  1. it's a tough call as to what sucks more, mexi-narco pipes, chinese copper
    plated lead or the government meddling.

    True, but the current will be higher because of power factor.
    But, that was not what I was curious about. What I want to know is, if
    the running current results in a 3% drop, doesn't that result in a 18%
    drop when the current goes up 6 times?

    Really? S.E.D having an absurd conversation? What's your point?

    You guys are all pretty ridiculous calling each other names and such,
    but at least you know how to trim a post. Thanks. It makes it easier
    to get through this crap.

    It is really strange person that thinks that Grainger or McMaster-Carr are
    the low price outfits. Their prices resemble Radio Schmuck versus online.

    Tough chips Keith, Michael is right on this one.

    Why not put the compressor where the power is, and run an air hose?
    That's the best idea I've heard yet.

    Sadly, he had already located the compressor, installed the air lines, hooked
    it up before calling me to wire it. He placed it right next to the main
    air-user, the mechanic's bays. (It's an auto repair shop.)

    It depends on several variables, including motor size, motor winding
    class, number of phases, design of motor start system, and some other
    things. Very small motors may start at 2x FLA, some very large (full
    voltage start) motors may require 20 to 30 x FLA.

    Bullshit.

    So show us your numbers instead of more diarrhea of the mouth, as is
    your normal MO.

    You lefties are always projecting your inadequacies.

    At least your rants are short (I mean all of you). Thanks, makes it
    easier to breeze through the muck.

    Instead of incessantly whining, you could just ignore me. No, you
    lefties are too stupid to do that.

    Well I'm not interested in being quarrelsome but would you mind
    explaining why you would use copper piping for air lines. Copper has
    gotten more pricy rather than recently pricey so it would seem to be
    rather a waste to use it for air. Help me out here. What am I
    missing?

    In North American Practice the electrical codes forbid assembling
    conduit around wire. The conduit must be built as a complete assembly
    and then you pull the wire from pull point to pull point.
     
  18. Guest

    A reasonable alternative.

    I've seen the pipe fitters install hundreds of feet of black iron on
    jobs with a lot of air in use such as assembly lines. What is wrong
    with that? Is it too expensive to install to be cost effective? I
    have been out of the big job work for over a decade now.
     
  20. Guest

    Black iron is incredibly expensive and impossible to work with.
