常見例句雙語例句Ground fault circuit interrupters (GFCI's) or residual current devices (RCD's) are required on receptacles that are located in wet locations or outdoors.在溼潤的地方或戶外作業(yè)時,插座上必須要有接地故障斷路器(GFCI) 或賸餘電流裝置(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.減小接地故障點的殘流有利於接地電弧的瞬間熄滅及降低間歇性電弧接地過電壓。 返回 residual ground current
