<font face="Times New Roman,Times,serif">I asked this one last
year and got a few "That's interesting" responses, but nobody </font>actually
came up with an answer. Perhaps it was too obvious.<br>
<br>
I have been looking at Teck 90 waterproof metallic armored cable as
a possibility for DC wire runs. This is the stuff:
<a class="moz-txt-link-freetext" href="http://www.onestopbuy.com/omni-wire-cable/T30804-40643.asp">http://www.onestopbuy.com/omni-wire-cable/T30804-40643.asp</a> It seems
to be roughly the cost of wire and conduit and a lot easier to run.
It looks versatile:<br>
<br>
"Suitable for use in ventilated, non-ventilated and ladder cable
trays, direct earth burial or raceways, and for exposed or concealed
wiring in wet, damp or dry locations. Suitable for use in wet or dry
locations when installed in accordance with the NEC."<br>
<br>
The question is, would this stuff be acceptable code-wise for
metallic-contained interior DC wire runs per 690.31 (E)? You'd think
so, but I'd want to be sure before buying a reel of this stuff.<br>
<br>
Thanks, wrenches!<br>
