One issue that has been troubling me is the 1 size fits all.
We live and work in many really different environments.
Because of this, what works here might not work there, but just
because it doesn't work there, does not mean
that I shouldn't be able to use it here.
Lets look at the the desert regions vs Hawaii. In the desert rust/
corrosion just isn't a problem so braided wire isn't going to be a
problem.
Vs hawaii where maybe only solid wire, let alone stranded is the only
choice.
So I think that our industry is getting really far down the 1 size
fits all path and i see that being ineffective, expensive, and throws
creativity out the window.
Just my 2 cents.

it sit in a puddle of water for over 20 years. I will say that the
green
oxide coating occurs pretty soon after installation usually in the
first
6 months to 1 year whether its solid wire or braided. Its caused by
the
interaction of the copper with oxygen. It's a non issue as long as
your
contact points are good. You can ohm it out to verify the contacts are
good. 5 ohms or less is a good ground. Want to do more testing? then
it's time to break out the arc welder.

We don't use braided for direct burial. We use it to bond to the
array, run with the PV wires, and switch to regular copper as soon as
we go into conduit at the first J box. We zip tie it together in a
bundle with all the MC cables.

Braid tends to "wick" water, and we have seen it corrode into a
crumbly green mass of copper oxide in a matter of 2-3 years in wet/
damp locations. Probably OK for indoor use, but we prefer to avoid
it completely.
