Thanks very much for your help, I'll tackle tomorrow! Just for closure - any ideas as to the source of the leakage from the oven? I'm trying to understand why this problem would have started occuring after a long time? Cheers.

The oven circuit is the forst to the right of the trip switch. I assume I kill the power with the main switch (there is no other switch upstream) relocate the trip to the oven switch to the left and relocate the neutral? Thanks.
My circuit breaker (RCCB 30mA) has recently started tripping intermittently. By observing what was on at the time I think I've tracked it down to my NEFF 1051 oven. I'm fairly sure the problem isn't a straight forward short because that would also take out the oven circuit. I've had the back off...
