Re: Signal wire gauge and color.
R46:

Quote:
<R46> All active Power Distribution Board branch circuit wiring with a constant polarity (i.e., except for relay module, speed controller, or sensor outputs) shall be color-coded as follows:
A. Use red, white, brown, or black with stripe wire for +24 Vdc, +12 Vdc and +5 Vdc connections.
B. Use black or blue wire for common (-) connections.
So for a pot, you will have common (black or blue), +VDC (red, white, brown, black w/stripe), and wiper (anything you please - but avoiding the same colors you used elsewhere is a good practice. Usually I use yellow or white for signal).
