The majority of electrical fatalities could have been prevented by the use of a properly installed Residual Current Device (RCD) , and regular testing to ensure they are working correctly.
RCD’s also protect against fire caused by faults in appliance, tools and wiring. If these faults go undetected they could cause a fire or personal injury. RCD’s provide a means of early fault detection.
