Depends on who built the system.
If a UL integrator builds it, the UR works.
If I build it as joe electrician, then no the UR does not work and
could compromise the code compliance because of it.
At least this is what I was told by a "UL" shop.

Dumb question:
Since the LA is not UL listed, does that void the UL listing on the
entire system? It's my undrstanding that *all* components are
required to be UL listed to make the system such.

Subject: Re: [RE-wrenches] Surge protector update?
Weighing in ...
1)At a recent SMA Inverter Training, we were cautioned that the
Deltas were not
UL listed. Like many of us, I was already well aware of that. What
was
interesting, was the trainer specifically recommending we NOT use
them, for
reasons related to liability.
2)At a different training, by a well respected professional
engineer who
frequently posts here, they were judged to likely be as effective
in preventing
damage as a voodoo doll.
3) If one "ruptured" while someone happened to be standing in front
of
it........
4) Why aren't they UL listed?

I made a service call to a residential PVinstallation several
years ago
that I did not install. The vintage Trace, size I don't recall,
had quit
working. The Delta surge suppressor had actually ruptured along
it's
radial seam, a result I had always heard indicates a surge being
absorbed.
