There is a demand for more RCD protection of nal circuits, more metering and often more control to meet energy saving targets. The protection provided by these circuits is monitored and, therefore, the RCD immediately switches off any circuit that detects current flowing in an unplanned direction, such as a person accidentally touching a live wire. The great thing is that the residual current device (RCD) provides sufficient protection. EICR in a commercial premises, no RCD protection.
