D I-Line Panelboards for DC circuits. We use double-pole phase A &amp; C breakers where Phase A is positive and Phase C is negative.<BR />I have the distribution system set up correctly showing two wires and single phase. L-L is forced to none and L-G is the potential.<BR />In the panel type properties, Number of Phases is set to 1. The number of wires is set to 2. The number of poles is set to 1, as any other number will not allow you to select the distribution system.<BR />How then can I show DC circuits using double-pole breakers as we actually use them?</P> Tue, 12 Oct 2021 14:28:32 GMT afondrenUGA43 2021-10-12T14:28:32Z https://forums.autodesk.com/t5/revit-mep-forum/dc-panelboard-schedule-where-oa-is-positive-and-oc-is-negative/m-p/10683264#M22042 <P>In a real-world application, we use Sq.
