  9. See what I make?

    By the way I don't work in that Factory anymore. It payed only $10 an hour.
    I was a machinist (so to speak). I drilled holes, grinded parts ,used the Milling machine, Metal benders, Metal Punches (that shook the ground when the punch came down), metal lathe, large drill press, etc. then assembly.
    I had no part in the design. I was a general laborer, that just did as I was told.

    I work back at my old job now making over twice that much money.
    I am a Service Tech

    What exactly is a "gang operated airbrake"?



    GANG-OPERATED DISCONNECTS
    Gang-operated disconnects are used where more than one phase of a circuit must be opened simultaneously. The most common gang-operated disconnect switches are the air-brake type manufactured in 200-, 300-, and 400-ampere ratings in all voltage classes from 5,000 volts up. They are used at substations, switching structures, and on the lines for energizing and de-energizing transformer banks and other apparatus. They are also used for sectionalizing. Although they can be motor-operated, they are more commonly provided with a switch handle for hand operation. This type of switch is ideal because it lends itself to operation from the ground, often permitting service to be restored to sections of the network without pole climbing.

    Believe it or not the Earth is the 4th wire.
    That is why they call it Ground.

    Read more about it here.
    http://www.seas.upenn.edu/ese/rca/instruments/misctutorials/Ground/grd.html

    Take a look at his site.
    http://en.wikipedia.org/wiki/Electric_power_transmission

    And this one.

    Here is OSHA's Definitions for Ground.
    http://www.osha.gov/SLTC/etools/electric_power/glossary.html

    Ground: A large conducting body (such as the earth) used as a common return for an electric circuit and as an arbitrary zero of potential.

    Grounded, effectively: Intentionally connected to earth through a ground connection or connections of sufficiently low impedance and having sufficient current-carrying capacity to prevent the buildup of voltages that may result in undue hazards to connect equipment or to persons.

    Grounded Conductor: A system or circuit conductor that is intentionally grounded, usually gray or white in color.

    Grounding Conductor: A conductor used to connect metal equipment enclosures and/or the system grounded conductor to a grounding electrode, such as the ground wire run to the water pipe at a service; also may be a bare or insulated conductor used to ground motor frames, panel boxes, and other metal equipment enclosures used throughout electrical systems. In most conduit systems, the conduit is used as the ground conductor.

  20. Understanding test conditions in any Datasheet

    in Datasheet/Parts requests

    Yes, you got it. The Test circuit would be a great starting point but, pay attention to the maximum allowed voltages etc. Alot of Datasheets also have actual circuits that are already designed for you. Here is an example of what I am talking about. Look at this Datasheet for TDA2003 There is a test circuit but the actual circuit they provide you has already been figured out and a PC Board design is there as well.
