RCD problem

[Taylortwocities]

When the trip goes out only the power goes off. .

What do you mean "only the power goes off". That means everything!

Power means sockets, cooker, lights, fish tank, everything. If only part of the installation goes off, please say what goes off, and what stays on.

Sorry for the confusion the sockets and cooker all go off when the trip goes out. Lighting stays on and is not affected.

You could have the cooker circuit moved to a non-RCD circuit by an electrician. This will avoid the inconvenience of you losing all the power when the oven element fails. If the Cooker Control (big switch on the kitchen wall) has a socket on it, it will be have to be replaced by a simple switch with no socket, since RCD protection of sockets is an important safelty feature.

However, the RCD does not cause the element to fail. On the contrary, it is the failing element that makes the RCD trip. When the RCD is in the "On" position it has no effect at all on the electricity that passes through it. It is just a switch, albeit one that automatically turns "off" in the event of a fault.

Unless you have beeen unlucky, consider a different brand of cooker next time you buy one. You might like to write a letter of complaint to Smeg about the poor service life of their elements.
