Electrically intelligent tree
Every drop is checked against the real topology: service type, overcurrent protection, legs and neutral carry downstream automatically.

Panels that know their own wiring.
A browser-based panel designer built on a real electrical topology instead of loose shapes. Drop a breaker and it inherits the service, legs and grounding — or gets rejected with the NEC article that says why.

PANEL DESIGNER — EDITOR
Features
Built for panel shops
A topology-aware editor that treats every device as an electrical object, not just a shape on a canvas.
Live NEC validation
Missing GFCI, unprotected receptacle circuit, breaker larger than the conductor allows — errors cite the article (210.8, 210.12, 240.4(D)) as you draw.

US services done right
120/240 V split-phase, 208Y/120, 480Y/277 and 240 V delta with high-leg awareness, leg balancing and correct black/red/blue, white and green wiring.

Smart terminals
Terminal blocks adapt to their feeder — poles, neutral, ground or 24 V DC +/− — and number themselves as -X1:1, -X1:2 per strip.

Your own components
A device library with terminal-level editing, ratings from real breakers and shared parts managed by your admin.

Workflow
From service entrance to submittal
- 01
Start at the service
Pick 120/240 V, 208Y/120 or 480Y/277, set project data, then drop the main breaker.
- 02
Build the branches
Drag breakers, GFCI/AFCI devices, power supplies, meters and loads onto panels or straight onto a device.
- 03
Let it check itself
NEC validation runs continuously; terminals and device tags renumber on their own.
- 04
Export
BOM as CSV or Excel with vendor pricing, plus an ANSI/IEEE or IEC 60617 schematic PDF.
Exports
Exports that leave the screen
Assign real products and vendors to your virtual devices, then generate a purchasable parts list — grouped by identical items, with order codes, pricing and a project total. The schematic export is drawn from the model as vectors, one-line or full three-line, on framed ANSI sheets with a title block.
- ✓BOM as CSV (UTF-8) and formatted Excel with SUM totals
- ✓Schematic PDF in ANSI/IEEE or IEC 60617 symbols
- ✓Three-line diagrams with each ungrounded conductor, neutral and ground drawn separately
- ✓Terminal list and BOM sheets appended to the drawing
