Recommendations regarding Solar Power
We are new to RVing and considering roof-mount Solar system both to keep the batteries topped off but also to run the A/C or uWave. I'm thinking about a 200 Watt system. I am concerned about where...

From my notebook to yours
WIRE SIZES !!!
I have used this in the making of test fixtures for about 40 years and acquired it before I had ever heard of or worked for ITT-Gilfillan.
I hope this helps you out.

Current Carrying Capabilities of Wire
Gilfillan Standard
Max Current Circ. Mils Resistance in
AWG in Amperes per Ampere Ohms/1000 ft @ 25 deg C
26 1.4 180 42.9
24 2.0 200 26.8
22 2.5 255 16.7
20 3.7 275 10.6
18 5.0 325 6.57
16 6.5 370 4.85
14 8.5 450 3.05
12 11.5 530 1.92
10 16.5 570 1.24
8 23.0 730 0.726
6 30.0 895 0.444
NOTES: These current ratings are based on 50% of the maximum allowable under
Specification MIL-W-5088A for wires and cables in bundles of 15 or more
carrying no more than 20 percent of the total carrying capacity of the bundle.
Frequently the maximum allowable IR drop (not the current capablility)
will determine the wire gauge.
This is actually a fairly conservative guide. Depending on circumstances you could go up or down on the wire size.

PS I see the site has compressed the lines. If I could attach an excel file it would be easier to read.
