Wire to Console Batteries Advice
 

I'm thinking 2 gauge would probably be adequate if I run wires to a console battery, shouldn't be more than a ten foot run (20' round trip) if I do it going through the rigging tunnel. Is there any advantage to not running through the tunnel, chance of interference of some sort? I have the chance to run cables under the deck right now since the deck is completely off. That would add at least six feet to the round trip equation however in order to get the cables all the way to the rear corner box.

go to genuinedealz.com and use their calculator for gauge size and then have them make your cables. They do very good work, great prices and free shipping.

Ditto!!

How about a second tube for just battery cables?

my boat also currently has no floor, i was thinking about glueing or glassing a 1 1/2 inch pvc on the inside of each foam stringer so i can pull the wires thru when the time comes

that would be my choice, since you can

If 2" pvc will fit, go bigger!!

Ditto. and bigger than 2" if you can. You'll be shocked how fast a 2" rigging tube will fill up. I've got 3-2" conduits from the engine compartment in my 25. Two go to the helm, the other goes to the battery box. They're all pretty full.

I actually have a 4" going down where the old rigging went and a 3" in the other side. My old boat was stuffed to the hilt so I wanted room for expansion! If I go down the port side, I have to go across the bilge into the other side so that would be a long run. I was thinking of rigging a small tube from the console into the bilge and into the corner box by glassing it to the under deck, I'm probably over thinking things, lol. From what I'm reading interference isn't much of an issue with DC unless there is a motor of some type running so maybe I'll just use the 4" and then run the fishfinder transducer cable down the other side to keep my sanity. That's the main thing I would worry about anyway. That PVC drain pipe is really nice and light by the way for anyone that is doing this.

just a thought most pvc pipe is sch 40 if you get into the "sprinkler "pipe you can get sch20 that gives you a lil more room inside--thinner wall but the same od
