About this app

Revit users, rejoice! If you've been struggling with electrical calculations, then the Sizing Cable & CB plugin is here to simplify your workflow. This remarkable tool is designed to work seamlessly within Autodesk® Revit®, allowing you to perform a wide range of electrical calculations with ease.

Streamlined Circuit Breaker Sizing

One of the standout features of Sizing Cable & CB is its ability to quickly select the circuit breaker based on the Apparent Current Parameter of each circuit. This takes the guesswork out of circuit breaker selection and ensures that you're using the correct breaker for each circuit. The user-friendly interface allows you to edit the selection manually, giving you full control over the process.

Effortless Cable Sizing

With Sizing Cable & CB, selecting the right cable is a breeze. The plugin takes into account the Apparent Current Parameter, installation method, cable type, and more, according to IEC standards. This ensures that your cables are sized correctly, minimizing the risk of overload or inefficiency. And just like with circuit breakers, you have the option to edit the selection manually, giving you flexibility and control over your electrical design.

Accurate Fault Current and Voltage Drop Calculation

Calculating fault current and voltage drop is crucial for ensuring the safety and efficiency of your electrical system. Sizing Cable & CB simplifies these calculations by automatically determining the available fault current at each panel and calculating voltage drop on circuits. With this information at your fingertips, you can make informed decisions and optimize your electrical design.

Efficient Transformer Selection

When it comes to transformer selection, Sizing Cable & CB has got you covered. The plugin automatically selects the transformer based on the apparent load with a spare factor. This intelligent feature saves you time and effort, allowing you to focus on other aspects of your design. Say goodbye to tedious manual calculations and let Sizing Cable & CB handle the transformer selection for you.

Optimized Circuit Length Calculation

Sizing Cable & CB takes the guesswork out of determining the maximum circuit length. By calculating this parameter for each circuit, the plugin enables you to compare the wire length and place equipment conformably. This optimization feature ensures that your electrical design is efficient and meets your project's requirements.
