<div class="moz-cite-prefix">200.6 allows 3 continuous white
stripes to identify the grounded conductor on wires smaller than
#6, so All cable's marking would qualify, we just can't field tape
it. (which makes sense: if the white tape falls off, and you're
left with 2 black wires, you're in for trouble...) <br>
Second, we are allowed to tape wires all we want for our own
purposes (like DC polarity, or circuit ID) I love my 3M and Brady
wire label makers. I could even put a label on a white wire that
said: "DC negative, grounded conductor"<br>
We just can't use tape all by itself to identify the grounded
conductor.<br>

striping and marking to any wire you need.

<div>Marco- You should not transition to THHN wire
at all for the DC run. The PV wire is double
insulated for a good reason- the transformerless
inverters are such suckers for a ground fault
that they need the extra protection. That's why
the NEC specifies PV wire. </div>
<div>I recently did an installation like you
wrote, with a transition at the j-box. This
developed an intermittent ground fault when wet,
and when the P1 inverter failed it was deemed
out of warranty. Learn from my mistake-- use PV
wire all the way to the inverter. </div>

</div>
<div>That said, does anyone know where to get 1000
volt PV wire in colors other than red, black,
and white?</div>
<div>It would be nice to color code the positive
runs like is possible with colors of THHN.</div>
<div>I'm thinking of buying spools of white and
spraying plastic paint on them for a striped
color coding.<br>

Hi all,<br>
<br>
We're doing more and more installs with TL
inverters (SMA and P1).<br>
<br>
I'm using double-insulated wire from the array
string to the first<br>
enclosure, as in j-box, and then transitioning
to standard THHN/THWN wire.<br>
