Executive Overview
Electrical Panels Manager (EPM), published by BIM_OS, is an add-in for Autodesk Revit aimed at electrical engineers, BIM engineers, coordinators, and model authors. It centralizes electrical-panel data editing, automates recurring panel naming and rating tasks, sizes feeder cables using IEC-based methods, performs voltage-drop and short-circuit studies, and exports engineering reports without requiring the user to leave Revit. The add-in is designed to replace repetitive schedule reading and parameter entry with a single interface that reads model data, calculates results, and writes approved values back to Revit.
Panel Discovery and Data Management
- Automatic panel discovery: Current product descriptions state that EPM can detect panels in the active 2D or 3D view and can switch to whole-project scanning, reducing the need for manual selection.
- Centralized property editing: The interface exposes critical properties such as panel name, location, mains or bus rating, circuit-breaker rating, short-circuit rating, enclosure type, number of slots or maximum breakers, and comments.
- Direct model updates: EPM reads Revit’s electrical parameters and writes edits back to the panel elements in a single transaction.
- Batch processing: Multi-panel selection supports consistent edits and calculations over several panels rather than one element at a time.
- Panel visualization: A Show Panel function highlights or isolates the selected panel in an appropriate view, helping users locate equipment while reviewing tabular information.
- Standardized naming: Auto-naming uses user-defined prefixes, reference codes, separators, start indices, and increments. Panels can be grouped by level, zone, or location reference to align identifiers with project conventions.
Automated Ratings and Connected-Load Workflow
The Auto Calculate or Auto Assign workflow reads connected loads from Revit and uses them to propose mains and circuit-breaker ratings. Marketplace material describes an 80% design-current rule associated with IEC 60364-4-43. This can accelerate initial sizing and improve consistency across a large panel population, but the quality of the result depends on accurate Revit circuiting, load classifications, demand assumptions, supply-system data, and parameter mapping. Calculated ratings should therefore be treated as engineering outputs requiring review rather than unquestioned metadata updates.
