Thanks Rob, We have been using Unirac for many years and slow to change
(since we have so much of it in inventory). I think with the difficulty
of pv module disconnects now, and good wire management, a barrier is
really a solution looking for a problem. I'll take a look. Thank you
again. Chris

I have mentioned in the past, look into US Solar Mounts, The wire management is
built in!
They have several different styles of mounts and many of them have wire
management built into the frames
Custom-built for each install so you tell him what you're using and what you
need and they will tell you what will work best
Another product that's made in the USA!

I am well aware of all the possibilities of danger in many aspects of life.
This is not a main one in my opinion, and given that there are no good
solutions indicates to me that it is mostly an unsolvable problem unless you
wish to be impractical. All I asked for were products that could provide a
solution. . I have inspected in several states with solar programs that will
not enforce securing electrical enclosures in living spaces that have access to
240 v. I even seen this situation in a children's play room.
I think that is more than a little more serious issue.

I believe strongly that the code requirement to protect PV wires from
unauthorized personnel is justified. Ground mount arrays are essentially
jungle gyms and could attract children to climb. If a 50 pound child
inadvertently swings on a PV cable across a sharp metal edge the insulation
could easily be compromised. The current limited nature of PV means the
current will sink through the short until the short is opened, leaving up to
600 volts at fatal amperage exposed to the touch. Inadequate ground fault
interruption technology does little to prevent the problem.
You cannot legally install a convenience receptacle at any height above
ground with the individual conductors exposed, so why should one be allowed
to install PV with individual conductors readily accessible?
I grant you that shielding PV wiring on a ground mount is a difficult
process. It is very unfortunate that the industry has been allowed to
evolve without developing decent wire management hardware in the process.
If you are not aware of the work we have done on wire management solutions,
you might visit our website where we share all of our ideas. We are giving
away trade secrets, but I feel a moral obligation to help everyone in the
industry deliver a safe product.
Most sincerely,

Thanks all, I don't see a good solution to what I think is a non-existent
problem. I believe that anyone who wants to pull apart dc subarray
conductors is attempting to vandalize. It's not easy to do, and you really
have to be wondering why someone would even try. Why don't we put all
electrical outlets 8 feet off the ground?

Friends:
I looked at the Solarmount web site and I don't think the product
complies-- the wire management leaves leads exposed. It's a nice start,
however.
I was asked by Homepower to do an article on wire management. I was
flattered they'd ask, but I had to decline because there is so few
options off-the-shelf that I can recommend.
