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.

Does a 900 to 950 watt require a separate electrical circuit?
Depends more on the application and what else you might have on a current circuit you would use if you didn't install a separate circuit. At 120 volts you are only talking about drawing 8 amps. On a 15 Amp circuit this is fine. However, if there is a motor involved there may be excess start-up currents. There are certain appliances like stoves, refrigerators, dryers, dishwashers and so forth that require separate circuits. If you have a small heater you move from room to room then you can use an existing circuit that would not trip when you added the appliance. Use the cord that comes with the device directly into an outlet rather than using an extension cord. If the appliance needs to be hardwired into a box then use a dedicated circuit.

What is the definition of circuit diagram?
A circuit diagram, or schematic, is a picture of how the components in a circuit are connected together. Using the diagram, you can perform analysis of the design. You can also use it to troubleshoot a fault in the circuit.
How do you make a circuit without wires?
Using tracks of metal such as on a PCB (printed circuit board) or using other electrically conductive material such as the graphite in 'lead' pencils.
What happens when you plug 120vac appliance into a 30 amp line?
Most 30 amp home circuits are 240 V. If you try to run a 120 V appliance using 240 V, the appliance will immediately self-destruct.However... if you actually have a 30 amp 120 V line to which you want to plug in your appliance, the only issue would be fire protection. Circuit breakers are in place to prevent too much current from passing through a wire. Wires have the capacity to carry only a specific amount of maximum current. a 10 Ga wire is generally used in homes for a 30 amp circuit. It doesn't matter if it's carrying 120 or 240 V, it still needs to be a 10 AWG conductor.However, you need to make certain that all conductors, outlets and circuit breakers are matched to each other when wiring a home or business.The appliance will only use the amperage that it needs UP TO THE MAXIMUM RATING OF THE CIRCUIT, providing that the VOLTAGEmatches.So the short answer is, just make certain that the line voltage is right for your appliance and that the circuit is rated at a high enough amperage to handle the appliance.
What is a circuit breaker for?
The circuit breaker obviously breaks the circuit but only in an attempt to stop a surge of electricity going through your house and possibly hurting you if you're using an appliance, or popping light bulbs and most likely starting a fire.
Can you use 15 amp appliance on 20 amp socket?
Yes, the amp rating is a measurement of the highest amp load it should carry. So a 15 amp appliance will work on a 20 amp socket but you wouldn't want to use a 20 amp appliance on a 15 amp socket.
Can you give an example of a sentence using the word appliance?

Why would using a small kitchen appliance trip the circuit breaker for the bedrooms and not for the outlet that it is plugged into?
If a small kitchen appliance is tripping the circuit breaker for the bedrooms and not for the outlet it is plugged into, it could be due to the difference in electrical load. The bedrooms circuit may already have a higher load from other devices plugged in, whereas the individual outlet might have a separate circuit with a lower load. The small kitchen appliance could be exceeding the capacity of the bedrooms circuit, causing it to trip. It is recommended to redistribute the load or use a different outlet on a different circuit.
When using a 30 amp fuse on a single circuit in a series will you have a problem using a 10amp and a 23.9 amp appliance at the same time?
Well, do the math. You shouldn't run a combined load of 33.9 amps off a circuit fused at 30 amps. Depending on the type of fuse (if it is a fuse and not a circuit breaker), the fuse may burn instantly or hold for a while before burning.
Why the high resistance earth fault in the appliance increase the risk of electric shock when using appliance in earth situation?
If the earth connection has a high resistance it is not capable of acting as a true earth. For example, the high resistance might mean that the fuse or circuit-breaker will fail to operate when there is a fault.
What is a sentence using the word appliance?
Carol and James headed straight to the appliance department to buy a new refrigerator. Some synonyms for appliance are machine, gadget, and apparatus.
Which will do less damage between plugging a 110-volts appliance into a 220-volts circuit or plugging a 220-volts appliance into a 110-volt circuit?
You will have trouble plugging a 220 volt appliance into a 110 volt outlet because both have different polarities for the plug and receptacle that make it impossible for that action to happen.Altering the plug isn't too good of an idea, as the voltage demand of the appliance would be too heavy for the wiring.
Circuit continuity is measured using?
Circuit continuity can be tested by using an ohm meter.
How much energy is wasted by leaving an appliance on standby?
Leaving an appliance on standby means it is using 40% of the energy it would if it was actually running.
