Cable Ampacity Calculator

Back to Tools

This tool calculates the current-carrying capacity (ampacity) of electrical cables based on recognized international standards. It considers various factors such as conductor material, insulation type, installation method, ambient temperature, and grouping effects to provide a corrected ampacity value. Additionally, it provides estimates for **Voltage Drop** and **Short-Circuit Current Withstand**, crucial for comprehensive cable sizing and protection in industrial systems. The calculation adheres to principles outlined in **IEC 60364-5-52 (Low-voltage electrical installations - Part 5-52: Selection and erection of electrical equipment - Wiring systems)** and **NEC (NFPA 70) (National Electrical Code)**, ensuring compliance with industry best practices.
