There was a brief talk about running DC 12V LED lamps and the required
1) Remember that for DC, the wire length is from source to device AND
BACK TO SOURCE.
2) There will be many sources on the Internet on this. From my copy of
Nigel Calder's Boat Owner's Mechanical and Electrical Manual, pages 90
for a 10% voltage drop on a 5 ampere load
Wire size Length in feet from source to device and back to source
3) From my limited experience with wiring, I take my estimated wire
length required to run the wire and then double it to allow for all
those bends and up walls and down walls. And for DC, possibly double it
again for the return leg.
