Definition: A barrater is a type of device or mechanism that helps in protecting against electrical shocks. It consists of a spring-loaded body and a switch, which can be operated by pressing down on the handle. When the handle is pressed down, it will open, allowing the body to dissipate the shock energy. This feature is useful for preventing accidents caused by direct contact with electric currents or equipment. In terms of electrical safety, barraters are often used in conjunction with other safety devices such as grounding systems
