JRM - you should have allowed more time for a reply especially since it is Thanksgiving. Now you have merely antagonized forum members.
For your layout size 14/16 ga main runs from power supply to terminal are fine. I don't use fastrack so am not sure what size connector is used to hook into the underside of the track. I assume 18 ga will fit which is fine. Some say power drops every 6/8 feet but in my opinion no such thing as too many power drops from track. The more the merrier especially on all three sides of turnouts.
