Interesting... <br><br>
What if the array is ground mount? I prefer not to have metallic
conduit underground. Fortunately, for off-grid we often have a
combiner on the rack that qualifies for a disconnecting means.<br><br>
Also, off-grid Voc is on the order of 100 volts, as opposed to 400 to
600.<br><br>

It is interesting that the 2008 code also has the
"utility-interactive" typo. None the less, it is
appropriate to put photovoltaic circuits in metal conduit for off grid
systems. The risk to fire fighters is nearly the same in both
cases.<br><br>
