Hypalon Cable [RE-wrenches]

[Bill Brooks]

Joel,

I was using interconnects as an example. Of course they are not the same
environment. You should share your results with manufacturers on
interconnects. Do you have some photos of the failures and corrosion you
speak of. Sounds like very important information for the industry. Just
because something has a listing does not guarantee that it will last
forever. As long as it fails safe, everybody but the owner and manufacturer
are happy.

Here is a testimonial I just received from a colleague on welding cable:

"When I was installing new batteries in my system
a few months ago, I found a 1-foot piece of unlisted Excellene
welding cable that had the insulation cracked all the way through in
numerous places.  This cable was being operated within NEC ampacity
guidelines (not the overinflated welding cable current ratings), and
was no more than 11 years old-I think."

This is not good news, and it also does not prove anything. Bottom line is
that it has to pass appropriate listing tests. The NEC Code Making Panels
will not accept it any other way. Every installer and manufacturer then have
to make their own decisions on what they think will provide the best
long-term performance within the realm of listed equipment and supplies.
That's the world of electrical inspections that the grid-connected market
lives in and many off-grid markets now live in.

Bill.

Bill,

Battery and module interconnects are in different environments. Since you
brought it up, USE-2 wire and MC connectors for module interconnects have
only
been in use since 1990. So far connector contacts have corroded,
