¿µ¹®³»¿ë¿ä¾à This standard presents a minimum cross sectional area for various conductor condition which references to IEC standard(60364-5-54). And this standard provides the commonly used predetermined values of conductor thickness abstracted from telecommunication operators. Provides basic calculation formula which are originated from the IEEE Std 80 and the same IEC standard above mentioned.
