IEEE Standard for Metal-Enclosed Low-Voltage Power Circuit Breaker Switchgear---Amendment 1: Short-Time and Short-Circuit Withstand Current Tests---Minimum Areas for Multiple Cable Connections

This amendment revises IEEE Std C37.20.1-2002. Use of “dummy elements,” previously allowed for short-circuit tests in 6.2.4 and 6.2.5.2, is eliminated. Errors made in converting areas in Table 10 to metric units are corrected.
