[Bob Ellison, Alternative Energy Systems]

I understand that Delta has lost their UL listing on their suppressors
recently  and are scrambling to get it back, if they can.

Also welding cable will never be listed for use on anything but welders. I
don't like it either.

Also the next version of the code will remove the UL listing from the Mod
sine inverters.

So much for the news,
Bob

Funny, I just spoke with Kim at Transtector this morning, first time. A
client had requested DC arrestors with a LED "working OK" indicator, and
Transtector makes them. Great, but she quoted $469 each, list. Aren't
equivalent Polyphaser about $200?
We have long used Delta, but described it to clients as "basic protection,
widely and generally accepted in the RE industry, but not very
sophisticated. Please see a lightning specialist for better, as this is not
our specialty."
