We're on the 3.3Kw tarrif for electricity. If we switch on the oven all the power goes off even if the oven is the only thing using power. What's strange is, it's not the breaker for the oven circuit that trips, it's the main breaker which kills everything.
I assume you should be able to run an oven on the 3.3kw tarrif or are we overdrawing the supply. The cooking rings are no problem.
Could be a faulty oven, faulty wiring, faulty breaker too. Just trying to get a bit info before calling someone.
I've checked the plug and the junction boxes and don't see anything obvious.
