Section 366.23 of the NEC allows 1000 A / sq. in. of cross sectional area of the conductor. Is that a good rule of thumb, or is there something more specific to battery busing?<br></div><div><br></div><div>Drake <br></div><br><br><blockquote class="atmailquote"><br>----- Original Message -----<br><div id="origionalMessageFromField" style="width:100%;display:inline;background:rgb(228,228,228);"><div style="display:inline;font-weight:bold;">From:</div> glenn.burt@glbcc.com "RE-wrenches" <re-wrenches@lists.re-wrenches.org></div><br><div id="origionalMessageToField" style="display:inline;font-weight:bold;">To:</div>"RE-wrenches" <re-wrenches@lists.re-wrenches.org><br><div id="origionalMessageSentField" style="display:inline;font-weight:bold;">Cc:</div><br><div style="display:inline;font-weight:bold;">Sent:</div>Tue, 30 Apr 2019 20:31:39 -0400<br><div id="origionalMessageSubjectField" style="display:inline;font-weight:bold;">Subject:</div>Re: [RE-wrenches] Bus bar battery jumpers<br><br><br><div class="WordSection1"><p class="MsoNormal">I have always bought the appropriately sized for the anticipated current, copper bar stock from McMaster Carr and cut, drilled and applied heat shrink myself\u2026</p><p></p><p class="MsoNormal"></p><p> </p><p class="MsoNormal">-Glenn</p><p></p><p class="MsoNormal"></p><p> </p><div><div style="border:none;border-top:solid #E1E1E1 1pt;padding:3pt 0in 0in 0in;"><p class="MsoNormal"><b>From:</b> RE-wrenches <re-wrenches-bounces@lists.re-wrenches.org> <b>On Behalf Of </b>Drake<br><b>Sent:</b> Tuesday, April 30, 2019 12:27 PM<br><b>To:</b> RE-wrenches <re-wrenches@lists.re-wrenches.org><br><b>Subject:</b> [RE-wrenches] Bus bar battery jumpers</p><p></p></div></div><p class="MsoNormal"></p><p> </p><p class="MsoNormal" style="margin-bottom:12pt;">Hello Wrenches,<br><br>I am wiring a set of 2 V Concorde batteries for 48 V. Each battery has 2 terminals which will be about 2 1/2 inches away from the terminals they will be wired to. Standard battery jumpers would be ridiculous in this situation. Busbars would be clean and efficient. Concorde doesn't have a solution.<br><br>Does anyone know of a source for busbars?<br><br>Thank you,<br><br>Drake <br><br>Drake Chamberlin<br><i>Athens Electric LLC<br>OH License 44810<br>CO License 3773<br>NABCEP Certified Solar PV <br>740-448-7328<br></i><a href="http://athens-electric.com/">http://athens-electric.com/</a> </p><p></p></div>
