RCD Testers

An RCD (Residual Current Device) is a protective device that instantly breaks an electric circuit to prevent series harm from an ongoing electric shock. In the case of a single-phase circuit, the device monitors the difference in currents between the line and neutral conductors. This life-saving device, designed to prevent you from getting a fatal electric shock if you touch something live, (e.g. bare wire), offers a level of personal protection that ordinary fuses and circuit-breakers cannot provide.
RCD, is a generic term applied to a family of products which open automatically in response to a residual current equal to or greater than the RCD’s rated residual operating current. This generic term is often applied to the following:
RCCB - Residual Current Circuit Breaker
RCBO - Residual Current Breaker with Overcurrent protection
SRCD - Socket outlet RCD
PRCD - Portable Residual Current Device
An RCCB differs from an RCBO in that the RCBO will additionally respond to overcurrent conditions whereas the RCCB will not respond to such conditions. The term SRCD is applicable to an RCD which is an integral part of a socket outlet or which is fitted in a box immediately adjacent to a socket outlet.
RCD Technology
RCDs may be distinguished by their technology:-
Voltage Independent RCDs (VI). These RCDs rely on the energy of the residual current to activate the RCD. These devices are sometimes referred to as Electromechanical RCDs, and are voltage-independent in operation.
Voltage Dependent RCDs (VD). These RCDs use the mains supply voltage to power an electronic circuit and the tripping mechanism to activate the RCD. These devices are sometimes referred to as Electronic RCDs and are voltage-dependent in operation.
How do they work?
Under normal circumstances, the current flowing in the two wires is equal. When an earth leakage occurs due to a fault in the circuit or an accident with the equipment, an imbalance occurs and this is detected by the RCD, which automatically cuts off the power before injury or damage can result.
RCDs protect humans against electrocution in a way that fuses and circuit breakers do not. If you have a new circuit installed, or a circuit is substantially modified, you may be required to have an RCD fitted under the Building Regulations (Part P) or BS7671 wiring regulations. This is a legal requirement.
Using the wrong type of RCD can result in total loss of protection. RCD testers need to be tested every 12 months so any problems can be identified before they result in injury or equipment failure.
