Parameter names for circuit quantity on switchboards and panelboards have been improved.
Prior to this enhancement, switchboard schedules had rows reflecting the Max #1 Pole Breakers parameter value. These schedules typically had multiple blank or empty rows when multi-pole circuits were connected to the equipment. As a result, the schedule appeared to reflect available capacity. However, when trying to connect circuits, Revit reported that the equipment was full.
With this improvement, for switchboards (Electrical Equipment with Part Type set to Switchboard), the "Max #1 pole breaker" is replaced with a "Max number of circuits" parameter.
The Max #1 Pole Breakers parameter on panelboards has been renamed to Max Number of Single Pole Breakers.
