- Ground fault circuit interrupters (GFCI's) or residual current devices (RCD's) are required on receptacles that are located in wet locations or outdoors.
在湿润的地方或户外作业时，插座上必须要有接地故障断路器（GFCI） 或剩余电流装置（RCD）。 - The reduction of the residual current of the ground-fault point is beneficial to the extinction of the grounding arc and to the reduction of the intermittent arc grounding over voltage.
减小接地故障点的残流有利于接地电弧的瞬间熄灭及降低间歇性电弧接地过电压。 返回 residual ground current
