同时配电箱内的零线排就成了“火线排”，始终带有电压。极易造成漏电甚至引发火灾。如何判断入户线是否接反呢？很简单，测量两个地方——可以用测电笔测量零排，主开关合闸、支路开关全部断开后，如果零排可以点亮电笔，则说明入户线的零火线接反了——前提是配电箱内接线没错。也可以将主开关闭合、支路开关断开后，测量1P漏电开关或1P+N开关的“N”接线柱，如果电笔可以点亮，则证明入户线的零火线接反了。这种情况解决起来很简单：先去电表箱（一般在楼道里）把自己家的断路器断开，把配电箱主开关的进线拆掉，调换顺序即可。

This product is suitable for electronic computers with rated voltage of 500V and cables with high re of anti-interference. Type K B low density polyethylene with anti-oxidation property is adopted for insulation of cable core. Polyethylene high insulation resistance, good resistance to voltage, small dielectric coefficient and temperature and the influence of variable frequency dielectric loss is small, can not only meet the res of transmission performance, and can ensure the service life of the cable. In order to reduce crosstalk and external interference between circuits, the cable adopts shielding structure. The shielding res of cables are respectively adopted according to different situations, such as the method of shielding the hinged combination, the method of shielding the hinged combination, and the method of shielding the hinged combination after the hinged combination. Shielding materials are round copper wire, copper belt, aluminum belt/plastic composite belt three. Shielding pair and shielding pair have good insulation performance. If there is potential difference between shielding pair and shielding pair, the signal transmission will not be affected.
