New Oven tripping RCD

[Ohmslaw]

Installed oven (supplied off 13amp plug) and turned it on last night, only for RCD to trip. Have since taken oven out and checked connections, seem fine. Have tried plugging another appliance into oven socket- works fine. Have plugged oven into another socket on same ring - trips RCD.

Have temporally disconnected earth from oven plug and it still trips, so this should rule out earth leakage in oven?

Read about sometimes oven elements have moisture in them?

Thanks

There must be another path to earth from the oven, otherwise there is nowhere for current to flow that would cause an imbalance between L & N - though its feet and the floor? Or through you when you touch the oven (you might not feel anything).

Even if there is moisture in the elements, that would be still be earth leakage as the current needs somewhere to go other than back down the neutral.

As davelx has said for the RCD to trip there has to be a path to earth.

Exactly when does the RCD trip ? Does it trip when the oven is plugged in ( socket switched on ) or when one of the elements in the the oven is switched on ?

Have tried plugging another appliance into oven socket-

Did you use a kettle with a 2kW power rating or a small appliance..?

My reason for asking is because there can be a fault ( Neutral to Earth ) on a different circuit which will trip the RCD only when there is a large load on another circuit.

Is it a new oven?

Try it in a different socket, perhaps using an extension lead. If it still trips take/send it back to the supplier.

... but I suppose, just to be sure, he should try a socket on a different circuit (ideally one protected by a different RCD, but that may not be possible) if he can.
