What is a single-line diagram
The single-line calculation diagram is the main document of an electrical supply project. It shows: power source, panels, outgoing circuits with breaker ratings, cable cross-sections, and loads. All three phases are shown as one line — hence the name.
In traditional design, the diagram is drawn manually — taking 30-60% of project time.
How GorkyCAD builds it automatically
1. Place electrical objects on the floor plan
What's on the diagram
- Main breaker with rating
- RCD with leakage current
- Group breakers with ratings
- Outgoing circuits with cable type and cross-section
- Calculated loads per group
- Total power
Editing
The diagram can be adjusted: rename groups, reorder breakers. When the plan changes, the diagram updates automatically — no redrawing needed.
Result
Single-line diagram — in 5 minutes instead of 2-4 hours. With automatic recalculation on any changes.
