| Subject: | Re: #2 or #4 AWG? |
Hmm, I find this interesting from a couple fronts. Yes, 4AWG gives us a little
more voltage drop but with two batteries carrying the load (according to both
the OP and for my Z-14 arrangement) that seemed fine. Z-14 diagrams show both
4AWG and 2AWG in the starter circuit. Why both sizes?
Perhaps answering my own question, perhaps the examples shown were postulating
short runs of 4 AWG and a long run from the start contactor to starter?
My plan with a non-conductive airframe, two batteries separated by four feet and
both well aft is 4AWG between the batteries, a Bus-Tie contactor for starting,
and 2AWG for the combined starter circuit. But with a two battery start and
a combined loop (power and ground) for starting of 20 feet, it sounds like weight
for nothing.
Thoughts?
