[QUOTE="Doc Hudson, post: 493488, member: 1607"] I will try again, as I didn't ask if the oven was on a radial circuit. Is the oven circuit connected to an MCB that is supplied from an RCD, or does it have its own dedicated RCBO? If it is an MCB supplied from an RCD, do other MCB's share this same RCD. i.e. it is very common to have a consumer unit with one or two RCD which each supply multiple MCB's In addition to what the others have said regarding elements, it is also true that some oven manufactures used to recommend their appliances were NOT connected via an RCD due to natural leakage issues. Have you verified that you RCD is operating within its correct specification, i.e. not over sensitive? Multiple circuits each with a proportion of natural leakage can cause RCD's to trip, when there is no actual genuine single fault. You may well have a faulty element, But it is also true that you may not. I was just trying to establish if you have confirmed your RCD symptoms occur with a known good RCD (or RCBO) and no other circuits that could influence the operation of this RCD (or RCBO)? Doc H.
