Enables you to review all the acceptable reference cables and parallel combinations defined in the Reference Data Explorer that can be used for the specified load and electrical parameters, and to select from the list a single cable or an assembly of parallel cables. Only those cables that meet or exceed all the sizing criteria appear in the list.

When sizing cables, the software filters out from the Cable-Sizing Matrix all the reference cables whose insulation voltage rating is smaller than the rated voltage of the current cable.

Comment

Indicates whether the suggested cable in the list exactly meets the sizing data criteria or exceeds the needed size as shown by the values: Recommended or Oversized.

Conductor Size

Shows the conductor cross-section area for each cable that meets the sizing criteria.

Number of Cables

Indicates the number of parallel cables for all appropriate recommended or oversized cables that meet the sizing criteria, up to a maximum determined by the values of the minimum cross-section area and maximum number of parallel cables as specified in the Options Manager.

Reference Cable Item Tag

Indicates the name of the associated reference cable.

Description

Displays the reference cable description.

Basic Ampacity in Air

Indicates the basic ampacity in air value.

Basic Ampacity in Ground

Indicates the basic ampacity in ground value.

Maximum Cable Length

Indicates the maximum allowed length of cable of the recommended cross-section that meets the voltage drop requirements.

Required Area (cmils

This column appears only if you select the Use short circuit cable sizing check box and enter short circuit sizing data. It indicates the minimum required conductor cross-section area in cmils needed to meet the short circuit criteria that you specify.

Export To Excel

Creates an Excel spreadsheet that contains the data in the current matrix.
