Customer Q&A

2 questions already asked

Q
What is the bare wire diameter of 1/0 gauge without outer sheathing? Is the 0.625" with sheathing?
[ Paul  Jun 03, 2019 ]

A
Yes the .625" is the sheathing diameter. Bare wire directly where it exits the sheathing measured about .388" on the piece I measured. With that said, about a half inch past the sheathing, it measured about .525". The individual strands are tinned, there's a bunch of information for that on the web, but the important bit is that it tends to "fluff" out. If you check the AWG wire diameter table on Wikipedia this wire actually falls between double ought and triple out wire diameters. I had difficulty soldering it in the standard 1/0 connector and have been thinking about redoing it with a 2/0 connector. I hope that helps.

the inner wire is 1/2" so with the sheathing yes I'm sure its .625"

What is the ground cable tinned with?

Hey William, the wire is coated with Tin (Sn), the metal, to help prevent corrosion and oxidation.
