AC43-13V requires some interpretation and it certainly doesn't tell
anyone how much current your T/B uses. However, it's the Bible. You will
find table 11-3 is most useful. The AC can be downloaded from
http://rgl.faa.gov/Regulatory_and_Guidance_Library/rgAdvisoryCircular.ns
f/key/AC%2043.13-1B

Mike, going to that link does give you access to the entire 43.13-1B as a handy .PDF
as a single file but it says on the page "This AC has been Cancelled." and directs you
to the search page. I did that and I found this results page;

<http://rgl.faa.gov/Regulatory_and_Guidance_Library/rgAdvisoryCircular.nsf/MainFrame?OpenFrameSet>

I then selected this page;

http://rgl.faa.gov/Regulatory_and_Guidance_Library/rgAdvisoryCircular.nsf/0/99C827DB9BAAC81B86256B4500596C4E?OpenDocument&Highlight=43.13>

Which claims to be the replacement. However, you now have to d/l 14 documents to get
it all. So, maybe just using the 1998 version (now obsolete) which is:

<http://rgl.faa.gov/Regulatory_and_Guidance_Library/rgAdvisoryCircular.nsf/8ce3f88c034ae31a85256981007848e7/ccfe0d58d41d2c8086256a55006c6b67/$FILE/AC43.13-1b.pdf>

is good enough since you get it all in a single file.

because a CB is meant to protect the wire, not the equipment. If the
equipment is going to smoke, a CB won't stop it.)

Well said Mike. Same rule applies to your house too. Breaker and fuses aresized to
protect the wiring which is concealed.

It looks like they still use the same table notation in Chap 11.

<http://rgl.faa.gov/Regulatory_and_Guidance_Library/rgAdvisoryCircular.nsf/0/99c827db9baac81b86256b4500596c4e/$FILE/Chapter%2011.pdf>

Which is 125 pages long. Table 11-3 is on page 11-15 and shows for 20 ga wire you need
a 7.5 amp breaker and for 22 ga wire you need a 5 amp breaker and for both wire sizes
a 5 amp fuse is the one. That's bigger than what you stated.

I'm laying out my wiring now and I'm not very confident that I'm not making mistakes.
I sure don't like the idea that the master contactor has to draw current to stay on.
Seem like some kind of over-centering spring switch could be utilized so it stays on
or off without drawing power would be a better choice since I really have to conserve
power.

It also seems ridiculous the cost of some of the stuff like the Whelen strobes.But
that is the subject for another post.

What have we learned in 2,063 years??

"The budget should be balanced, the Treasury should be refilled, public debt
should be reduced, the arrogance of officialdom should be tempered and
controlled, and the assistance to foreign lands should be curtailed lest Rome
become bankrupt. People must again learn to work, instead of living on public
assistance."
-- Cicero, ca. 55 BC

So, evidently nothing..

"The problem with socialism is that you eventually run out of other people's money."
~~Margaret Thatcher~~

"Maybe we have it all backwards. Here's the basic story President Obama
wants to tell. The last eight years were an economic disaster because
President Bush and the Republicans ignored necessary government
regulations and 'investments.' The economic crisis has discredited
'market fundamentalism,' as some liberals call it. Now, thanks to
Bush's hands-off approach to the economy, Obama has no choice but to
get government much more involved. ... Indeed, Obama doesn't feel
compelled to merely remedy the mistakes of his predecessor; he believes
it is vital that we renew the New Deal-style economic policies we
strayed from when Ronald Reagan was elected. ... What if they're
looking at the economy through the wrong end of the telescope? For
starters, Bush was hardly a laissez-faire president who ignored Obama's
oft-stated domestic priorities. Sure, Bush was more laissez-faire than
Obama. But that's not a very high bar. Education spending under Bush
rose 58 percent faster than inflation. Medicare spending, thanks
largely to Bush's prescription drug benefit (the largest expansion in
entitlements since the Great Society), went up 51 percent during the
Bush years. Spending on health research and regulation rose 55 percent.
Spending on highways and mass transit went up by 22 percent. Maybe
that's too little in Obama's eyes, but it hardly validates Obama's
fictions about the last eight years."
-- National Review Editor Jonah Goldberg

"The fact is, we'll never build a lasting economic recovery by going
deeper into debt at a faster rate than we ever have before."
--Ronald Reagan

"When a business or an individual spends more than it makes, it goes
bankrupt. When government does it, it sends you the bill. And when
government does it for 40 years, the bill comes in two ways: higher
taxes and inflation. Make no mistake about it, inflation is a tax and
not by accident."
-- Ronald Reagan

Government's view of the economy could be summed up in a few short
phrases: If it moves, tax it. If it keeps moving, regulate it. And
if it stops moving, subsidize it.
-- Ronald Reagan (1986)
