ribbon cable ampacity

Hi Everyone,
I need a flexible cable assembly between the base and the gantry on my 3 axis
router and am considering ribbon cable. The bend radius is 1 inch. Is it a
good idea to use 28 AWG gage ribbon cable for carrying the power and control?
The stepper drivers will be mounted next to the motors to reduce the noise,
and they are rated at 3 amp/24 VDC. The rest the conductors would be low
current step/direction and limit switch wiring. I've tried to find out how
much current 28 gage will handle - would anyone know.
cheers,
Denis
