It may or may not. And because you are going to a smaller fuse than before, it is safe to try it.

What kind of breaker and wire size do you need for a for a heater that is 208 V 19 A 4100 W 2 wire 1 phase?
If the heater has a specified branch circuit rating with the manufacturer's information then follow that. If not then assuming it is to be run more than 3 hours per day: 19.7 A x 1.25 = 24.6 A Next size standard breaker is 25 A (see NEC 240.6) So you will need #10 AWG Copper and a 25A 2 pole breaker.
How many amps does 3000 watts pull?
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.
What size breaker to use on a 4500 watt water heater?
Divide your wattage by your voltage to get your amperage.4500/240=18.75 Amps12ga. wire "can" handle 20amps, however, You should only load a wire to 75% it's max. You are beyond 15amps, so 10ga. would be a good idea, and may be required by your local building codes. Remember, in a brownout (voltage drop) the amp draw will go up. You want to keep below 75% load to allow for this.On 12ga. wire you would be at 93.75% of it's 20amp rating. (Dangerous)On 10ga. wire you would be at 62.5% of it's 30amp rating. (Safe)On 8ga. wire you would be at 46.875% of it's 40amp rating. (Overkill)If you use 8ga., make sure the conductors will actually fit into the terminals on your breaker.If you house doesn't have true 120v/240v power, the amperage will be higher. For example, if you power is actuall comming in at 110v/220v, the ater heater will draw 20.45amps. This would exceed the rating of the 12ga. wire, and raise the load on the 10ga. and 8ga. to 68.16% and 51.12% respectively.Regardless of the wire size you choose, use a 20amp breaker (25amp if you voltage is less than 240). If the water heater draws more than 20amps, you could have a problem. The wire is not the only thing that can burn your house down.Correction to above. If voltage decreases in a resistive circuit, wattage will go down, as will current draw. Resistance stays the same.
Can i get 9V to 110V transformer in the market?
Sure. You can go a couple of ways. You can look for a 110v to 9v transformer, if you can find one, or you can get a 110v to 18v center tapped transformer. If you get the second one, when you hook up the 9v side, you connect between one of the ends of the 18v coil and the center tap. Right now you're thinking, "I said a 9v to 110v transformer, not a 110v to 9v." That you did, but transformers don't care about that--they'll step voltage up as readily as they'll step it down. (Back when all we had was tubes to work with, transformers with a 6v winding and a high-voltage winding--300v, 400v, 2500v, whatever--were very common because tubes need a LOT of voltage to work.) There are two things you really should think about here if you're trying to take 9v to 110v. First, if your intention was to get line voltage out of a 9-volt battery, stop right here. Transformers only work with AC voltage, and a battery puts out DC. The other thing is, if you've got 9v AC and you feed it into a transformer that will give 1A at 9V, 0.08A at 110V will come out of the unit. Eight one-hundredths of an amp isn't really enough to do anything with. If you want to get 1A worth of 110v from 9v, you need to feed (assuming perfect efficiency in the transformer, which you will not get) 12.5A at 9v, or 25A at 9v if you have a transformer with a more likely 50 percent efficiency. It's possible to step 9v up to 110v, but it's probably not worth your time to do so.
If you have a 2 pole circuit breaker box and cannot get your 240V electric dryer to work should you place 30A on both sides of the box if you purchased a 30A receptacle that reads 125v250v?
Answer for trained people:There is one mistake that a knowledgeable person can make, and wonder why it doesn't work. This happens in some breaker boxes if you place a skinny 240 volt breaker filling an odd location (counting down vertically) and the next even position below that. When this happens, both hot lines are on the same leg. So, instead of 240 volts across the motor, you have no voltage across the winding, but the motor winding is entirely at 120 volts with respect to ground. The upper position of the breaker location must be an even position, and the lower position the next odd position. Most breaker boxes alternate bus legs in horizontal strips, not vertical rows. The first two horizontal rows are on leg 1 (L!), the next two horizontal rows are on leg 2 (L2), the next two rows are leg 1, etc. This requires placing a double pole breaker where it spans both legs L1 and L2.The following condition will occur if you have duplex breakers installed in your panel. This error happens most often when the number of breaker positions already used in the box is a multiple of 4, and you try to use the next available space on one side. The next two spaces on one side both have the same leg, so you can't put a 240 volt breaker there. But some of the boxes let you install it there anyway (mine has plastic bosses that prevent this).You can use a voltmeter to check for this. If you measure 120 volts from each hot prong to ground, but no voltage between the hot prongs, this has happened. A neon voltage tester will show no voltage between the hot prongs, even though it shows voltage from hot to ground.The cure is to move the breaker down one breaker space in the breaker box. You can put another 120 volt breaker in the empty space where the knockout was removed (since cover is required, and the knockout can't be put back), and reserve it for a future 120 volt circuit. (Since my box has wide knockouts, I had to install two dummy 120 volt breakers, one above the 240 volt breaker, and one below it. But they quickly found uses in extra 120 volt circuits.) NEVER use two single pole breakers for a 240 volt circuit, unless the handles are common tied together with a special device made for that purpose.
