Any test equipment that your life may depend on when using it must first be tested before being used. These types of test equipment usually have internal apparatus that can verify that the equipment is working perfectly before it is used by personnel. Linesmen use this type of test equipment before working on primary voltage lines.

What is the national electric code?
The National Electrical Code is the recognised standard to which all electrical wiring and installations must adhere to. It is a requirement of selling a house that all wiring and equipment must feature this code to prove it has been correctly fitted.
How far does an electrical panel have to be from a side wall?
Working space around electrical equipment shall be minimum: 30" wide and 36" deep and 6'-6" high. The panel door must be able to open at a 90 degrees angle.
Why is special fire fighting equipment needed for electrical and non electrical fires?
Water conducts electricity and is therefore contraindicated for use on energized electrical equipment, however it is much cheaper than the chemicals that can be used on energized equipment making it more economical when water is able to be used. Similarly water should not be used on grease fires as it will spread out the grease and the fire rather than smothering it. Water if pure without contaminants does not conduct . Having stated that electrical fire can hardly be contained by water since the air itself will conduct electrons by ionization. So to contain an electrical fire a the oxygen must be removed and water will not do that.
Can HVAC duct passing through the electrical room as per the NEC code?
Obviously, an HVAC duct or pipe can pass through an electrical room, as described in the NEC. It cannot pass directly over or under panelboards, and elctrical equipment must be protected from condensation or drips form the pipe or duct.
What is meant by switch gears in electrical engineering?
To protect the system from faults the equipment used is known as switch gearAnswerSwitchgear is the generic name for transmission and distribution equipment designed control, disconnect, and protect an electrical system. Switchgear includes circuit breakers, fuses, and isolators (US term: disconnectors). As well as being used to control circuits by opening or closing those circuits, circuit breakers are designed to interruptand to close onto electrical faults so must incorporate means of extinguishing the arcing associated with such faults. Circuit breakers, therefore, have a essential role in responding to protection systems. Isolators are non-load breaking switches, designed to isolate equipment (including circuit breakers) from high voltages, so that the equipment can be maintained.
What electrical equipment be tested for before it is used?
Any test equipment that your life may depend on when using it must first be tested before being used. These types of test equipment usually have internal apparatus that can verify that the equipment is working perfectly before it is used by personnel. Linesmen use this type of test equipment before working on primary voltage lines.
What should you do before using electrical equipment?

Can we provide Common earthing for ac and dc equipment?
Yes, the electrical code states that all electrical equipment must be grounded.
Do you need to ground ceiling fans?
Answer for USA, Canada and countries running a 60 Hertz supply service.The electrical code states that all electrical equipment must be grounded.
Which steps must take place before the pharmaceutical company can test the drug on human volunteers?
Must be tested by animals first.
What action must be taken with EEDs before preforming an electrical continuity electrical repair check on an explosive facility?
Depends on the type of EED and the test instrument. With a current limited test instrument and a reasonably high power EED continuity can be tested. But with a regular instrument and sensitive EEDs it's best to disconnect them.
If rubber goods are tested and inspected in house, the individual or individuals performing the tests must NOT test and certify their own personal protective equipment.?
True.

The National Electrical Code is the recognised standard to which all electrical wiring and installations must adhere to. It is a requirement of selling a house that all wiring and equipment must feature this code to prove it has been correctly fitted.
What training do I need for an electrical engineer job?
Electrical Engineers require a degree from an accredited university if they wish to have a fruitful career. Hopeful electrical engineers must be great problem solvers and reasoners. The knowledge of current and future equipment and technology is an absolute must. Electrical Engineers must also have a strong knowledge of mathematics and the sciences, as well as their applications. http://jobs.virginia.gov/careerguides/electricalengineers.htm
Does electrical shock from an outside source interfere with the function of a pacemaker?
if the shock crosses the equipment then yes. it must also be a large shock
What is the difference between electrical PVC and plumbing PVC?
electrical PVC is not bar pressure tested and is therefore quite thin and does not contain certain chemicles in the pipe to stop water corrosion where as plumbing PVC pipes are tested and generally thicker and must be in order to prevent burst pipes and pressure spikes
How do you operate a new appliance or equipment?
You must read first the instructions in the manual before operating the new equipment to avoid errors.
