Why We Need More Safety Switches in Our 皇冠APP下注s

安全开关拯救生命. There’s no disputing that fact, and over the past 25 years more and more homes have been fitted with these miraculous devices. 这是好消息!

然而，不太好的消息是 that only around 65% of homes have 安全开关 installed today. 其中, almost none have 安全开关 fitted on all their circuits, with 29% only on power outlet circuits and 39% on power and light circuits. 虽然这是一个 great start to thinking more safely, an electrical fault could still occur on any circuit including the lighting, power outlets, hot water, oven, stove, and 空调. For full protection, most homes would need to have at least 安装四个安全开关.

调查显示，大多数 people believe they are well protected from electrical injury at home, but this isn’t the case when 65% of homes aren’t fully protected by the 安全开关 他们已经安装了. This indicates that our wires have crossed somewhat, and we need to switch our thinking about electrical safety and safety 开关. 

什么是安全开关?

安全开关或残余 Current Device (RCD) is a device that’s designed to cut power to an electrical circuit in a fraction of a second in the event of an electrical leakage (0.03 准确地说是秒). The moment a circuit is detected to be leaking (as would be the case if someone touched a bare wire), the flow of electricity would be 心跳停止了. The electrical flow is stopped so fast that the person doesn’t even have time to receive a shock, and that’s why safety 开关 are so important when it comes to electrical safety!

你可以认出一个安全开关 by the button marked ‘test’ on the front, which is what helps to distinguish it from a circuit breaker, which look similar. 许多家庭都有断路器 installed, but these only protect against overloading and short circuits. 这是 a good start, but not enough to protect someone from electrocution.
