On reducing the power problem of electric kettle
Open 2 electric hair dryers at the same time. If you do not jump, go and buy a kettle
The rectifier diode can be purchased with a rectifier current of 5A or above, withstanding voltage at 400V (preferably using 500V). Such as BY550-500 diode. A diode for safety, after looking for a three hole socket power supply wiring board (after the success of this experiment only the socket hole wiring board for electric kettle), open wiring board, the connecting wire cut a socket inside the L end and L end of the power line, using diode instead of this the pitch line, can not use positive and negative diode, diode L to replace power socket L terminal, the terminal plate installed can be connected with the power supply and the electric kettle try, careful not to have any appliances plugged in. May you succeed! Ask again if you have any questions.
Dormitory power limit is 800W, you want to use the diode to reduce power efficiency after use, but 1800W through diode is 0.45, get the power of 810W, or greater than 800W limit. You can't use any appliances if you're just a bit too far to use them. I'll show you the serial diode method. You can try it.
