101 1 3. 5. Yes. 230V devices are rated for 230V±10%, so they operate as designed with anything from 207V to 253V. Out of that band, the appliance may not work. Janka. Also, the mains frequency in both Germany and Vietnam is 50 Hz, so that will not present a problem. –. Add a comment.
But: 3,100 watts draws amps of: 14.09 amps @ 220v. 13.47 amps @ 230v. 12.91 amps @ 240v. 12.4 amps @ 250v. If the installation is 240v or 250v then it safely inside the 13 amp of a final ring circuit. The question is, and the regs aficionados can help here, what is the voltage that should be used to assess, as maybe the voltage will vary in an
If you want to use your USA laptop in another country with a different voltage, you may wonder if you need a power converter or adapter. Find out the answer from experts and travelers on Quora, the platform where you can ask any question and get helpful insights.
240V/230V is more harmful than 120V when exposed directly to a human body. Voltage drop and I2R is higher in 120V than 240V for the same distance, wire size conductor and wattage application (Watts = Volts x Amps). Keep in mind that is negligible (3 to 5%) in home based wiring systems.
