我有一个电动淋浴和一个升压泵安装3个月前。现有的备用线路开关在楼下厨房里的保险丝盒是用来运行电缆从保险丝盒到浴室(到隔离开关箱在浴室的墙外)。然后其余安装隔离开关箱的电在我的浴室淋浴。电工说没有足够的水压力所以我需要一个增压泵公元前这对我来说是一个意外,我在一开始就说b4雇佣他的重力美联储和他实际上是建议我买Triton T90容易适应电动淋浴。然而,楼上的电、光、淋浴,楼下电器关掉/突然很经常。电工之后第一次发生这样的事情了,只有检查淋浴隔离开关,说一切很好。现在是被绊倒电力很多次,甚至当我关掉,在主电开关不来吧。然后后来我打开保险丝盒的盖子,突然没有什么都不做楼上的灯光和电器又接着说。有什么问题吗?我担心错误的RCD电工布线这可能已经损坏的同时增加电线/电缆通过使用备用电路的保险丝盒电动淋浴。 We decided not to use the new shower since last 2 days but even without using it all the lights upstairs and kitchen appliances stop working suddenly anytime without warning. Is it dangerous? Can faulty RCD start a fire in the wall or the fuse box? The electrician is extremely unreliable and might not come and test everything needed for weeks. He also refused to provide me with Safety certificate for last 3 months. Now he did at last but I had lost of electricity problems and flooding problems since he fitted new electric shower. Any advice please?
