Proper hierarchical design of the distribution system and selection of circuit breakers are fundamental to achieving selective protection and ensuring power supply reliability. According to GB 50054 and IEC 60364 standards, low-voltage distribution systems are typically divided into three levels. (1) Power distribution from the primary main distribution board (distribution cabinet) to secondary distribution boards can be branched; that is, one main distribution board may supply power via multiple branch circuits to several secondary distribution boards. If products and components from other manufacturers are used, these must be recommended or approved by Siemens.
