    hey Micro, i noticed you were located in Fernley, pretty damn close to where my parents are moving, Fallon....i was curious as to how much work is available for electricians or apprentices in that area? I am in the process of becoming an apprentice here in California with the IBEW, thanks for any input.....Allan

    Hi there,
    Was reading one of your previous posts about 3phase motors connected for wye-delta starting. I have a 6-lead motor that needs to be connected to a wye-delta contactor setup, but the motor leads are just 2 labeled T1, T2, T3. Does it really matter what the polarity of the windings are, and if so how do I determine this is they weren't labelled from the rewind.

    Thanks in advance,
    Corey

    If the 480 side of the transformer is a delta connection (almost all of them are), there is no place to land the neutral.

    It cannot go anywhere on the low side; they are different systems.

    A delta connection on the primary side of a transformer, by its nature, is a 3 phase 3 wire connection.

    A wye connection can be 3 phase 3 wire, or it can involve the neutral. This is because a wye has a common point where all 3 coils are connected, a delta does not.

    Once you connect a couple of them, 3 phase transformers are actually easy.

    Best of luck,
    Rob

    Rob, i'd just like to thank you for your posts here: http://www.electriciantalk.com/f2/tr...-feeders-3433/

    In hours of reading today for connecting the identical transformer, so many posts or responders forget where they come from.
    Not everyone connects transformers often and in a competitive market sometimes you just have to learn on the fly. You gotta learn somewhere.
    I do have my old boss (who's like 80 now) to guide me, but it sure as hell helps to at least sound like i know what i'm talking about when he comes by for guidance.
    Your post was not only the most respectful but very informative.
    Enough so that i joined this forum to send you this message.

    I'll end this with one last question, that at this point i do not fully understand, if i'm reading this right, i do NOT need to bring the neutral in from the 480 panel?
    Is that right and why?

    I appreciated your input.
    Thanks,
    Joe
