VERIFIED · RADIAL
32 wires · every wire has 2 ends
Each feeder is explicit. MCC-07 resolves to feeder 4 without guessing.
INTERACTIVE PROOF · STRUCTURED ECAD
The drawing is one view. Switch states, live paths, isolation points, and export data come from the same topology.
Open any switch. The drawing recalculates immediately.
WHY A MODEL
The same 33 components can describe two different systems. One integer exposes the difference.
“480 V, 3 phase … 6 × 1200 A fused disconnects … each will feed 2 × 600 A disconnects … each will feed MCCs.”
VERIFIED · RADIAL
Each feeder is explicit. MCC-07 resolves to feeder 4 without guessing.
REJECTED · SHARED BUS
The model declares “radial,” so a multi-terminal bus is a machine-checkable violation.
THREE QUERIES · ONE MODEL
LIVE
Open feeder 4. Two MCCs and their downstream disconnects lose power. The source-side terminal remains live.
LIVE · SAFETY
LOTO procedures are written safety documents. The graph finds every lock point, including reverse-feed paths.
ADAPTERS PLANNED
Stable component IDs and terminal references are the handoff boundary to PLCopen XML, AutomationML, TIA Portal, and CODESYS.
Select a query above. Its result will be computed from the same fixture that renders the drawing.
SCOPE · HONESTLY MARKED
Implemented and planned formats are deliberately separated.
IMPLEMENTED
MODEL-DERIVED
PLANNED
OPEN MEANS SPECIFIC THINGS
Components have stable IDs. Wires connect terminals, not vague boxes. Topology, layout, operating scenarios, and symbols stay separate.
You can inspect the schema and run the same acceptance fixtures used by this page.
