    Abstract:With the terminal power distribution circuit for balcony wall lamp lighting,building floodlighting,basement submersible sewage pump and small central air conditioner etc. as examples,the fault protection measures of such equipment are analyzed to determine whether the 30 mA residual current protector is a must for the power distribution terminal circuit of such equipment and the fault protection measures for the equipment terminal power distribution circuit of common civil buildings with TN system of the same kind are further proposed.
    Key words:civil buildings;residual current protector;wall lamps;floodlighting;submersible sewage pump;small central air conditioner;terminal circuit;fault protection
 
    摘 要:以露台壁灯照明、建筑物泛光照明、地下室潜污泵、小型中央空调等设备末端配电回路为例,通过对此类设备的故障保护措施进行分析,判断出此类设备配电末端回路是否必须采用30 mA剩余电流保护器,并进一步给出同类常见的TN系统民用建筑物设备末端配电回路应采取的故障保护措施。
