36.1 When a 3-conductor cord-and-plug assembly is provided on a portable luminaire, all conductive

parts of a portable luminaire not intended to be electrically live, that are accessible to persons including

during any user maintenance and that have the potential to inadvertently become energized shall be

grounded by being conductively bonded together to the equipment grounding means.

一个产品带金属外壳，金属外壳与电源线地线连接，从金属外壳上有个小金属支架，这个小金属支架通过金属螺母与外壳相接，

然后小支架通过金属螺母固定在金属杆上，金属杆与金属底座相连接。

问：

小金属支架是否需要接地？金属杆是否需要接地，金属底座是否需要接地？
