12VDC wire?

Recommended Posts

Wiring the 12VDC circuit in fish house and have a few questions:

1. What gauge recommended 14-2 or 12-2?

2. What type of wire are you using? Stranded? Marine grade?

 

thanks

I used individual wires in 12 ga. Stranded. My only 12 volt was for truck lights (tail lights, markers, etc). With the weight of today’s houses why not just have a generator with? For quiet time’s, battery operated LEDs last forever.

It all depends on the load you intend to be using. The higher the amperage draw the thicker the wire you will need so it doesn't overheat the wire. Led's use a fraction of an amp. 12 gauge is for heavy draw and is what I use for an extension cord from the generator to my house.

Voltage drop needs to be considered as well that is the only reason why I am thinking of just going with 12 AWG. I was just thinking of buying a roll each of red and black stranded THHN for 12VDC but curious if that be a bad idea and should use something like a marine type cable but that seems over kill?

Standard auto/trailer lights, clearance, signal, break etc. use 16AWG wire. There based on 13.8vdc (altimeter charging voltage) with a 5% volt loss for wire length. Inside your Yetti, the greatest 12vdc current draw will be your furnace, 35,000 BTU suburban draw 9 amps. Fishing electronics (FL-8 205ma, FL-28 275 ma, camera 300ma, 12v TV 480ma) 1000ma = 1Amp. Use LED lights, the draw about 20% current compared to iridescent lights.If you decide to use a 12vdc to 120vac converter to charge your auger batteries, I suggest you direct connect the converter to your battery with wire and clamps provided.

If all you're running are lights and the furnace, a 15A circuit would be more than adequate, which would be 14ga. The wire lengths involved are minimal so voltage drop should not be a concern.

This all you should need. I used similar wire in my house and it has been fine for five years now

12 volt converters seem to short and cause way more problems, and fires, than they are ever worth. Then trying to diagnose the problem almost requires you to start all over. Another good reason for a wall mount direct vent furnace that doesn’t require a fan to stay heating. Why split hairs between 12 ga. and 14? Cover yourself if you do it.

Can I assume that you are wiring all of this into some sort of power converter vs. directly to a battery?  Either way, I am hoping that you meant to say 12VDC circuits. I would have a dedicated circuit for the furnace, all the lights can run on one, and I went as far as to wire each of my cigarette lighters separately. use a fuse block and a buss bar if not going through some sort of PD or WFCO power converter. 10 ga should be ran from the battery to the distribution source with the assumption that it is a short distance (<4'). If you are buying the rolls of stranded wire from amazon or ebay, I suggest going one size bigger.... If the calculator says 16ga is ok, go 14 and so on. The wire seems to be a little on the light side..... maybe it shrinks on the boat ride over :). Check out the link that Papa posted for the calcuator, it looks spot on. Lots of people don't account for total distance (up, down, and around). I wouldn't mess w/ the sheathed. Are you running the wires in the walls or? .

15 amp for 14 ga is for 110 vac circuits.   10 feet of 14 ga will drop 1/4 volt with 10 amps.

Oh yes, I was thinking 120vac. Sorry.

It still drops the quarter volt per 10 feet (don't forget the neutral return doubles it.) but it doesn't matter as much at 110.

you don't want to used copper tinned aluminum wire. Use Oxygen free copper or 100% copper. the aluminum will corrode away and just leave white powder. also they can not carry as much current as pure copper.
