Can a 240 volt circuit handle a 4500 watt appliance?

Without knowing the amperage capacity of the circuit the question is irrelevant. 4500 Watts at 240 volts would draw about 18.75 Amps. Calculating a little extra for safety would mean that you should use a 30 amp circuit. Perhaps that's not the question you were asking.


Can a 240 volt circuit using number-12 wire handle a 4500 watt appliance?

No, the 20 amp (AWG #12) wire will be too small, you need to use AWG #10 wire. Even though 4500 watts is less that the 20 amp it can only be loaded to 80% by NEC rules which is 18.75 amps. The #12 wire would be overloaded so defiantly use AWG #10.


How many volts is 4500 watts?

To determine the number of volts in a circuit with 4500 watts, you need to know the current flowing through the circuit. The relationship between power (in watts), current (in amperes), and voltage (in volts) is given by the formula P = V x I, where P is power, V is voltage, and I is current. Without knowing the current, it is not possible to directly convert watts to volts.


What is 4500 ohms to k?

K refers to kilo, which is 1,000. So 4,500 ohms could be written as 4.5k ohms and pronounced 4.5 kilo ohms.


What size breaker needs to be installed for 4500 watt 240 volt hotwater heater?

Answer for USA, Canada and countries running a 60 Hz supply service.You need a 30 amp 2-pole breaker and #10 AWG wire.As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
