Purchased a used neff double oven that has not been used.
I turned the bottom oven on then the top oven after about 4 minuites the earth breaker tripped, I reset it turned the bottom oven on all was fine.
Turned the top oven on and it tripped again. I then only turned the top oven on and it tripped another 4 times only on the earth breaker
The earth breaker is rated 63A and the circuit breaker is rated 32 A the circuit breaker is not tripping ?

The earth circuit breaker is fine i think it could be a problem with the top oven ?
thank you for your replies

An Earth Leakage breaker feeds several circuits each with its own current rating. A typical Earth Leakage Breaker will trip at 30mA leakage but it also has to cope with the combined current of all the circuits it protects - typical 63A or 100A overload breaker.

I would like to think the earth breaker is mA not A however this sounds like a classic damp element due to storage.you need to dry the element or replace
