    It's the same here, we can't work on elevators.


    If I were to run 208V 3 phase to a disconnect then I would label the disconnect with the voltage provided and that's it for me. I run whatever is shown on a drawing or provided on the work order.

    I think that if an elevator company had the electrician doing more than that it would be wrong.

    I don't think ECs in RI or CT can wire elevators that carry people either.

    Not doubting it's true, I just wasn't aware of that.

    Innocenct -Elevator power hook up

    Hi everybody again,
    About my case'

    All I did here , just provided 208V, 3-phase power through a properly sized disc. switch & all wiring material according to elect. Engineer design/plan to the elevator machine , or all the way to the starter's in-coming lugs which are called T1, T@, & T3.

    After that point elevator technition configured & installed wiring.......

    Elevator rating was: 200V, 3-phase, 100A & the starter wired by technicians was for Delta configuration .
    I think they did not read the fat note or sticker on starter stating "Starter wired for Delta configuration, damaged could be done if power supply is other than Delta"

    I think they have to configure wiring from starter to motor for in-line configuration.

    Don't you all juries thing that I am innocent here.

    A 200 volt rating is a NEMA rating for a motor on a 208 volt WYE system, there is no such thing as a 208 delta, I would believe this is the manufactures fault as I can't see how it can cause damage if wired on a WYE system and the fact that they supplied it rated for 208 volts which is a WYE system and one of the most common three phase voltages in the US.

    A starter is nothing but a set of contacts how can you wire it delta or WYE? that just does not make any sense, some motors can be wired WYE or Delta but not a starter.

    Here is a NEMA voltage chart, notice the listings for motors, a motor designed to run on 208 will have a 200 volt rating.
