The 4 core cable we have will be fine, i only supply one type of 4 core, so it can be used on all the motors we sell (All the way up to the FL86)
The 8 core cable is signal cable and should not be used for the motor phases.
If the cable is not man enough and burns and goes open circuit, it will damage the driver, and going larger than needed will not cause any problems.
The fuse rating depends on the current setting of the driver, but if you use a fuse about one amp higher than the rated current that should be fine.
Put this on the DC going to each driver.

Ok, I have a question......

What cable should I get to drive the steppers? I have bought some 8 core shielded from Zapp Automation but It is probably too small for driving the motors. Zapp have some 4 core on their site but that looks too big, more like mains cable. Anyone have a link to some 4 core to do the job?

Also, the Stepper drivers are rated 4.2A peak, what size fuses should I use?

As you can tell, electrics are not my strong point ;)
