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.
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.
NEC 220.52(A) & (B) state that an additional load of not less than 1500 volt-amperes shall be included for each two-wire small appliance circuit and each laundry circuit.
Yes a 10 amp fuse can be used to protect a 240 volt circuit. The amperage rating of a fuse is based on the given amperage load of the circuit. The voltage rating on a fuse must match or be higher than the voltage that is applied to the fuse. In other words you can not use a 240 volt fuse on a 277, 347, 480 or 600 volt circuit but it can be used on a 120 volt, Manufactures of switching equipment today make it impossible to interchange different voltage fuses to be installed in higher voltage switches.
No. 20 amps at 120 volts will handle a maximum of 2400 watts. And you should never continuously load a 20 amp 120 volt circuit to no more than 1920 watts.
No, a 240 volt device runs on 240, and a 120 volt device runs on 120. Attempting to run a device on incompatible voltage results in damage.
Using a 265-volt appliance on a 220-volt line can be risky and may damage the appliance, cause a short circuit, or result in a safety hazard. It is recommended to use voltage converters or transformers to ensure safe operation of the appliance.
To install a 220-volt appliance at home, you will need to ensure you have the correct outlet and circuit in place. Hire a qualified electrician to install the appropriate outlet, usually a NEMA 6-15 or 6-20 for 220-volt appliances. Make sure the circuit can handle the load of the appliance to prevent any electrical hazards.
Yes. Circuits in a home are 120 volts but people tend to call them 110 volt circuits. The 120 volts you read on the appliance is the maximum voltage the appliance can handle. The actual voltage you will read at any outlet will range from 110 to 120 volts.
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.
Yes, you may need to change your circuit breaker to one that can handle the higher voltage required for a 230 volt window AC unit. It's important to have a circuit breaker that is compatible with the voltage and amperage requirements of the appliance to ensure proper function and safety.
No, the applied 110 volt is too high for a 3 volt appliance. The appliance would burn out right away.
Yes
The voltage cannot just be increased in a circuit because there is a risk of damage, blown circuit breakers and/or fire. However an appliance desgined to run on 220 v will use 6/11ths of the current used by an identical appliance designed for 120 v.
NO
That appliance might last longer if you use an eight volt adapter rather than a nine volt adapter.
NEC 220.52(A) & (B) state that an additional load of not less than 1500 volt-amperes shall be included for each two-wire small appliance circuit and each laundry circuit.
A volt can not be connected to a circuit.
