<p>I've got to ask: Are none of the lugs on these Chinese inverters
approved for fine strand cable? I just have not had a problem
with that, but I've mostly used Magnum, Midnite, and Outback
equipment over the years. What were the lugs on the old Trace DC
250 boxes? Were they fine strand rated? They sure were tough to
get 4/0 into, as William mentioned. </p>

<p>William,</p>
<p>If the only reason the ferrule wouldn't fit after using the hex
crimper was the ridge left where the dies meet, you could rotate
the cable 120 degrees and crimp the ferrule again.</p>
<p>I doubt that the indenter crimper will do a decent job with
large ferrules.</p>
<p>I do like your thin piece of copper solution. Not UL approved
but I dare say wrench approved.<br>
