    This is the BEST post on this thread yet!
     
  2. Completely wrong answer!
    The air flowing through hose creates lots of flow resistance also.:rolleyes:

    Thank you sir. I've tried to give electrical advice over the 'net and it just doesn't work, I don't really know what's going on with the original poster, I don't know his setup, equipment, or the condition of his service. For me to advise him to perform work without having that knowledge is wrong. I've done it but I'll never do it again.

    Oh, I am an industrial electrician and electronic repairman (according to my job ***le). We did everything from initial design right up to installation and start-up in a fully integrated and high speed production facility.

  6. Get ready to pay through the nose. Also if I understood, you live in an apartment. You cannot do any electrical in it. Making a cord out of SO cable is still the cheapest and only legal way that won't get you in hot water with the apartment owner.

    I'd have to disagree with ya Rabid, I priced out doing a service change for a friend last year, the electrician in a van was able to do it for LESS than I could buy parts! This economy is motivating some folks pretty darn hard. Also, if he is in an apartment and needs to do an extension cord of some sort, better to pay an electrician to line you out on what parts you would need, rather than going to the big box store and having the Home Depot "expurt" design a giant match for you!:p

    Well. The electrician was in at work today. Talked to him. He said running a 10 gauge 220 volt cord from the laundry room is my best bet. It's a 30 amp breaker wired with 10 gauge. He said it would be easier on the motor at start as well. Can get me the flame and oil resistant cord for cheaper than i could buy it at the deep.
    Also, I talked to my landlord about this before I embarked. He was fine with having an outlet installed, but i had to pay for it.
     
  9. good to hear- you DID get that in writing right?
     

  10. Bingo! Best bang for the buck.

    Now how would the electrician get the wire from the panel which you said is far away to the garage? Tearing up drywall and repatching and painting will cost a fortune.
    The cord can go with you where ever you go. Usually the breakers in Apartments are filled with no room for an extra 220 breaker and alot of the breakers I have seen in apts are peanut/mini breakers. Thats also something to ponder.
    Use the cord luke, use the cord!!! LOL

    I can take it with me and will have it for years. No sooner am i going to get the cord made and the compressor is just going to explode lol. A work in progress
    It wouldn't have been that bad to install an outlet. All of the service, laundry included is in the ba*****t, and there are plenty of open slots in the panel. Not a finished ba*****t either.
    But that is neither here nor there. May the cord be with you
     
  12. I buy all electrical at Electrical supply houses like Stoneway or Platt. I also can get the cost for about the same as the Electrical contractor price. Actually a funny story is that I could actually get a breaker walking off the street cheaper than my electrical sub for $30 cheaper. Lets just say, he had words with the supply house as he deals with $100,000s of with them. Some parts are actually cheaper at the big box stores than the supply places also. Anyone can get their electrical parts from Electrical supply places. A sale is a sale to them.
    When I ran my 100 Amp service to my barn, my supply wire was dirt cheap at Platt compared to Home Depot. But other parts are more. Its not like SO cable is very expensive. I believe its like .79 a foot and then you have about $20 in ends.
     
  13. LOL!!
    But remember, the cord could be used for your future tig and Mig welder also or you could use it to tow your car or to build a torture device. There are many many options for the CORD!!!!

    lol. Everywhere i've seen online 10/3 cord is listed at like $2 buck a foot. I'm gonna have to call one of the local electrical houses tomorrow. With all the money i save i can buy the ingersoll rand ***anium impact wrench :)

    I'll second KookKat-57

    The biggest draw for an electric motor is always at start-up...if it's going to trip, it will be then.

    Do it right and sleep at night.

    Personal experience has been the installation of several 3 phase and 220 compressors, and built my own 80 gallon 7.5 hp single phase Ingersol Cast Iron T-30, and a smaller Quincy Cast Iron single stage twin.

  16. I actually have mine run directly out from the panel and then use a 25 ft cord and a 60ft cord depending on where I weld.
