Hm... guessing the wiring at the top is 6mm2 I'd say the home owner wiring is at max. 1.5mm2, rather 1mm2. OUCH!
Let me guess. The typical rating of such a beast is 7-9kW. Assuming a resistive load and an optimistic voltage of 240V that's 29-37.5amps. A 32A breaker probably wouldn't trip at all. Go figure...
