Question: Since the Delta lightning arrestors are not UL Listed, do they
threaten the UL compliance of the PV system as a whole?<br>

<p class=MsoNormal>I would think that an ohmmeter set to the 10 Mega-ohm

something on the order of 750 k-ohms (3/4 of a mega-ohm).<br>
<br>
But the system should be tested at a higher voltage, than that available<br>
from a DMM. Apply 240 Vac and measure the RMS current. It should be should<br>
be 0.3 mA or less.<br>
<br>
Finally, these puppies really need to be tested at much higher voltages,<br>
perhaps someone knows how to use that megohmmeter to test? What does the<br>
manu recommend, “if suspect, throw it away and buy a new one”?<br>

What is the best method for testing the integrity of a DC and/or AC<br>
lightning surge arrestor? Specifically, i use the Delta LA units. I
know<br>
they should be replaced if they look Bar-B-Qued, but otherwise...?<br>

use in just about 8 minutes. And it's wireless!"<br>
