接地漏电保护插座，又名接地故障断路器（Ground Fault Circuit Interrupter，缩写GFCI）或漏电断路器（Residual Current Circuit Breaker，缩写RCCB），是一种应用于家庭住所，以保护用户免受漏电、电击的危害的实用性电气产品。因为其强大的保护功能，已被部分欧美国家强制推行安装。以北美为例，每个家庭用户必须安装5个GFCI插座，分别是浴室、厨房等湿度大、用电器比较集中，而且容易发生漏电事故的地方。

A residual-current device (RCD), or residual-current circuit breaker (RCCB), is a device to quickly disconnect current to prevent serious harm from an ongoing electric shock. Injury may still occur in some cases, for example if a human falls after receiving a shock. In the United States and Canada, the device is more commonly known as a ground fault circuit interrupter (GFCI), ground fault interrupter (GFI) or an appliance leakage current interrupter (ALCI). In the United Kingdom, these are better known by their initials RCD, and a combined RCD+MCB is known as a RCBO (residual-current circuit breaker with overcurrent protection). In Australia, they are sometimes known as safety switches or a RCD. An earth leakage circuit breaker (ELCB) may be a residual-current device, although an older type of voltage-operated earth leakage circuit breaker also exists. In German-speaking countries the device is sometimes known as FI where the F stands for fault (Fehler) and I for the symbol that represents electric current.
