Hello Bob

I have a wire size question.  I use your 2 bat 2 alt all electric configuation for my Glasair.  I use circuit breakers on a panel on the right side of the panel.  The problem is that the person that helped me wire the airplane ran #4 wire from the firewall pass through and attached to the breaker panel.  These are very stiff ( not welding cable) and put stress on the connections to the breakers.  I would like to terminate the 2 #4 wires on the sidewall on 2 separate studs and from each of these two studs run 2 #10 wire (about 6 to 10 inches)to each end of the strap connecting the hot side of the breakers on each of the two circuits.  I hope this  is clear.  My question is; would 2 #10 wire be sufficient to replace for a short run the #4 wires?

Jim

     I'd really rather you didn't have all this "hardware"

     in the system. How about replacing the 4AWG tefzel with

     a 6AWG welding cable which will be MUCH easier to work

     with and entirely adequate for alternator outputs of

     60A. I'm presuming that your alternator is no larger

     than this. Alternatively, a single chunk of 4AWG welding

     cable would be MUCH preferred.

Hi Bob

Your solution is OK and doable.  I just worry about the weight of the wire on the copper tie strip on the breakers.  I could figure a support for the much more flexible wire.

I am running a pad mount 20 amp and a belt driven 40 amp alternators.  Can you make up the wires with ends if I provide the length and connector sizes?

If you walk into your local welding supply shop & tell 'em you need x 

feet of #6 and y crimp-on lugs for the wire with z stud size, then ask 

if they know anyone who might rent you a crimper, odds are good that 

someone at the counter will go get a crimper out of stock & do it for 

you on the spot.
