What are some words to describe an electrician?
Electricians are humans. They are not necessarily precise. They should be knowledgeable, considerate, careful, and aware. Sometimes they are stupid, injured, careless or drunken. Electricians should be licensed around here though some are not. Some electricians are shocked. I know of several electricians who are disabled. They lost the use of an arm through electrical shock. Some are dead. That's how a friend of mine got a promotion. The guy over him died. Need any more words? They are human just like you and me. Take your pick.
R&P: Hey Nirvana 'fans', let's see how knowledgeable you REALLY are (plus R&P Hall of Fame results!)!?
1. Krist (or Chris as he once was called) Novoselic, Dave Grohl, some former members include Chad Channing, Aaron Burckhard, Dale Crover, Dan Peters, Pat Smear, and so on. 2. Their first drummer was Aaron Burckhard, though they were not called Nirvana at the time, the first official drummer under the name "Nirvana" was Chad Channing (though Dale Crover did some studio work and possibly some live things occasionally during 1988). 3. Raw Power- The Stooges. 4. Kurt and Krist were in a Credence Clearwater Revival cover band for a short amount of time. 5. The Vaselines, the members being Eugene Kelly and Frances McKee 6. Krist is a local politician in south-western Washington state, he also writes a great blog and might be making a solo album..Dave is in Foo Fighters, and occasionally will do guest drumming for bands, oh yeah, and he's a father (of two now!). 7. Kurt was the shortest, he was around 5'8", Krist was the tallest, around 6'8". 8. Drain You, Sappy, Pennyroyal Tea, Serve the Servants. 9. In Utero, 'nuff said. 10. With the Lights Out. 11. Pixes, The Beatles, Black Sabbath, The Stooges, The Melvins, Mudhoney, Aerosmith, Led Zeppelin, The Vaselines, Black Flag, Meat Puppets, Sonic Youth, etc.. 12. Krist! He was actually born to Croatian and Bosnian immigrants, I'm 1/4 Serbo Croatian myself... :P 13. Sappy, You Know You're Right, Serve the Servants, Smells Like Teen Spirit, Pennyroyal Tea, FFWHROS, Lounge Act, Something in the Way, All Apologies, Aero-Zeppelin 14. An electrician. 15. Courtney Love! (rock on, CL!) 16. Hole!!! =D 17. L7, Soundgarden, Screaming Trees, Pearl Jam, Alice in Chains, Mother Love Bone, Mudhoney, Green River, Tad. 18. Charles R. Cross, but he got a fair amount of stuff about his childhood wrong, supposedly. 19. I don't know... its a long long story, I think, they are just a magnet for poseurs, and they have been since Smells Like Teen Spirit came out. 20. HOLE, Led Zeppelin, Pixies, The Smashing Pumpkins, Joy Division, Sonic Youth, Blondie, Soundgarden, The Cars, Melvins, Black Sabbath, The Breeders, The Replacements, The Beatles, Queen, it goes on... though some of them I'm still getting into. two TD's for saying edit? Piss off! BTW, those were all just from my own knowledge... I didn't look anything up, I've been thinking wayyyyy too much these past two days.
Oh man, nothing is more basic in electrical than Maxwell's equations. Again Kirchhoff's voltage and current law are it's special cases and without these laws even V=I*R fails.So MAXWELL EQUATIONS !
Every Electrician Should Know About Below Basic Things1. If you are not using a torque wrench to tighten electrical connections chances are you are over tightening connections and damaging the conductors. Additionally, over tightening bolts stress the material and the bolt can fail during an electrical fault. Most electricians over tighten connections (other than overlooking a connection and leaving it loose by accident). I have seen this time and again. If you remove the conductors and the strands are damaged, you most likely have over tightened the connections.2. If you are not using a Megger prior to energizing, after a fault, or anytime you have de-energized and are ready to re-energize, you are placing yourself, others with you, your customer, and company at risk.3. We hear engineers, customers, and practically anyone in the electrical field concerned about the “ground.” Most of these parties worry about the ground electrode, when in reality this is (IN MY OPINION) the least of our worries. The number one grounding issue I see that can affect customer sensitive equipment is, grounds on the neutral conductor downstream from the main neutral to ground bond (NGB). These connections can be accidental or intentional. A simple megger test of the neutral to ground prior to energizing the service (with the bond lifted) can verify the integrity of the neutral.
Electrical is not grounded need ac?
AC doesn't really HAVE to have a ground per se. AC often does have what's called a ground, and in the case of an electrical short, the current will flow thru this wire safely to ground. AC means "alternating current", and 30 of every 60 seconds one wire it HOT, and the other is 'neutral' or ground, and then the next 30 seconds that wire becomes ground and the other wire is 'hot. This is what's considered a 60 Hz (Hertz....a person'r name, meaning frequency) electrical signal. Get a window air conditioner and put it in already. Plug it in the wall and off you go....cool air. You'll be ok as long as you aren't putting too many deviced on one circuit, and if you are you will know because you will start blowing fuses left and right. Install it, plug it in and watch it and make sure everything's good. Feel the plug that's plugged in and see how hot it feels. It MAY feel warm, but it should not feel hot. I'm sure you will be ok, but if you have concerns....ask more questions.
What is the Difference between KW and KVA?The power factor is the real power (in kilowatts) divided by the apparent power (in kilovolts x amps) and is always between 0 and *When you work always wear special insulating shoes. They will isolate you from the floor and if you come under voltage the current flow will not go through your body.Current vs. Voltage :Current is the rate at which electric charge flows past a point in a circuit. Voltage is the electrical force that would drive an electric current between two points.
To get the basics, this is what I would do.This is from the standpoint of being formally a physicist, but having designed and built electronic stuff since I was maybe 8.You need to know the basics of what sorts of components are out there, where to get them, how they work, and what they typically are intended for.You need to know how to hack together a breadboard.You need to know schematic capture and PCB CAD. Any one of them will do.You need to know what electrical symbols are for standard components.You need to know ohms law and kirchoff’s law and what to do with them.You need to know basic logic.You need to know a little about microcontrollers and how to go about programming them and interfacing them.You need to understand what DC and AC mean and how to do at least simple calculations for both types of circuits.You should be familiar with power distribution systems in current use (1- and 3-phase AC).I’m usually not all that interested in the cheapest solution, so I’m leaving engineering economics out of it, but that’s a thing.Not necessary but smart to do is learn the old resistor color code. Not only will it help you with things like making sure you have the right parts when picking from a bin that everyone uses (and puts questionable parts back into contrary to common wisdom), but many things have been color coded using the same code. When developing, for example, it’s very very convenient to spend a little more on rainbow ribbon cable which helps you not get signals confused during testing.Get familiar with conventions, like very often DC power wires are red+ black- in the US and Japan, while they’re brown+ and blue- in much of Europe.Know the thresholds where power becomes painful to touch and where power becomes dangerous to touch and where it becomes dangerous to get close to.If you really do want to do anything sophisticated, become friends with mathematics.Edit: I forgot one very very critically important thing. Learn how to read data sheets. You can build one-off circuits all day long that work fine, but you cannot design circuits for sale into any market by hacking something together. You have to actually engineer it. And you can’t do that without component data.You don’t have to do this first, but somewhere along the line it’s needed. There’s a reason that component manufacturers go to the trouble of characterizing their parts and publishing the sheets, and the reason is that they want to sell more than one per engineer.
For safety reasons knowing proper electrical safety is imperative. By not becoming knowledgeable about electrical safety, one can become shocked, burned, or in the worst case scenario a person can be electrocuted which can lead to death.When working around with electricity one should be aware of the basic safety regulations.The most common cause of many electrical related accidents on a job site is faulty wiring.One should always use all of the power tool equipment properly as when it is misused it can damage the wires of the equipment for this reason.If there is any confusion regarding this you should readily take heed to the professional electrician of Northern Beaches if you live in Australia, for a proper residential electrical maintenance.An electrical fire can also happen when one plugs in too many power tools all at once to the extension cord.Into a two-pronged outlet for any reason, the three-pronged plugs on any type of equipment are never to be altered to fit into it.It results in the grounding wire becoming unusable and leaves the worker that is using the equipment unprotected from stray electricity when this is done.If you have young children or are planning to do work on your home you must make sure that you have some basic electrical safety training and electricity safety riles for every home which has electricity flowing through it.Without a proper precaution, electricity can kill very easily though this is the part of modern society.
LICENSE ELECTRICAL CONTRACTOR?
Seems this exact same question was asked 3 months ago. To save time I have copied the answers given back then. The first is from dtstellwagen who is a very knowledgeable electrician, followed by mine. Hope this helps. The process for finding the answer is easier than posting an answers.yahoo question. Enter philadelphia in a search engine. Click on the city website http://www.phila.gov/Pages/default.aspx , click "Building and Construction", scroll down and click "Electrical Permits". Then read: Electrical Permit Basics Only a licensed Electrical Contractor can apply for an electrical permit from the City Electrical permits are required for the installation, alteration, replacement or repair of electrical and communications wiring and equipment within or on any structure and for the alteration of an existing installation. An electrical permit IS NOT required for: Minor repairs and maintenance work, including: Replacing lamps, circuit breakers or fuses Repairing or replacing switches, lamp sockets, ballasts, drop cords, receptacles or bulbs, or for the taping of bare joints Replacing lighting fixtures in existing connections So, you must be an licensed electrical contractor, and replacing an electrical PANEL is NOT a minor repair. dtstellwagen · 3 months ago 1 Thumbs up 0 Thumbs down Comment Lediy99 I would assume so. And even if they aren't I wouldn't have someone do that (extensive) kind of work without one. Also, proof of insurance. Being able to show proof the work was done by a licensed professional under permit will add to resale someday. Or, you may have some explain to do to your insurance claims adjuster... Replacing a panel actually involves a good bit of Code and Mechanical skill. Not nearly as simple as folks think. I have (more than once) been called in to do extensive rework of a badly done panel change. Either because of damage to the house or a result of failing a home inspection prior to the sale of a house. It is money well spent I assure you!
