充电产品,是否一定要有保险丝? 就IEC60950而言,我个人认为根据3.1.1下面的这段话,应该是要有overcurrent protection的,当然不一定是保险丝
2 S4 o! C" L( k1 P. U. mAll internal wiring (including busbars) and INTERCONNECTING CABLES used in the distribution of, v$ _5 B' F4 o6 I c

Wiring not directly involved in the distribution path does not require protection if it can be
