An RCD will provide additional protection and significantly reduce the risk of injury or death because it will trip when a dangerous level of current flows to earth through the person in contact with the nail.
Coordination of residual current protective devices
The minimum non-tripping time of the upstream device will therefore be greater than the maximum tripping time of the downstream device for all current values. Figure F61 is an example of

Major differences exist regarding the manner in which an RCD unit will act to disconnect the power to a circuit or appliance. There are four situations in which different types of RCD units are used: • At the consumer power distribution level, usually in conjunction with an RCBO resettable circuit breaker• Built into a wall socket
