Cable Ampacity Software - IEC Standard

The IEC 60502 standard* applies to extruded insulation power cables rated from  1 kV to 30 kV.

The IEC 60364-5-52 standard* applies to low voltage cables rated less than 1 kV. This standard applies to both underground and aboveground applications.

The cable ampacity calculation module derates the cable ampacity based on the parameters listed here below.

Cable Raceway Installations

The ampacity calculation program handles both aboveground (A/G) and underground (U/G in duct and buried) installations.

  • A/G Conduit (in thermally insulated wall, attached to wall, unventilated channel, ventilated channel in floor, or masonry)
  • A/G Trays (perforated or imperforated)
  • Air Drop (suspended or on insulators)
  • Architrave/Window Frame
  • Brackets
  • Building Voids (in building, cable ducting, or ceiling/suspended floor)
  • Channel (open or ventilated)
  • Embedded Direct (in moldings or masonry with or without mechanical protection)
  • Ladder
  • Masonry (in cable ducting)
  • Open and Clipped Direct (on wall or under ceiling)
  • Trunking (on wall, suspended, skirting trunking, flush floor, or embedded)
  • U/G Buried (in conduit)
  • U/G Duct (in ground)
  • Wire Mesh

 

Temperature Correction

The cable ampacity calculator is the perfect software tool for computing the derated ampacity based on the ambient and conductor temperatures. In addition, the user can either select the base temperature provided by the manufacturer or the operating temperature of the cable.

  • Base Ambient Temperature
  • Base Conductor Temperature
  • Operating Ambient Temperature
  • Operating Conductor Temperature

 

Soil Resistivity Correction

The soil resistivity is an important thermal parameter for actual underground installations. ETAP, as a cable thermal analysis application, allows you to consider the following:

  • Base Soil Resistivity
  • Operating Soil Resistivity

 

Cable Layout in Tray

ETAP’s cable ampacity simulation module derates the cable ampacity based on the following cable layouts:

  • Conduit External Diameter and Channel Depth
  • Spacing from Wooden Wall (based on cable overall diameter)
  • Flat layout - Touching
  • Trefoil layout
  • Horizontal layout – Touching
  • Horizontal layout - Spaced
  • Vertical layout – Touching
  • Vertical layout - Spaced
  • Number of Trays
  • Circuit Clearance

Grouping Factors

The ampacity simulation program for aboveground (trays, air drop, and more) and underground (in duct and direct buried) derates the cable ampacity based on:

  • Number of circuits as limited based on the standard

 

Cable Ampacity IEC Standard Allowable Ampacity Alert

Alert for Allowable Ampacity

ETAP, as a cable ampacity calculation software, provides alerts to the user when a critical situation occurs such as overloading. A critical situation may deteriorate the cable and tremendously reduce its lifetime. The alerts in ETAP can be based on the options listed below.
