What gauge wire for motors and drivers etc?

[JAZZCNC]

Thanks Jazz thats very clear and as I expected, however few more questions if I may:

- What to do in case of using connectors for example like this one http://www.automationtechnologiesinc...h-connector-12 where drivers are connected to patch cable with this connector?
do I ground the patch cable only? the shield on the long cable to motor would be left as is in that case.

- With that cable in your photos how are able to distinguish the 3 black wires from each other??

thanks!

Same idea because the 4 pin connector is not used at the Drive end. To keep shield continuity the Connector will probably have a shield connection point. If not then create your own by soldering or trapping shield on the connector body.

The Black wires have numbers printed on them you just can't see them in pics. But for safety and piece of mind it's also a good idea to check continuity as you go along like neil says as it's very easy to get wire in wrong place, even with coloured wires your eyes go wonky when it starts looking like spagetti.!!
