According to the Vancouver Sun interview with Gavin;Q: What is the future for waterfront cities like Vancouver?A: You are going to have to put up with rising sea levels; they are not going to go down. But there’s a huge difference between a foot or two over 100 years and a metre or two metres. There’s a lot of waterfront development going on but is it sea-level-rise smart? I don’t know that it is. So don’t put stuff in the basement, have all your electrical equipment on the second floor or on the roof.

That sounds a bit simplistic. There are houses in Europe that are periodically flooded with little problem, but they are older brick or stone-built structures that pre-date electricity. Vancouver homes with gypsum wallboard and carpet or hardwood floors aren t going to fare so well.

I am studying in college to become an electrical engineer but there is one problem, i'm almost clueless about what i'll do once i graduate. like at what kind of companies and places will i work at? what will i be doing? whats it like to be an engineer? what will be my dutys?. and also how much does an engineer (more specifically the kind in my field) earn? really need to know this. thanks

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.

Electrical Blueprints

I'm 14 and I go to a technical highschool, I'm in hvac because I missed electrical by 1 person, if I get the chance should I switch to electrical? I already have my tools and uniform.

What interests you the most? There is employment in both fields, and both pay good. You'll have to be a journeyman, no matter what before you get a master's license. I would frankly stick with HVAC because you will learn electrical stuff as you go along. I worked as a technician on food service equipment and vending machines for 20 years. There are a LOT of HVAC technicians and refrigeration technicians who also hold electrical licenses, but very few electricians who have licenses in any other area than electrical.

I live in a condominium made of concrete without an electrical ground wire. Is it possible for me to hammer a nail into the concrete wall and attach the ground wire onto the nail. Will this be effective? If not can anyone please suggest a method for me to be able to ground my appliances. Much thanks in advance.My country/city has almost no electrical regulation/laws and the little that we have are barely implemented and never inspected.Safe DIY Guerilla methods are accepted

Wisdumb, no, this will not work. A ground provides a substantial electrical connection to *the ground* one way or another. In the U.S, to provide a ground for a radio or T.V. antenna, a long copper-coated stake is driven into the ground, and the area around it is covered in salt to assist conductivity (water or rain dissolves the salt into the surrounding soil). A thick wire is then attached to the copper stake and then run to the antenna and mast. This may give you some ideas, but may not be fully effective for your needs. Maybe an electrician will answer. Good luck. Don't kill yourself.

I am about to finish my BS in Electrical Engineering and was considering getting a MS in EE but considering how the economoy is and the fact that the Bureau of Labor Statistics say it should grow slower than average. This being said what do you guys think is the most prudent thing to do in my case. Go for an MS Engineering Degree or start out with another degree maybe in healthcare.

As per research, the job growth of electrical engineers will largely occur in engineering firms, government agencies, industrial sectors, and more. These engineers will also experience tremendous job growth in computer systems design, because these industries are focusing on manufacturing portable computing device. The rapid pace of technological invention will drive huge demand for electrical engineers in the research sector as well. So, those who're thinking of pursuing electrical and electronic engineering will experience favourable employment opportunities in the years to come.

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.
