You can get (4) #6 THWN-2 in a 3/4" PVC conduit at 40% fill.</div><div class="ydp7b2e1bb9yiv1931548375gmail_default" style="font-family:arial, helvetica, sans-serif;"><br clear="none"></div><div class="ydp7b2e1bb9yiv1931548375gmail_default" style="font-family:arial, helvetica, sans-serif;"><a shape="rect" href="https://www.grainger.com/product/CANTEX-1-x-3-4-PVC-Reducer-4FYK1" rel="nofollow" target="_blank">https://www.grainger.com/product/CANTEX-1-x-3-4-PVC-Reducer-4FYK1</a><br clear="none"></div><div class="ydp7b2e1bb9yiv1931548375gmail_default" style="font-family:arial, helvetica, sans-serif;"><br clear="none"></div><div class="ydp7b2e1bb9yiv1931548375gmail_default" style="font-family:arial, helvetica, sans-serif;">Regardless of the conduit type, you could also just pass through a j-box rather than splicing inside. The 3/4" KO should still be big enough for your #6 inverter output circuit.</div><div class="ydp7b2e1bb9yiv1931548375gmail_default" style="font-family:arial, helvetica, sans-serif;"><br clear="none"></div><div class="ydp7b2e1bb9yiv1931548375gmail_default" style="font-family:arial, helvetica, sans-serif;">Jason Szumlanski</div><div class="ydp7b2e1bb9yiv1931548375gmail_default" style="font-family:arial, helvetica, sans-serif;"><br clear="none"></div><div><div class="ydp7b2e1bb9yiv1931548375gmail_signature" dir="ltr"><div dir="ltr"><div><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><table class="yahoo-compose-table-card" cellspacing="0" cellpadding="0" border="0"><tbody><tr><td colspan="1" rowspan="2"></td><td colspan="1" rowspan="2"><table style="border-left-width:1px;border-left-style:solid;border-left-color:rgb(237,237,237);color:rgb(85,85,85);font-size:13px;padding-left:10px;" class="yahoo-compose-table-card" cellspacing="0" cellpadding="0" border="0"><tbody></tbody></table></td></tr></tbody></table><b></b><div style="text-align:center;"><br clear="none"></div></div></div></div></div></div></div></div></div></div><br clear="none"></div></div><br clear="none"><div class="ydp7b2e1bb9yiv1931548375gmail_quote"><div class="ydp7b2e1bb9yiv1931548375yqt8449213637" id="ydp7b2e1bb9yiv1931548375yqt37917"><div class="ydp7b2e1bb9yiv1931548375gmail_attr" dir="ltr">On Tue, Dec 3, 2019 at 9:05 PM frenergy <<a shape="rect" href="mailto:frenergy@psln.com" rel="nofollow" target="_blank">frenergy@psln.com</a>> wrote:<br clear="none"></div><blockquote class="ydp7b2e1bb9yiv1931548375gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-style:solid;border-left-color:rgb(204,204,204);padding-left:1ex;">

<p>Wrenchers,</p>
<p> This particular install requires 6 Gauge for the AC
output from a few SB7.7......-41 inverters (for voltage drop).
Pretty tight for the 3/4" knock-outs in that inverter. Any harm
in using a step-drill to open it up to a 1" KO? Any experiences
with this? I'm trying to avoid a J-box with a transition to 8
Gauge with 4-14 Polaris connectors.</p>
