在某住宅楼验收过程中,发现户内普通照明回路从配电箱到灯具穿两根线,即没有穿PE线。施工单位解释,该工程为毛坯交房,户内照明预留灯泡,白炽灯座内没有PE接线柱,PE线都没地方接,故不需要穿PE线。那么户内普通照明回路是否需要PE线呢?查看图纸及设计标准住户照明配电箱系统图中照明回路设计穿三根线,即L/N/PE线(相线/零线/保护接地线)。
In the acceptance process of a residential building, it was found that the indoor general lighting circuit passed two wires from the distribution box to the lamp, that is, no PE wire was worn. The construction unit explained that the project is for the delivery of roughs, reserved lighting for indoor lighting, there are no PE connection posts in the incandescent lamp holders, and there is no place for PE lines, so PE lines do not need to be worn. Then do the indoor general lighting circuit need PE line? Check the drawings and design standards The lighting circuit design of the household lighting distribution box diagram wears three lines, namely L/N/PE line (phase line/neutral line/protection ground line) .
