a 5 Amp fuse in it (these usually have a blue coloured body, 13A fuses are brown). If the wires are not blue and brown then you must make sure that the voltage is correct. UK mains is nominally 230 Volts, the same as the rest of Europe. Blue and brown are the standard European colours for mains wiring. If the razor is non-European then it may be designed for 110 Volts and will be destroyed when you plug it in. If this razor is an old British one it may have red and black wires. These colours have not been used for appliances since about 1968 and so the device will be very old and may be unsafe.
