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.
