Sorry guys,

Maine_Sail and sailingdog are right. That'll teach me to use the handy (lazy) tables.

There is a better tool that I have used to calculate the appropriate wire size. It is a program called "wiresizer.exe" - from Alden Trull Yacht Electrical Design. If you are into this kind of thing, here is a link.

After running it, the appropriate wire to power this 0.8A light would be AWG 16 which yields a 2.778% (or 0.333 volt) voltage drop.

So the long and short of it; the 14AWG is fine, and slight overkill!

(Can someone lend me a towel? I need to wipe off some egg....)
