5.2.11.2 Compatibility with residual-current-operated protective devices in case of low
leakage current
A residual-current-operated protective device (RCD) with rated fault current Ifn ≤ 30 mA may
be used to provide protection in case of indirect contact and/or supplementary protection in
case of direct contact. It is presupposed that the leakage current of the EE(s) according to

这里不是讲的漏电流的问题,是讲剩余电流(residual current ,不知台湾是否这样翻译),剩余电流是一种故障电流,是在发生故障时相线和中线的电流不同产生的矢量和。所以为了防止故障产生需要在设备上增加剩余电流保护装置(RCD),漏电流是一种正常的电流。以上的内容是讲,当漏电流很小的情况下,使用额定值小30mA的剩余电流保护器(RCD)也不会产生误动作。具体的翻译请上下文。
