Electrical question

This isn't about the electrical system of my Jayco persay, but about a mod I am attempting to do. Help if you can. I am purchasing 2 air circulators that I am going to install on the bunk house ceiling. I am going to cover the wires with wire molding. I would like to go from one wire on each into just one wire total. I plan on installing one on each side of the roof vent facing opposite directions, then going to the back of the bunk house with the power cords. They are .3 amps each btw. Somewhere past the second fan, I want to combine both wires into one and continue from there. I have googled the heck out of this and can not find a thing. Any help appreciated.

What do you mean by "I would like to go from one wire on each into just one wire total."? You can't wire anything with just one wire. Need a supply and return/ground. Maybe I'm not understanding the intent.

Electrical question

Being the fans draw so little amps, why couldn't you run stranded wire like what you would use for a lamp. Then you could solder it and use heat shrink?

Sorry, by wire, I should have said power cord. Basically a lamp cord. Here is a link to the fans. http://www.westsidewholesale.com/hea...0(CR1-0117-06)

That is what I want to do. I just wasn't sure if it was a safe thing to do. Do I have to solder it, or could I use butt plugs that I crimp then heat shrink? Do I use the same size stranded wire, or should I go heavier? Here is a link to the fans. Thanks for your help. http://www.westsidewholesale.com/hea...0(CR1-0117-06)

I would solder them then heat shrink. Less chance of them pulling apart. I work in the auto industry and i never use a butt connector. Everything gets solder or a straight run with no connections to come loose or voltage drop.

My experience with crimped butt connectors is that they are very unreliable. Go with soldering.

if the fans are to feed two seperate areas, switch each one~~~difference in temp needs. Fuse each close to power sourse ~ coming off say a duplex plug fuse right there. Allow enough back side of fans area to draw air. Put fan in an area that it/they can be rotated, make your own center pinned mount if necessary ~ again different strokes for different folks. Put fans out of harms way ~ murphys law. Consider timers or a thermostat inline shut off.

I disagree. I work in the marine industry and done thousands of crimp connectors with no failures. it is dependent on the quality of the connectors, the crimpers and the experise of the person doing the crimp. Learning to crimp is much easier to learn than learning to do a proper solder connection.

Krackeer, if I understand you correctly yes, you can run just one set of wires but you need run pigtails off it at each fan location. You have to run a "parallel" circuit and not a "series" circuit or your second fan may not get enough voltage.
