The real issue is voltage drop, particularly in a 12 volt system where you may not have a lot of spare volts to play with. I don't think #6 or #8, or their paralleled equivalents, are overkill in such applications.

And while the AC may not draw 40 A continuous, the initial starting surge may get up there.

That's the way, regardless of short or long runs. 73 de Jim, N2EY ************************************** Get a sneak peak of the all-new AOL at http://discover.aol.com/memed/aolcom30tour _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
