[QUOTE="sparkytim, post: 262937, member: 8627"] Yup (cm) The fauly was a N-E short on a wall light. Now comes the interesting bit, how come the RCD was disabled? We need to remember that current is Lazy, (Allways looks for and follows if possible the route of least Resistence) I allways find as others, it helps to Draw out the circuit and route of Fault current, that should help in solving this one. Sammers Bonding not an issue [/QUOTE]
