Range cooker fusing

[jobray]

I have recently moved into a property with a range cooker already installed, it has 2 ovens a seperate grill and warming oven, the hob is gas, when I try to use the grill and 2 ovens the system cuts out, I have been told that I need a 45 amp breaker as mine is only 30 amp, does this mean that my cable will need upgrading and how do I tell what size the existing cable is? Any help will be much appreciated so that I can talk to an electrician and have at least some idea of what I'm on about. thanks in advance

If you are being told that it must be a very powerful oven - is this in the manufacturers instructions or is it 'yer mate down the pub'.

Generally for an oven without a hob, fed by 6mm T&E cable, a 30Amp fuse or 32 Amp MCB is more than adequate.
You don't say what is tripping but I would suspect that one of elements is loosing its integrity and needs replacing.

Hi, Thanks for your quick responses, it was the nice man in our local electrical shop maybe he's not so nice though and thought he could make some easy money out of a dumb blonde , previous owner didn't leave an instruction manual but just found it on the net and you're right the 30 amp is adequate so it must be the element, glad about that as I didn't even want to think about what rewiring was going to cost me. thanks for your help
