I am ready to get wires from FWF to cabin. From what I read, the 'high current' wires should be separated from the 'low current'. I gather the 6AWG wire from the master contactor to the main bus is of the 'high current' variety, but most of the rest of the wires are no bigger than 18AWG (field wires from the alternators, and the +12v power to the P Mags, for example).
So, what constitutes 'low current' and should be separated, or is this really the criteria?
Perhaps, a more appropriate question is which wires should not be co-mingled?
There are 16 wires coming through the firewall as far as I can tell at this point:
1. PMag P leads x 2 (20AWG)
2. PMag +12v leads x 2 (18AWG)
3. Starter Engaged light (22AWG)
4. Main Alternator Offline Light (22AWG)
5. Starter Button (20AWG)
6. Alternator F leads x 2 (18AWG)
7. Hall Effect Current sensor leads x 3 (22AWG)
8. Master Contactor to Main Bus lead (6AWG)
9. Master switch lead (22AWG)
10. Stall horn (20AWG)
11. Baggage light (20AWG)
