This Residual-Current Device (RCB) will quickly break an electrical circuit in your caravan to prevent harm from an ongoing electric shock. It works by comparing the current entering the appliance via the live wire with the current leaving the device through the neutral wire; the difference in the residual electric current - if it is too high, the device will interrupt the circuit. 

This appliance is specifically an Eart-Leakage Circuit Breaker. an RCB which is to be used in electrical installations with high Earth impedance i.e. the electrical installation that you use to get electricity in your caravan at the campsite. It is sensible to always use this certified appliance for safety.
