Title: Wire gauge
Post by: lew on December 20, 2006, 03:00:35 PM

Another question.
I'm using Gecko's and Mach3. Just now building the system.
Wondering what recommendations for wire size?
I'm using 12awg. from the torroid to the capacitors but don't think I need or can use this size for power to the gecko's and out to the stepper's.
What should I be using from the gecko's to the steppers and what should be used from the power supply to the power and ground on the gecko's?
Thanks in advance.

As long as you know the voltage and the maximum power required you can work out the cable size.

formula :- watts/volts = amps

So 1000/240=4.16 Amps

Or 1000/120=8.33 Amps

16 AWG will take approx 15 Amps
21 AWG will take approx 2.5 Amps

All you need to do is pick a cable of this rating or higher.

The table gives a guide as to the AWG to MM2 conversion
