Hi just to clear a few things up yes the oven is rated at 2.2Kw and came fitted with a 13 amp plug which plugs into a socket shared with the gas hob ignition circuit. Another socket is for the freezer and then 2 doubles in the lounge for the electric fire some lights and a filtered surge protected power strip for the house phone and interweb thingy. The trip occurs when just the fan and internal oven light come on but before any heaters are switched on
