Residual Current Monitors RCMs are used to monitor electrical installations. They provide pre-warning of developing faults when the pre-set value of residual current is reached.

• RCMs are for use in installations under the permanent supervision of an "electrically instructed person".
• RCMs do not provide protection i.e. they cannot be used in place of an RCD or MRCD: See Reg. 411.

Note: Must be used with Doepke residual current monitoring C/Ts, please see details below.
