    Thanks for helping me to look at that thing from a different perspective.

    And thanks for your perspective.

    I know you and Jayguy are 2 of the most knowledgable people on this site!

    We all know how the starter works.

    To be precise, the motor will only see an inrush current of exactly 133% of the Full load amps during the wye configaration. Compare that to up to 800% Full load amps when starting Delta or "Across-the Line" start.

    Lets go back to electrical 101. The reason it is refered to as a reduced voltage starter is that the applied voltage passes through multiple windings, thus voltage is dropped at each winding. Hence, the term reduced voltage. Who would have ever imagined that a simple starter would arouse this much traffic.

    wel put

    this is a quite good and accurate description. As I said , it has been about 12 years since I had ot work on one of theese. I will look Monday and see where the time delay relay is in the circuit. It aslmpost has to be the delay between the two contacgtors on this starter. It was set for 6 minutes. I can't imagine how tnhis worked as a contactor delay on any type of starter.

    electrical 101 says that there is voltage drop across ALL windings no matter how many there are in series...1 or 2 or 1000.

    does this mean that all wye wound motors are reduced voltage motors? if i build a motor with 4 windings in series (instead of 2, but of the same total horsepower) will my motor be considered a 'Super Reduced Voltage' motor/starter? will this make my starter have a lower inrush than everyone elses?

    (the answer is no)

    I could make the argument that the wye delta motor/starter is a reduced voltage motor/starter due to the fact that the same motor (and starter) terminals (T1-T4, T2-T5, & T3-T6) see a reduced voltage when connected in wye as opposed when the exact same terminals are connected in delta.

    That has nothing to do with the wye delta starter. I believe that you like to hear yourself type at times. Try not to overthink life so much.
