WebResidual Current Device Testing and Safety. Residual Current Devices, or RCDs. are safety switches that prevent people from getting electrocuted in homes and businesses. The device monitors the flow of electricity as it enters a property from the main distribution panel. A surge of electricity, or an imbalance of electrical power, can cause ... WebApr 19, 2024 · Of course a real RCD tester will pull up the CPC towards live, but the time and the current are limited to safe, if painful, values, should a human being be the main fault path for any reason. An ELFI (loop) test may involve higher than 'safe' currents for sustained exposure, but I'd hope folk read the handbook and start out small before working up and …
