Need electrical advise

We have an Airhead Composting Toilet and we've been venting it via a solar powered vent fan, which has conked out. So, I've ordered the vent fan that came with the toilet originally, can't find mine...any way...I need to attach wires for about a 12 foot run from where the fan is to our house battery, which is an Interstate....my questions:

What guage wire should I purchase, for a 12 ft run?

And, I guess I'll just put a connector on the end of the wire and put it on the post of the battery?

Is that it?

Thanks oodles!!

Re: Need electrical advise

I think I read in the Marine wire code that no wire less then 14ga should be used on boats. There should be some kind of amp rating label on the fan but I guess it would be less then 10 amps

Re: Need electrical advise

First off, you really should have a fuse or a breaker on any line. As far as what size wire or fuse, it depends upon amperage carried. Look in the head's documentation for that information. Here's a chart to determine wire size once you know the amp amount: http://www.engineeringtoolbox.com/am...uge-d_730.html

Re: Need electrical advise

The fan draws .06 amp. So it looks like I should get a 16 gauge wire?

No, a 14 gauge? Because it says to calculate the length from the source to the battery and then back again to the source?

Yes. That's correct. You must calculate to and back so 14 gu. is correct. You can put a fuse in an in-line holder or add a breaker that acts as a switch. Otherwise it's running all the time (unless switched at the fan).

Re: Need electrical advise

The fan needs to run all of the time, 24/7....so do I still need the fuse?

Thank you so much for you help! And the chart. I'll remeasure my distance to make sure I have the correct gauge.

Re: Need electrical advise

Yes, you always need a fuse in the event of a short in the wire. You would otherwise risk a fire which would ruin your day!

Re: Need electrical advise

No, we do not want a fire!

Now I have to learn how to install a fuse. Yikes!!

Can I get a fuse, and an in-line holder, and the 14 gauge wire, all at Lowe's?

It's best to get it at a marine store as it will be tinned for the damp environment. If not available, get one at an auto parts store or even Walmart in the auto department. You will need to have some butt connectors and an electrical crimping tool. The in-line fuse holder is simply a tube that separates and holds a glass fuse. The holder has 2 wires (extending from each end). Install the holder in a convenient spot and put it on the positive side. The positive wire color can be any color but black. The negative should be black. If your batteries have studs with wing nuts get ring connectors that have the size of the stud (probably 1/4") and the wire gauge (14) and crimp them on the the ends so you can neatly attach to the battery. It's very easy tho do, you might get a couple wrong but chalk it up to practice.

Good luck!

Re: Need electrical advise

Thank you! I had forgotten about the tinned part, I had discussed this with someone else and they mentioned that. I've made a screen shot of your advise so I can follow it correctly. I'll probably go to the marine works place at our marina and see if they can set me up with everything.

Thank you again!!
