I'm rebuilding and therefore rewiring a 29' 1992 Excella Classic Airstream. All of my lighting, including running lights, will be 12VDC and it will all be LED. The running lights will be on their own individual circuits for the 7 pin connector. House lighting will be separate and may also be on more than one circuit. The original wiring was 14 AWG, but everything was incandescent. At this point I'm only talking about lighting. Is there any reason I want to run larger wire than 16 AWG? I'm pretty well versed in single phase 120/ 240 AC wiring, but I'm still learning DC. Where can I do some educational reading on wire gauge sizing for DC loads and circuits?
