图解水电改造施工规范图解水电改造施工规范●电气导线的敷设应按装修设计规定进行施工,配线时,相线(L)宜用红色,零线(N)宜用蓝色,接地保护线应用黄绿双色线(PE)。                                                                                                                      红、蓝、黄绿三色线是标准配置线。                                                        这处插座线全部是蓝色线,电工接插座面板时要好好测一下了。                                              当然不一定非要用红色线和蓝色线用做相线(火线)和零线,象左面这张图片里这样,                    用蓝色线和绿色线做火线和零线也是可以的,只是用红色线和蓝色线更规范而已。                (注:不管用什么颜色的线,有一点必须遵循,即:同一住宅内配线颜色应统一。)●室内布线应该穿管敷设,不应该有电线外露(除现浇混凝土楼板顶面可采用护套线外)。                                                    这段外露的电线如果被水泥砂浆掩盖在里面,时间长了,可是一个隐患!!●管内导线总截面积不应超过和管内径截面积的40%。                                            ●暗盒与线管必须通过锁母连接。                                                                        正确的锁母连接图。                                                            这处地方,单线抽拉时,容易划伤外面的绝缘皮。●空调电插座、厨房电源插座、卫生间电源插座、其它电源插座及照明电源均应设计单独回路。                                          某业主家应该有8个回路:4个空调电源插座+厨房电源插座+卫生间电源插座+其它电源插座+照明电源。            可配电箱内只有7个回路。经查,原来是主卧和次卧的空调电源共用了一个回路。这属于不规范施工。●吊平顶内的电气配管,应采用明管敷设,不得将配管固定在平顶的吊杆或龙骨上。灯头盒、接线盒的设置应便于检修,并加盖板。使用软管接到等位的,其长度不应超过1m。软管两端应用专用接头与接线盒,灯具应连接牢固。各种强、弱电的导线均不得在吊平顶内出现裸露。                                                                            正确布线照片。                                                                            未使用灯头盒。                                                            吊顶内电线应用线管敷设到位。不应该留下这样的“半拉子”工程。                                                                          软管长度超过1米。●线路施工结束后,所有的线管须做临时固定和保护。                                                                        地面的线管用铁丝固定。                                                                                线管未用卡钉固定,松动。                                                          线管固定工作未到位,全部躺倒在地,内部的线缆必定受损。●电线导管与水管在同一平面间距大于100mm,,不同平面间距大于50mm。                                                              洗衣机水管与插座线路共用一根墙面开槽!!!为将来留下安全隐患。                                                                  地面水管
