[amsat-bb] G-5500 Rotator Cable

[Mail]

You have 8 wires and only need 6. So, just double (or triple if you want) up on the 22g and use that and the two 18g wires for E4,5&6 and A4,5&6. Those are the only ones going to the motor and the only ones needing to handle high currents. A/E1,2&3 only carry low currents for the positioning potentiometer. 

Two 22g wires are approximately the same current carrying capacity as a 20g wire. Three would be closer to 19g equivalence. For short runs you can get away with a lot, but for longer runs, I’d go with the heavy duty line.
