I am replacing the wiring harness in the mast. I have a tri-color and anchor light at the top (both LED), and a steaming light and some hefty deck lights at the spreaders. I've done a ton of research about voltage drop. I've found and used many of the tables referenced elsewhere here in Sailnet. It appears that if I follow the reccomended guage for AWG marine grade wire to achieve the suggested maximun 3 percent voltage drop, I would be adding roughly 10 pounds of wire in the mast. Compared to what has worked for the last 30 years, wiring that big seems a bit excessive to me.
I would like to hear some thoughts about what works in the real world. Thanks in advance. - r
