Hi

On my build I decided to use CCA (Copper Clad Aluminium) wire from perihelion designs.

Info and specs on it can be found at:

I am quite surprised at how much lighter it is. Apparently it is used by the big guys (ie AirBus etc) due to the weight savings.

Cheers

Les

I’ve been flying with this wire since 2007.  1700 hours and not a single issue. And yes, significantly lighter.

What do you estimate the weight savings? Perhaps we would do better to
reduce weight of the front seat occupants by say 5 lbs?

Hi Kelly

What a great idea. Go on a diet and also save weight on the battery cable.

Cheers

Les

I thought the aluminum wires were more susceptible to work hardening and cracking than he copper ones.

Like others, I’m curious as to how many pounds were saved.
Also, since this wire is fatter, did you have to oversize any bushings to get the wire(s) thru?

If you replace 2AWG with "Super 2 CCA" (what I used) from the battery to the firewall, you save about 2 lbs.

I ran the wire up the right side of the fuse, under the door sill, across the panel structure to my GPU plug in front of the left door.  I did have to accommodate the larger size.  I don't recall any specific adverse issues but like any mod it took more effort.
Perihelion lists specs and discusses work hardening, corrosion, etc.  Like I said, my installation has been trouble free for some time.
