Overview
The Fill Circuits Tool automates one of the most repetitive electrical tasks in Revit: assigning devices to panels and circuits. Select lighting fixtures, receptacles, or equipment, pick a target panel, and the tool creates circuits and distributes the load automatically — respecting phase balance, spare capacity, and circuit-naming rules. Assignment logic follows configurable rules such as room grouping, system type, and maximum devices per circuit, so the result matches your office standards instead of Revit's default behavior. Panel schedules update immediately, and a summary reports any elements that could not be circuited so nothing is silently skipped. For projects with thousands of devices, this turns hours of manual circuit creation into a controlled, reviewable operation that takes minutes.
