Actually the NEC says that the load on a branch circuit can only be 80% of the breaker size since Some appliances use a more energy to start up. so to be legal, you could only have a 1440W load on a 15 amp circuit, and 2880W with a 240 v 15 amp breaker.
Another Answer You really should be asking how you can estimate ENERGY (not 'power') consumption, based upon a wattage rating. The term, 'wattage', is a slang term for 'power', which is expressed in watts. Power is simply a rate, the rate at which energy is being consumed, and energy (for the purpose of billing, at least) is expressed in kilowatt hours.
So if you know the power ('wattage') of your load, then you must ensure that it is expressed in kilowatts and, then, multiply it by the number of hours that the load is operating. This will then tell you how much energy has been consumed over that period, expressed in kilowatt hours.

How many kilowatts per hour does a flat screen tv use?
None. There is no such thing as a 'kilowatt per hour'. If, on the other hand, you are asking how many 'kilowatt hours' a flatscreen television uses, simply look at its nameplate to find its power rating in kilowatts (more likely, it's in watts, so you need to divide by 1000), and multiply it by 1 to find the number of kilowatt hours consumed over a period of one hour.
Where can you find the power rating of an electrical appliance?
Normally the power rating of an electrical appliance can be found on its 'Rating Plate' or, if there isn't one, use the following formula W = A x V, where W = watts, A = current and V = voltage.
How do you find out the power rating of your power supply?
You can find the power rating of your power supply by looking at the label or sticker on the unit itself. It should indicate the maximum power output in watts (W). You can also check the manufacturer's website or product manual for this information.
How many kilowatts in 1kva?
Its a bit of a trick question. 1 watt is one volt-amp except in situations where the power factor has increased or decreased that ratio. For instance with a power factor of .8 a volt-amp is equal to .8 watts. So with a perfect power factor 1 kva (kilo-volt-amp) is equal to 1 kilowatt. But if the power factor is something other then 1 you can find it by pf*w=va.
Convert bhp to kw?
To convert brake horsepower (bhp) to kilowatts (kW), you can use the following formula: 1 bhp is approximately equal to 0.7457 kW. Simply multiply the bhp value by 0.7457 to get the equivalent value in kilowatts.
How to find kilowatt-hours (kWh) from kilowatts (kW)?
To find kilowatt-hours (kWh) from kilowatts (kW), you need to multiply the power in kilowatts by the time in hours that the power is used. The formula is: kWh kW x hours. This calculation will give you the total energy consumed in kilowatt-hours.
How many kilowatts per hour?
Kilowatts per hour (kWh) is a unit of energy that measures how much power is used over time. It represents the consumption of one kilowatt of power for one hour. To find the total energy consumption in kWh, you multiply the power in kilowatts by the number of hours the power is used. For example, using 2 kilowatts for 3 hours would equal 6 kWh (2 kW × 3 h = 6 kWh).

What is amperage input of transformer on 208 3 phase?
The amperage input of a transformer on a 208V three-phase system can be calculated using the formula: Amperage (A) = Power (Watts) / (Voltage (V) x √3). To determine the amperage, you need to know the power rating of the transformer in watts (or kilowatts). Once you have that, you can plug the values into the formula to find the input amperage.
If kilowatts are known how to you find the proper wire size?
Wire size needed depends on amperage, not watts. If you know the voltage of the power supplied you can calculate the amperage using this form of the "power formula":A = W / VThen there are tables that tell the amperage each wire gauge is capable of carrying. Just select the gauge that has the amperage rating just larger than you calculated.
How you find out amphere only if you know kilowatts?
Kilometers
How many watts in 26kw?
To find watts in kilowatts multiply kilowatts by 1000. In this case, 26 x 1000 = 26, 000 watts.
How do you find the current rating of a zener diode if the power rating is 500mw and a voltage rating of 10v?
A zener diode with a rating of 500 mW will pass 50 mA at 10 V. (Power = voltage times current)Note: The question appears mis stated, in that it states a rating of 500 MW, not 500 mW. To my knowledge, there is no zener with a rating of 500 MW.
How do you figure out the amps of a transformer when it only tells you it puts out 20 vdc?
I suspect you are referring to an external power supply for a device, which consists of a transformer and a smoothing circuit of some kind. Look on the device it powers, there may well be a rating plate or an input fuse. You might also find a VA rating or wattage rating. If so, Google for power formulae to manipulate to find amps.
What is the equation to find the amount of energy used. By appliance?
The equation to calculate the amount of energy used by an appliance is: Energy (kWh) = Power (kW) x Time (hours). Multiply the power consumption of the appliance in kilowatts by the number of hours it's used to find the total energy consumed in kilowatt-hours.
