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 style="caret-color: rgb(0, 0, 0); font-family: Helvetica; font-size: 12px; font-style: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration: none;">Ray <br>Remote Solar</p><div class="moz-cite-prefix" style="caret-color: rgb(0, 0, 0); font-family: Helvetica; font-size: 12px; font-style: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration: none;">On 9/3/2025 12:57 PM, Kent via RE-wrenches wrote:<br></div><blockquote type="cite" cite="mid:50bf396a-4f5b-42bc-9f61-35a89d651dfc@coveoregon.com" style="font-family: Helvetica; font-size: 12px; font-style: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration: none;"><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.
