  1. I just checked my three miter saws with a...

    I just checked my three miter saws with a straight edge. All are straight. What brand saw do you have? I will want to avoid it. From what you are saying, a long piece of material would only touch...
  2. Yes, wire nuts are ugly. As Thermite said, that...

    Yes, wire nuts are ugly. As Thermite said, that is what the cover is for. This is the method that almost any electrician would use. What I find visibly offensive in a junction box is if the wires...
  3. I don't see where any of your proposed solutions...

    I don't see where any of your proposed solutions is any more compact than just using wire nuts.

    Run your wires in a circular pattern around the inside of the box and cut the length of each wire...
  4. You probably should have put this in the forum...

    You probably should have put this in the forum dedicated to this type of issue.

    I doubt it is the motor. If all the windings have the same resistance and there is no path to the case and all...

    I don't see the pictures. So just guessing extent of damage. One concern is that smoke can be quite acidic. This of course can lead to corrosion that will continue to occur indefinitely. This...
  6. First a note for electrical terms. Since you...

    First a note for electrical terms. Since you correctly did not use the neutral you did not apply 120 volts to anything. Hopefully you applied 240 Volts to the RPC (check the voltage between the two...
  7. As stated in an earlier post, the power factor...

    As stated in an earlier post, the power factor correction will only reduce the current a very small part of the start up current of approximately 150 amps. Power factor correction is usually sized...
  8. The wire size to the compressor is not as...

    The wire size to the compressor is not as important in this case as the size of wire to the panel as this is where the voltage drop is measured. I agree the shut down current sounds high but the...
  9. First I will say I have no knowledge of the the...

    First I will say I have no knowledge of the the Ebay crimper. It might make sense if you need to get down machinery back on line in a hurry. The vast array of fittings required would make me...
  10. I second putting a current meter on it. I also...

    I second putting a current meter on it. I also agree if it is lugging down the check valve is a good place to look.

    But if it is slowing down as much as you say there should be smoke coming out...
  11. As Diving Doug says try it. But don't be...

    As Diving Doug says try it. But don't be surprised if it does not start. I would not expect a 3 HP RPC to put out 15 amps three phase. It may draw that much from the single phase but the output...
  12. I would contact Phase-Perfect. We would be...

    I would contact Phase-Perfect. We would be guessing the frequency spectrum that is causing the problems, its amplitude and other parameters. They should already have solutions that have been...

    You really don't need to add a complete phase...

    You really don't need to add a complete phase converter. You need to just connect the 15 hp motor as a load (after starting the RPC) and it will then make your 40 hp RPC a 55 hp RPC.

    Wire it up...

    Tom,

    What I understand after questioning the same thing is that he wants to use it to kill incoming power to the VFD when done for the day instead of using the door switch on the cabinet or going...
  15. Yes you could follow the door inter lock with a...

    Yes you could follow the door inter lock with a contactor operated by a front panel switch. Contactors are not single phase or three phase but rather have some number of poles with two required as...
  16. For what purpose do you want a contactor? To...

    For what purpose do you want a contactor? To answer your question directly, lots of single phase contactors are still made.

    You should have a means of disconnect (either plug connected or a...
  17. Because I an old guy I would have taken an analog...

    Because I an old guy I would have taken an analog approach. A function generator chip a handful of components and done. No programming. A couple of pots to adjust amplitude and frequency and maybe...

    Your ground is currently connected to a metal pipe. By code the metal pipe (both water and gas) are bonded to the electrical grounding device (ufer or rod). So, you will just be taking a more...
  19. I am an amateur also but I noticed something...

    I am an amateur also but I noticed something others did not mention. You said that the drill wobbled when drilling for the live center. This is not a result of the bar being off center. It believe...
  20. I know nothing about European power but you are...

    I know nothing about European power but you are probably correct that their power consists of a hot let and a neutral.

    Wall warts have to be make to safety standards and I am sure that would...
  21. This is certainly not my field of expertise but...

    This is certainly not my field of expertise but my concern is knowing what alloy the swing arm is made from and what the welding requirements are for that alloy. The motorcycle manufacturers have...
  22. As JST stated the VA capability will be halved. ...

    As JST stated the VA capability will be halved. VA is shorthand for the implied math of Volts times Amps. The VA of the transformer will be half of the rating which in this case is half of 3 KVA...
  23. Stuart, Yes it will work great. No smoke. ...

    Stuart,

    Yes it will work great. No smoke.

    Three phase power is just three sets of single phase power with a time difference between each of the three phases. All that matters is the voltage...
  24. This is incorrect. However what you say would be...

    This is incorrect. However what you say would be correct if you substitute "WYE" for "Delta".
    Wye has a neutral in the center. Delta has no center. Even with a WYE in which there is a phase shift...
  25. Between any two wires the voltage is 180 degrees...

    Between any two wires the voltage is 180 degrees out of phase. Without a third point reference point there is no 120 degree phase shift. And since you are only using 2 wires it is just single phase...
