Thanks Dale,
I was really referring to the fuel pump breaker, didn't make that clear. I
believe Tracy said to go to the higher breaker on this service.
I have not seen as yet any real world wire sizing tables, were did you get
the info for the 30 feet?  This is a more practical footage for aircraft
wiring.  I have  table from powerstream.com giving 18ga. as capable of 16
amp for chassis wiring but 2.3 amp for transmission wiring.  Would aircraft
fall between these or is the transmission closer to what we need?  I don't
like calculating from resistance per K feet and such.  Quick look-up tables
is what I'd prefer if they exist for practical vehicle/aircraft wiring.
Make any sense?
