<强>电弧故障电路断续器（ACFIs）去激励电路在检测到电弧故障时，防止过热和可能的燃烧。ACFIs加强安全在任何家庭，并且需要一些新的建筑，由国家不同。

在过去的十年左右，约电弧故障电路中断，并在住宅建设其所需使用的讨论官员，机构，企业和相关建筑行业个体之间已经炸开了锅。Change can be difficult but “only the wisest and stupidest of men never change," as Confucius said. Change has occurred consistently in residential electrical systems since Thomas Edison unveiled the first electric light on New Year’s Eve, 1879. Knob and tube, cloth-braided, PVC-jacketed, two wire then three wire, fuses then breakers… the list goes on and on. Change happens. Most of that change can be attributed to our steadily increasing understanding of electricity since we were first electrified. With its increasing use in our homes, and the considerations of inhabitants’ safety and the prevention of property damage, it is not surprising that regulations have continued to change. So why do we resist? We should expect change and grow with it, particularly when it is in the interest of our own safety and can prevent the loss of property.
