Abstract

Residual Current Devices (RCDs), or "safety switches" (12), require routine checking in which they are tripped. This leads to a loss in power to their load circuits which can cause significant inconvenience to commercial premises or households. Disclosed is a bypass device (10) for use when testing a circuit breaker connected to an electrical load circuit having at least an active circuit and a neutral circuit, the bypass device characterised by a means of ensuring power is maintained through the electrical load circuit downstream of the circuit breaker after it has been tripped so that no interruption is noticed by the electrical load circuit.
