Tools
Deterministic engineering tools
Every figure here comes from a pure, unit-tested engine — never the language model. Run them directly, or drop a spec into the Design Pack and we'll route it to the right tool and pre-fill your inputs.

Drop a spec, load list or design pack and the assistant suggests the right tools and pre-fills them.
Load schedule
AvailableConnected and diversified loads → kVA, full-load current and a spare-capacity design current.
Open Load schedule →Cable sizing & volt drop
AvailableSmallest standard conductor CSA that stays within your voltage-drop limit, from first-principles resistance.
Open Cable sizing & volt drop →Fault level & discrimination
AvailablePreliminary prospective three-phase short-circuit current from the transformer source (IEC 60909, simplified).
Open Fault level & discrimination →Block cable diagram
AvailableGenerate a preliminary block cable diagram (downloadable SVG) from a system description. Control schematics and AutoCAD export on the roadmap.
Open Block cable diagram →Single-line diagram
AvailableGenerate a preliminary single-line diagram (downloadable SVG) from a board description — supply, main device and outgoing ways. AutoCAD export on the roadmap.
Open Single-line diagram →On the roadmap
BOM & component selection
On the roadmapStructured bill of materials with ratings and part numbers from an approved component library.
Compliance checklist
On the roadmapInternally-authored BS 7671 / IEC alignment checklist — a prompt for the engineer, not a substitute for design verification.
Preliminary and unverified. These tools produce reproducible first-pass figures from the inputs you give. A competent engineer confirms the assumptions and the final design against BS 7671 and the relevant IEC standards before anything is issued.
