Power trips when using both ovens

[gmc1]

I've got a Cookmaster CM101 oven which is giving a problem in that when I use both ovens it trips the power

I can use the left or right oven separately without issues, but when I us both it trips the power after a few mins.
I have only recently used both ovens since buying the house so it might well have always been broken (and previous owner said nothing)

The switch that is tripping is the one on the far right. (RCD?)


Any ideas on this? Sounds like some overloading issue but as it might have never worked not sure if its a wiring problem or something with the oven?

An RCD will not trip because of an overload, just an imbalance in the current flow ( ie conducting live to earth or neutral to earth ). Possibly something getting hot & shorting out (cable or other component) only when both ovens are in use. I doubt this will be a diy job but you could check for any obvious sign of burning or over heating.

Thanks for the reply. I opened it up and one of the wires looked suspect. Replaced and so far good Was probably intermittently touching ground
