ELECTRICAL AND PHYSICAL CHARACTERISTICS OF CLASS B ELECTRICAL CABLES Approved:
k s' l.0 SCOPE 1.1 This Standard provides useful electrical and physical characteristics of Class B electrical cables.
2.0 GENERAL 2.1 The physical characteristics of specific cable types are shown in Table A and Electrical Characteristics of specific cable types are shown in Table B.
All AC Data is based at 60 Hz.
2.2 For round stranded cable, the resistance (R,) at a temperature (t)"C may be obtained from the cable resistance at 90"C (R,o) as follows:
p*, ' 234. 5 + t' p

324.5 e
ww 2.3 The reactances shown on Table B are based on the following i

where D is the spacing between conductors and GMR is the Geometric Mean Radius.
2.4 The insulation and jacket thicknesses and the conductor and insulation shield thicknesses used to calculate "D" for 3/C cables are given in Form 1926, " Standard Specification for Low Voltage (0-2kV) Power and Control Cable Insulated with Ethylene-Propylene-Rubber (EPR) or Cross-Linked Polyethylene (XLPE)" and Form 1927,-
