求翻译：所有设备至少有两点引出地线相连。接地电阻不大于4Ω；不同用途接地共用一个总的接地装置时，其接地电阻应符合其中最小值。是什么意思？ 待解决

All devices have at least two points led to ground wires connected. Earth resistance not more than 4 ω; for different applications share a general grounding grounded appliance is its grounding resistance should be consistent with the minimum value.

There are at least two points emerged from all of the equipment connected to line. grounding resistance or less than 4 Ω; different uses earthed share a general grounding devices, its grounding resistance should be consistent with the smallest value.

All equipment have at least two points draw out the grounding to be connected.The earth resistance is not bigger than 4Ω; When the different use earth uses in common a total grounding, its earth resistance should conform to minimum value.
