Key Features and Capabilities
Low Voltage Electrical Network Design
Automated low-voltage electrical network design from LV/HV supply, to multiple switchboards, loads and capacitor banks.
Outputs calculation reports, equipment schedules and network interactive single-line diagrams.
- Interactive Single-Line Diagrams: Build and visualise custom network diagrams with live editing and AutoCAD® export.
Supply Sizing & Multiple Switchboards: Transformer and generator sizing. Multiple switchboards and final sub-circuits or loads.
Network Voltage Drop and Fault Loop: Automatically sizes cables to meet the network voltage drop limit and calculates the total fault loop.
Fault Level & Maximum Demand Calculations: Performs fault level calculations and upstream maximum demand for switchboards.
Protective Device Coordination and Selection
Perform coordination studies, verify discrimination and choose the right protective devices with confidence.
Time-current curves: Plot time-current curves and check discrimination for cascaded circuit breakers and fuses to match your custom electrical installations.
Huge database of devices: Over 50,000 manufacturer devices. Time-current curves, settings, breaking capacities, part numbers and characteristics are available.
Coordination criteria and Sequence of operation: Coordination criteria ensure standards compliance for current and time-based discrimination.
Generate Commissioning-Ready Reports: Create detailed reports including time-current curves showing discrimination, device details for purchase and settings for commissioning.
Cable Sizing and Maximum Demand Calculations
Easily and instantly selects the minimum safe cable size in full compliance with AS/NZS 3008 and AS/NZS 3000 Standards.
The maximum demand calculator automatically applies the rules for all installation types and balances the loads.
Automatic Cable & Earth Sizing: Automatically selects the minimum compliant active and earth cable sizes. Manually select cable sizes to verify compliance.
Accurate Voltage Drop: Calculate voltage drop and voltage rise for DC, single-phase and three-phase systems.
Automated Maximum Demand: Domestic or living units and non-domestic installations. Automatically applies rules and balances phases.
Fault Loop Impedance Verification: Protective device (MCB, MCCB, ACB or fuse) settings used for calculating earth fault loop impedance.
Compliance Reports and Project Documentation
Create client-ready reports, compliance documentation and cable schedules directly from your electrical design calculations.
Custom-Branded PDF Reports: Generate professional reports containing calculation inputs, results and compliance checks, complete with your company logo.
Standards-Based References: Include table numbers, column references and supporting data from AS/NZS 3008 to improve transparency and verification.
Voltage Rise Compliance Reports: Generate dedicated voltage rise reports for multiple cable runs to support compliance with AS/NZS 4777.1 installation requirements.
Cable Schedules for Project Delivery: Export cable schedules directly to Excel for procurement, construction documentation and project handover.
AI Electrical Calculations
Get standards-compliant cable sizing results through ChatGPT and Claude’s interfaces, backed by the proven Cable Pro Web engine.
- Natural Language Workflow: Describe your project requirements conversationally without entering parameters manually.
- Verified Calculations: Every calculation is produced by the Cable Pro Web engine, delivering results you can trust on real projects.
Standards-Compliant Results: Receive outputs aligned with Australia’s AS/NZS 3008 and AS/NZS 3000 Standards, complete with documented calculation details.
Submission-Ready Reports: Generate professional reports with applied parameters, referenced standards and traceable results.
