An electric toothbrush has 2-4W (watts).
Using the equation Volts X Amps = Watts, you can take 3000 watts / Volts to get your answer: 3000W/240V = 12.5A or 3000W/120V = 25A So, at 240 volts you will use 12.5 amps for 3000 watts of power. Or at 120 volts you will use 25 watts.
Amperage (coulombs/sec sort of like volume) and wattage (power) are independent of each other if you know the voltage you can calculate amps but they are not the same thing. 3000 watts/X volts=amps ex. 3000 watts/110v=27.28 amps
A typical home boiler uses 3000 Watts. 3000 watts is not the correct answer. Watts = volts x amps, or if converting to btu 3000 watts = 10236 btu. At typical household votage of 120, 3000 watts would equal 25 amps and no boiler uses that much current and if your desire is to convert btu to watts I would suspect the average boiler output is far greater than 10K btu. Determine the output in btu/hr of the boiler in question from the MFR`s nameplate and divide by 3.412 3.412btu=1watt/hr. My home boiler uses 3000 watts, it's in my kitchen cupboard and it runs on a 240 v supply.
With filing fee's and dedicated line and installation $3,000. Depending on model
The advantages of an electric downdraft cooktop is that it is very much more convenient. This type of cooktop would be easier to use than the regular kinds out there.
The advantages to an electric downdraft cooktop versus an electric one is that the way the draft of the aroma from the foods you are cooking is dispersed.

Their are pros and cons to an electric cooktop. Gas cooktops are often said to cook more evenly, but electric cooktops are less dangerous due to lack of open flame. A gas cooktop may also be less expensive to run.
An electric cooktop uses a great deal more electrical energy than a gas cooktop. The electric portion of the gas cooktop runs the electronics (clock, timer, ignitor, oven light, etc.), and these are small electrical loads. An electric cooktop uses more electrical energy cooking a batch of, say, pasta sauce, than a gas cooktop would normally use in a month or two. There just isn't a good comparison as there is such a broad difference in the electrical usage of the two units.
The General Electric JGP945 30in. Gas Cooktop is available in both stainless steel and black finishes.

An electric downdraft cooktop is a step up from your traditional cooking options. Luckily national chains, such as Sears, Loews and Home Depot carry them.
Fixed electric cooktops will cook food much more evenly than gas cooktops, but the electric bill will be considerably higher.
