40 Ft BB All Americanc RE, Pre ordering wire...

[jfmusic@me.com]

For those that have done the work... how much of each of the gauges would you pre-order as a rough idea to start. 100ft?200 250?

What number and length for Battery to the inverter, from inverter to battery?

What will cover all of the 12v LEDS, switches, etc thickness? Length?
I would just assume go with the heavier gauge and use it for all of it rather than 3 or for different thicknesses.

Thanks in advance.

It's hard to know without an exact list of things you are adding and where they are. Every bus is different. I have 800ft of sheathed 16g duplex as I got it dirt cheap. I have 400ft of 14g duplex sheathed. And I have 400ft of 12g duplex sheathed.


I bought 100ft of 10g duplex as well.


I bought this all because it was like 90% off and if it don't use it on the bus, I'll use it on a number of other projects.


If I didnt buy it all that cheap, I would've bought it as I did my wiring, what I needed. 14g is probably good for fans and lights and other small 12v accessories.



Make sure you get 100% copper and not the copper clad aluminum (cca) whatever you get.

I shopped around on Amazon. Purchased 700 feet 14 gauge for $75 Canadian back in February. Have lots left over. Its $135 now though. 7 rolls of different colors at 100 foot rolls. Full copper wire.

I also purchased 18 gauge sheathed wire on Amazon too for my LED wiring. I believe it was outdoor rated speaker wire but works the same. Had a durable black jacket. Also full copper. LED lights dont care if its for speakers. I used the same product to run my LED trailer light wiring on a full flat deck trailer I built. Ran it through steel box frame. Zero problems so far and that was 5 years ago.

Can you explain for me sheathed? Is that the same as shielded?

[fo4imtippin]

Sheathed is just an extra protective coating around the wire.. The below example has 2Copper wire strands, with each having a red or black insulation around it. Then the 2 wires have a white insulation around that.

The below is unsheathed.

Shielded can be a term for having a foil layer wrapped around wires for the purpose of preserving a signal for something like a radio, tv, or ethernet cable.

Checked my history and correct as other member said.

To correct myself I had used 16 gauge and this stuff was fire rated.

What gauge did you use for the AC? 12 or 14 Gauge Sheathed?

[Omnibot2000]

All my 120 volt wiring I ran 12 gauge just because I had left over wiring laying around when I rewired my house.

My R/V A/C roof unit had 12 gauge when I pulled it. I ran new 12 gauge to it. On seperate 20 amp breaker. To control it with the thermostat it had 18 if not 20 gauge. I just ran the 14 gauge wire I had with the rolls I purchased so I could color code it. I kept and documented all my wiring in a binder for future reference.
