I have a dust vacume with a stop start located on the unit 12''away from the motor if i set the disconnect next to the motor and have it lockable can I remove the stop start and locate it in the wood working area ( remote ) run the load wire back to the motor,will I still be in code? or will I have to provide a second stop start and disconnect for it ?

Does the Start/Stop operate a starter? If so, the Star/Stop station location doesn't need to be tied to the disconnect, it is the starter that is discussed in 430.102(A) not the S/S station. Is it possible you are trying to provide a disconnect for the S/S station?

I have designed electrical for dust collectors in high school shops, installed the equipment outside, and put the start/stop in the shop area as you described with no problems, I just left the motor starter outdoors.

the disconnect is for the motor

the disconnect is for the motor

and controller 430-102, 430-106, 430-107, the stop start pulls in a contactor
coil with a 230 volt coil the stop start are all in the same dust tight housing
430-012 and 430-107 state the controller MUST be in sight of the machinery or load ! sounds to me like a safty issue and trouble shooting the motor issue but is clear when it say's must
 
Sorry - having a hard time understanding the layout. As I understand it you have a contactor and start/stop in one enclosure. This is the motor starter, aka controller. You MUST have a disconnect within sight and within 50ft of this controller. IF this disconnect is lockable, then the disconnect at the motor is optional.
 
69jag,

You may be better off replacing the controller or start/stop control with one that has a remote option or extend the existing control. This way you still have the controller at/within sight of the equipment, and you will also have an additional set where you want it. There are some pretty good diagrams of how these are wired/operate on pages 49-50 of the 2005 edition of Ugly's Electrical Reference.

One should be able to tap into the existing controller's start/stop circuitry to provide remote operation. Simply use the same type operators, wiring the start in parallel and the stop in series.

That is essentially the same as what I said. Be sure to recheck your conductor fill on the controller's enclosure, because you may have to have a larger one just to extend the start/stop functions from the controller to a remote location.

Also back to your original post (particularly since you are extending a starting control to a remote location), I would still place a lockable disconnect before all of the starter control circuitry.
