Hello everyone, first time poster, long time reader.
I have some questions for y'all
1) First of all what are the differences between motor starter and disconnect
2) Can someone give me an example of a starter that is not considered as a disconnect? And how can one distinguish the difference.
Ok so.......I'm developing the electrical drawings for a motor that will have the option to rotate something 12" to the left and 12" to the right.
The motor rating is 3/4HP, 208-240/460V, 3 ph, 1200 rpm TEFC motor with end of travel limits. The motor is ~50m away from the control room.
So my questions are:
3) The voltage rated are they all 3 ph voltages? from 208-240 and 460?
4) Where to place disconnects and/or starters? The CEC states that a means of disconnect should be 9m away from the motor (28-604).
There will also be a controller sending signals to the motor to go left or right and this will be in the control room 50m away from the motor. I think that a starter and/or disconnect should be placed near the motor with the controllers in the control room and it is breakered with a15A breaker in the LP.
5)What type of disconnects?
I'm thinking the one near the motor be Across the line and disconnect in one? Or can the across the line behave like a disc?
The one in the control room would not be a disconnect but a push button (left + right) to control the across the line starter
6) How is this shown on the SLD and elect layout?
- The motor should be circuited to the panel
- the starter and disconnect should be near the motor
- But not sure how the control buttons should be shown on the SLD, layout and how the wiring should be shown. Where would the push button's wires go?
Thanks!
