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 have a dental Lab in Europe an want to move it to the States, maybe. Some of the equipment rates as high as 4kw, and the the total maximum draw is 15 kw for the whole lab. Can I wire a secondary breaker box in a building in the United States that is all 220?
- Sell it off in Europe and start off with new equipment in the States. All European electrical appliances operate on 50 Hz/cycles when American appliances use 60 Hz. It's not feasible to adapt the change. There is 220V service available here but it's all 60Hz. EDIT: If the equipment is rated for 50/60 Hz you can use it here, you'll have to bring in an electrician to provide the power for it that can produce a stable/clean 220V. Most of the time higher voltage equipment will be rated to perform between 208-230V although having a single-phase power supply for 220V is feasible provided your equipment is indeed single phase. I'd think that what you have for a dental lab wouldn't require three phase power, best to consult with a master electrician before you commit to shipping your stuff stateside to be sure. Good luck.
- Q: For instance, could you use normal 14/2 building wire normally used in houses for 115 volt AC lights and outlets and run DC through it provided that the voltage and current does not exceed 120 volts and 15 amps?Could you use normal in-wall light switches in the same way as long as the DC volts and amps does not exceed the AC rating?
- No, this is not safe as far as switches are concerned. When you open a switch (turn a light or appliance off), a tiny spark is generated which erodes the contacts slightly. Over a period of many actuations of the switch, it will degrade to the point of becoming dangerous or non-functional. Every 0.02 of a second (50Hz mains) or 0.017 of a second (60Hz mains), the voltage in an AC circuit is instantaneously zero. The tiny spark generated cannot last longer than this at most, and some of the time even less. Therefore the erosion of the switch contact is small and the switch last for many years. In a DC circuit, the spark lasts as long as it naturally would. This may be a lot longer than 0.017 sec and may erode the switch contact a great deal faster than it would for AC. This causes a defective, maybe dangerous, switch much sooner. The longer duration spark itself is a safety hazard from the point of view of fire safety. A DC switch for 115V will be a much more heftily engineered than an AC switch. A standard AC switch must not be used for DC.
- Q: I have heard that an electrical ark can kill you so I would like to know what circumstances creares this condition.
- *An electric arc is an electrical breakdown of a gas which produces an ongoing plasma discharge, resulting from a current flowing through normally nonconductive media such as air. A synonym is arc discharge. Undesired or unintended electric arcing can have detrimental effects on electric power transmission and distribution systems and electronic equipment. Devices which may cause arcing include switches, circuit breakers, relay contacts, fuses and poor cable terminations. When an inductive circuit is switched off the current cannot instantaneously jump to zero; a transient arc will be formed across the separating contacts. Switching devices susceptible to arcing are normally designed to contain and extinguish an arc, and snubber circuits can supply a path for transient currents, preventing arcing. If a circuit has enough current and voltage to sustain an arc formed outside of a switching device, the arc can cause damage to equipment such as melting of conductors, destruction of insulation, and fire. An arc flash describes an explosive electrical event that presents a hazard to people and equipment. *An arc-fault occurs when loose or corroded connections make intermittent contact and causes sparking or arcing between the connections. This translates into heat, which will break down the insulation of the wire and can be the trigger for an electrical fire. Unlike a short circuit, that is a hot wire coming into contact with a ground or neutral wire, arcing may not trip the circuit breaker. If you’ve ever heard a switch buzzing, hissing, or popping, you’ll know what I’m talking about. In order to protect your home, an arc-fault circuit interrupter can be used to detect just such a problem.
- Q: Have a neighbor that is selling his van to an 80 yr old man. The van has serious electrical issues that go off and on. Just so happens it was working right when the buyer drove it. But almost everything in the dash goes on and off. Mostly it stays off. Is it legal for the seller to not be honest?
- caveate emperitorlet the buyer beware. it not illegal to non disclose faults, but it is a dick thing to do.
- Q: I don't understand how oil and gas industry has anything to do with electrical engineering jobs??Am I not seeing this because currently I am working as a electronics engineer ? This is how I am thinking about this - Oil and gas industry , digs up oil , provides it to our cars and trucks so they can run. Now I don't understand how or where Electrical engineers come into play into this ?? Please make me understand. I want to know.P.s: I am an entry level electronics engineer, with a degree in Electrical engineering , Currently I am located in Houston, texas.
- This website will show you jobs in your discipline in the oil and gas industry. Take a good look at the descriptions to find out what the work could involve, and follow a trail on the internet to see where you could use your skills in your local area. You will need to think about travel at some point though, in this industry.
- Q: I am an undergraduate in Electrical Engineering and I want to design and work with generators. What institutions research electrical generators? What companies design/build electrical generators? What is the difference between electric drive systems and generators? are they the same thing?Much thanks.
- you may desire to lie down so a recumbent device sounds in simple terms right to me ,then you would desire to be waiting to push against something so shoulder pads could look appropriate use gears till tou be responsive to which ratio is nice then use it to layout a belt device(toothed) direct onto generator,then something to study or watch jointly as you artwork of your pent up frustrations(scientific care to boot!!).you may prefer something to checklist your efforts on your guy or woman delight.desire thats adequate for now
- Q: I'm considering buying an assortment of electrical equipment whilst on holiday in the US. Will they work in UK? Thanks in advance1) TV. Gut feeling is that the digi tuner (NTSC/PAL) will be different and its going to be a nightmare with the actual power.2) Nintendo DS. I think i will be ok on this one as games are not region enabled. Charger maybe an interesting one.3) Cable modem. No idea :) but i need a cable modem for home.4) is there such a thing as a DAB radio in the US? I saw some really strange radio setups but no DAB.5) Digital Video Camera. Makes to avoid for the change to UK?Thanks again for reading and taking time to reply.
- I would not buy ANYTHING with a video output. In the US most video-related equipment supports only NTSC. This takes care of TV, DS, and Video camera. I doubt the cable modem will also work. US has HD radio, which will not work either.
- 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 suspect my house electrical ground isn't working and had suffered equipment loss due to loss thunder strike.
- The last three electric utility companies we've done business with offer whole-house lightning protection, with a guarantee. Not free, but the good stuff. I've not used it, having just the usual consumer electronics, not like a home-office server system, etc. Out here in the plains, we have some of the biggest thunder storms in the country, too. If it's a Big one, I'd more likely physically unplug my best stuff, take a bit to get ready to go to basement shelter if a tornado warning is broadcast, and call anybody that's away from home to make sure they stay alert. Next door, the neighbor's house was hit by lightning three times over ten years, finally apparently stopped by tree-pruning and complete removal of one big tree that, at about 120ft in height, had acted as a lightening rod. Just an anecdote.
- Q: EMP Electromagnetic Pulse
- The EMP has the capacity to damage electrical equipment regardless of the source powering the electrical equipment, especially now that power generation devices depend heavily on sensitive microelectronics.
