FAQ

Fires are classified by the fuel involved. Name the type of fire extinguisher which must be used in the event of the each of the following fires 1. Cooking oils 2. Flammable liquids 3. Electrical equipment Thanks.

For cooking oils, greases and paints or Flammable liquidstype B while electrical equipment its type C fire extinguisher.

I have a school project (Construction management) that involves the estimating of the electrical cost for a building addition. I can do the fixture counts, equipment hook ups, box counts, switches and etc. I cant figure out how much wiring would be involved. from the blueprints, is there a way to measure (estimate) the lf of wiring? this is a school building so there are mostly medsize room and hallways. any help would be great. I remember something about the homerun count from when i was a laborer, but could i figure 1 line around the room with a line for fixtures or something like that. doesnt have to be perfect by any means.

Figure out the load for each room. Remember the vacuum cleaner rule. Figure out where the source is (panel or sub). Then run each line (including upsdowns) to each outlets, add 2 feet at each outlet - add extra afterwards. Not sure with school codes for electrical, but say for kitchens, you need 2 sep circuits for the top, circ for fridge, circ for DW circ for GarDisp. etc. Each circuit starts a home run. You can probably find circuit requirements online somewhere. But If it really doesn't matter Put an outlet every 4 feet on the teacher wall. Use 2 circuits and stagger it. Use two more circuits and stagger them (vacuum) rule around the class room (maybe 2 for each wall). (New schools use WAY more power, elect smart boards, laptops, comps, etc). Just get the drawing, imagine what you'd want - draw the runs and add it up, otherwise use the plans. Just think, each circuit comes from the panel, over to the room, to the first outlet, then the next, (dont Y or branch out), and then the last circuit. It's clean, simple and easy. Wires comes easily purchasable in the following lengths from your favt box store. 50,100,250,1000

(1) source would be from a house and another source would be from a battery [and may not always be on but when on should have priority over the house's power].

Yes, its called 220v. The same thing your stove and dryer are using. be careful its deadly.

I live in Houston texas and am planning on getting a degree in either electrical or mechanical engineering. What do they both involve? Which is better pay and more job offering?

Job outlook is the same. Salary. In most cases, electrical engineers get paid a little more ($3000-5000 more per year on average). But it is not always the case. It depends on industry, location, job hazards, job title, job responsibilities, education, and experience. For both majors, the starting salary range is $45,000-60,000 per year. After 5 years of experience, the ranges are around $63,000-73,000. After 20+ years of experience, the salary for both would be around $88,000-98,000 average. Mechanical engineers solve problems related to mechanical issues whether it is quality, reliability, maintainability related or HVAC and plumbing related, or if it is related to designing a mechanical component with strict tolerances. For example, my mechanical engineering friend is working on this hugs project. His company is developing just one of the gears that will go in future Subaru transmissions. He has to design that single gear to strict tolerances to withstand extreme pressures, speeds, and temperatures. Electrical engineers solve problems related to electrical systems. They design electrical systems for buildings and equipment, conduct electrical surveying, quality inspect circuit boards and other electrical parts. They design or improve electrical components as well.

(Warning: I have no knowledge of electrical equipment) I just bought a black light. It can fit into my lamp, but I noticed that the lamp had a label that read To reduce risk of fire, use a 60 watt type a lamp max. The bulb is 75 watts. Is it okay to use the bulb or should I not use it?

Please follow the directions on your lamp. The 75 Watt bulb will throw out more heat and need more power and your lamp is not rated for that. This could result in a fire. It is not worth the risk. Don't fool around with electricity.

I accidentally connected the negative and positive terminals of my battery with a wrench, I have checked all the fuses and none look to be blown. What else should I be looking for?

Your looking for a melted fuseable link-- noy a fuse. It will look like a burned wire

Hey im sell a electric fencing sword wet because I just cleaned it with water because im selling it on OKorder.

no that is a really bad idea, unless it specifically says that it can get wet you shouldn't get it wet. you should probably test it to make sure it works before you sell it because the water might if messed it up

I am 57 years old. MBA graduate with substantial experience in Electrical equipment maintenance. I have also experience in NDT.

My guess is that your age is a stigma, though nobody will admit to you that they won't hire you because of your age. They might not even be conscious that they are discounting you because of your age. Look around the office when you go for your interview. Is it filled with younger, or with older people? Do the regular stuff too: Go on the internet and research good interview skills. Practice with your friends. Ask your friends to critique your resume. Look up the company on the internet and come up with some specifics about why you want to work for that particular company. Yeah, that's a good point Your salary expectations might be significantly higher than someone half your age. Better check into that. Also, I have no idea what NBT is. You might edit your question so that people have a better idea of what your experience is. Good luck!
