The description table, XL&R_DESC, contains the labels used on the Wire Size
Lookup
on page 712 dialog box for the conduit or raceway type selection list.
The labels also map to the columns in the data tables.
Data tables
The conductor reactance/AC resistance data tables use the following naming
convention:
■ XL&R - the table name prefix
■ _{type} - the wire metal type such as CU for copper, or AL for aluminum.
■ _{size} - wire size standard such as AWG, or MM2 for metric.
■ _{standard} - optional suffix to relate it to a specific electrical standards
code. For example, an “_NEC” suffix could mean that the data for the table
parallels the National Electrical Code. A suffixed table name is not necessary
unless you plan to set up the electrical standards database to support
multiple standards.
