I am to the point of needing to run a battery cable forward to the firewall. I am thinking of  

#2 welding cable. I do not have the engine yet, so can someone give me an estimate of  

how long of a cable I need from the Battery to the starter?   

Also what type and size of cable are people using? and where did you get it?   

Thanks in advance...

Here the stuff. I need to check my invoices but I orderred extra as I ran 

dual cables and I am sure I will be cutting the extra off.

This stuff is Da Kin. Light and it makes relatively tight curves.

I just bought the Vans RV-10 wiring kit.  If you would like, I could get you the wire number and you can just order that wire pre-made.

Actually, the wire is normally run from the battery contactor to the starter contactor which is located on the upper left forward side of the firewall.  Another wire is run from the other large terminal on the starter contactor to the starter.  Not sure what the length is – kind of depends on the exact routing under the baggage area and rear seats, but if you’re wiring the cabin section of the fuselage you’ve got everything you need for that wire run.

John;



My understanding of aluminum wire is the problem of fatigue and 

breakage.  Copper is much more flexible (not quite the right mechanical 

term "metal fatigue"). .  Also, if you look at the table, for that 

length of wire, you may only save 1-2 lbs.  Personally, I know where I 

can shave off 10 -20 lbs of flying weight.

Why not just use Mil Spec Tefzel insulated #2 aircraft grade tin plated copper wire?  The same as in certified ships.  What make this CCA stuff better than that--at $6.75 per foot?Compare that with $2.94 per foot from Teminal Town. (TZ-02 - MS-22759/16-02)http://terminaltown.com/Pages/Page20.html20 feet should do.

If one uses it properly aluminum wire is fine for aircraft.  In fact I am just looking at some long aluminum busbars for an aircraft application.  They do save some weight.  The one think that I was not happy about is that one needs a larger diameter aluminum wire for the same resistance as a copper one and my conduits were pretty full allready.  Didn't want to drill more holes to fit another conduit.

Piper installed aluminum cable in many of the cherokee's, and adding a coating of copper does not increase the conductivity of the cable significantly.  Over time the aluminum cable eat a lot of the battery capacity in a "long" distance...say as compared to battery connected closer to the starter.  It takes capacity from the battery more than copper would and over time the aluminum is less effectent.  So long term you'll need more "juice" and wear out battery's maybe a little more.  How much weight are you saving vs. lost capacity?  Many Piper and other certified aircraft have changed to copper cable via STC's such a Bolger.

How about a couple of measurements on the lengths of all #2 wires?  That would be very helpful.

The problem is not the aluminum cable per se, but the termination of those aluminum cables with tined copper lugs without some type of anti oxidant.  My Cessna Cardinal has an aluminum battery cable that is functioning just fine because Cessna, unlike Piper, terminated the ends correctly by using an anti oxidant paste.  When someone re-terminates an aluminum cable without using the paste, corrosion builds up between the aluminum and the copper terminator causing high resistance. 

While the aluminum cable in my Cardinal is performing just fine, I will go with the a standard tinned copper cable in the -10.Williamhttp://wcurtis.nerv10.com/X-Rcpt-To: <wcurtis(at)nerv10.com>Piper installed aluminum cable in many of the cherokee's, and adding a coating of copper does not increase the conductivity of the cable significantly.

Yep, that’s pretty much the whole goal to copper cladding the AL wire.  This is the same reason so many house fires were started back when they started using aluminum wire.  It wasn’t that the aluminum wire wasn’t up to it, it was that they didn’t know they need to change their methods for terminating it to avoid the corrosion and subsequent overheating.  Copper clad allows you to go about it like it is any other copper wire.  I gave it a serious look but unless I was building a super stretched RV-10, the weight savings didn’t make financial sense to me over good ole #2 welding cable.

Thanks for everyones input. I would like to know what this paste is that 

needs to be placed between the lug and the aluminum cooper wire of the fat 

wire.



As for the aluminum wire being brittle and not being able to handle fatique, 

I question where all the fatigue will be coming from in my installation of 

the cable.



This fat wire is quite interesting in that as you bend it one can feel all 

the individual wires moving over one another. It is quite flexible.  As I 

said, it is also quite light. I have used #2 welding cable on an automobile 

starter motor which I made into a high launch winch for launching Large RC 

gliders. That stuff is quite inflexible and is very, much, more, heavy.



Being that I am installing dual batteries with the Eggenfellner engine, I am 

installing twice the amount of battery cable. Weight was a huge concern.



Please tell me about the paste which will keep my battery cable for catching 

on fire like the light British destroyer did in the Faulklin Island 

conflict. I wouldn't want my plane to fall out of the sky.



Here are some cable routing pics showing all the support to the cable. Huge 

rubber grommet are used in stead of nylon snap bushings. Concern for 

chaffing was very much considered.



Now to some unanswerred question about Radio and mic jacks.

In telecom we use No-Ox made by Sanchem:



http://www.sanchem.com/ox.html



It's applied to all electrical terminations using a mechanical means of 

connection.  Apply sparingly.  If you can see it, you've applied too much!

One of the commonly used products (and I think pretty good) is called Alox.

When I worked as an electrician, we used aluminum cables from the street disconnect to the house panel and at the terminal on each side used Alox, applied liberally.  There are other brands as well that perform the same funtion.  It is pretty commonly available at electrical supply houses - describe what you're after and they should have it.
