This souns like a basic question until reading into it. When dealing with a remote motor from the MCC, there is typically run/stop pushbutton station at the motor and the contactor is in the MCC. At the motor there will obviously be the motor local disconnect, but there should also be a disconnect for the pushbutton station because by definiton, the pushbutton is a controller. Anybody have experience with this as how to only have 1 disconnect at the motor?
Or, does it make more sense to have the MCC only provide the power and put a combo starter disconnect at the motor? The MCC usually has a hand/off/auto switch as well which is why the contactor is usually in the MCC. I believe hand lets the pushbutton station work, off is obviously off, and auto is alwas on I think. There are also red and green LED for motor run and motor stop.
Thanks
