Learn how to use CableHero tools effectively with our step-by-step guides and frequently asked questions.
Calculate cable sizes based on AS/NZS 3008.1.1 standards with automatic derating factors
Start by creating a new project or selecting an existing one from your dashboard. Projects help you organize related calculations together.
Input your load details including current (Amps), voltage, number of phases, power factor, and circuit length. Select the cable type and installation method.
Set up derating factors for ambient temperature, soil thermal resistivity, depth of laying, and cable grouping. The system automatically calculates the combined derating factor.
View the recommended cable size, voltage drop percentage, and fault loop impedance. The system checks compliance with AS/NZS 3008 standards automatically.
Generate a professional PDF report with all calculation details, suitable for submission to authorities or client documentation.
Create professional electrical single line diagrams with our intuitive drag-and-drop editor
From your project, click "New Drawing" to open the SLD editor. Give your drawing a descriptive name for easy identification.
Use the left sidebar to drag and drop components onto the canvas: switchboards, circuit breakers, loads, transformers, generators, and more.
Click on connection points to create cables between components. The system automatically manages cable routing and maintains clean connections.
Select any component to edit its properties in the right panel. Set labels, ratings, protection settings, and cable specifications.
Click the PDF button to generate a professional single line diagram. Choose paper size (A3, A2, A1) and orientation for your export.
Calculate maximum demand per AS/NZS 3000:2018 with automatic diversity factors
Start a new maximum demand calculation from your project. Select the building type (residential, commercial, industrial) to apply appropriate standards.
Add different load types: lighting, power points, cooking appliances, air conditioning, motors, and other equipment. Enter the connected load for each category.
The system automatically applies diversity factors based on AS/NZS 3000. You can override these if needed for specific project requirements.
View the calculated maximum demand, phase balance analysis, and recommended main switch size. Export a detailed report for documentation.
Calculate the right conduit size for your cable installations
Choose the conduit type: PVC, metal (rigid or flexible), or cable tray. Each type has different fill ratio requirements.
Add all cables that will be installed in the conduit. Specify the cable type, size, and quantity for each. The calculator shows the total cross-sectional area.
The system calculates the minimum conduit size required based on the fill ratio limits. View the actual fill percentage and alternative size options.
Calculate solar PV string voltages and configurations for inverter compatibility
Input your solar panel specifications: Voc (open circuit voltage), Vmp (maximum power voltage), temperature coefficients, and number of panels per string.
Set the minimum and maximum ambient temperatures for your installation location. The calculator adjusts voltages based on temperature coefficients.
View the calculated string voltages at different temperatures. Check compatibility with your inverter's MPPT voltage range and maximum input voltage.
