[QUOTE="Robin Spark, post: 80502, member: 5444"] A L to N fault is a short cct and not a leakage of current to earth, therefore the RCD would nt pickup this up as there would be no imbalance of current between the L and N coils inside the rcd and so it would not trip. If the L-N fault was of negligible impedance then a sufficent current would then be produced and then only the circuit breaker would disconnect especially if the terminals were enclosed in a class 2 fitting.
