The powerswitch for a Quooker system and CUBE is a three-way adapter that allows you to connect the Quooker tank, the Quooker CUBE and another appliance, such as a dishwasher, to the same outlet. This additional appliance may be a maximum of 2,700 watts. The power switch is designed to prevent circuit overload, as it detects when the other appliance is in use and switches the Quooker tank to standby mode if the other appliance consumes too much power. This means that the other appliance continues to operate as normal and the Quooker system is still able to drain the existing boiling water, but no longer heats new water while the other appliance is in use.
