If it is similar to ours at home it is rated at 2.9 kw, which means it is drawing roughly 12 amps when running-2900watts divided by 240 volts=12 amps resulting in popping 10 amp circuit breaker.Most mains kettles sold for caravan use are 800,900 or 1000 watts which equeals approx 4 amps allowing you to run electric heater,microwave,watch tv & boil kettle all at the same time!It only takes an extra couple of minutes to boil, so she who must be obeyed says i've got time to fill aquaroll whilst i'm waiting!!
