Cable Ampacity Calculation Software

As a cable ampacity analysis application, ETAP electrical calculation software calculates cable ampacity based on the following standards:

• IEEE* - IEEE Standard 399 - Recommended Practice for Industrial and Commercial Power Systems Analysis
• ICEA* - ICEA P-54-440 - Ampacities of Cables in Open-Top Cable Tray
• NEC* - NFPA 70 - National Electrical Code
• British Standard** - BS 7671 - Requirements for Electrical Installations
• IEC** - IEC 60364-5-52 - Selection and Erection of Electrical Equipment - Wiring Systems

* Module included in ETAP Base Package
** Additional Module - Not included in ETAP Base Package

This cable ampacity analysis program is systematic and simple. For example, for A/G trays, simply enter the tray height, width, and percent fill, the cable ampacity analysis software calculates the derated ampacity based on user specified ambient and conductor operating temperatures.

Types of installation:

A/G Conduit A/G Trays Air Drop – Suspended Architrave Brackets Building Voids

Channel Cleats Embedded Direct Ladder Masonry Open & Clipped Trenches

Trunking U/G Direct Buried U/G Duct Bank Window Frame Wire Mesh

For duct banks, specify the number of rows, columns, ambient temperature, and soil thermals resistivity, ETAP as a cable ampacity calculation software, computes the derated ampacity based on the hottest location not exceeding the maximum operating temperature.
