How do you change a heater from 120 volts 3a to 240 volts 1.5 a?
the simplest solution is by connecting two 120v 3amps heater in series , the same can be used directly on 240v. However the current drawn will still be 3 amps & Not 1.5 amps. The heater output power will be double that of a single heater running on 120v. ( or equvalent to two heaters operating on 120v. supply ) A more expensive method is to use a stepdown transformer which can be powered on 240v & connect the heater on the transformer 120v side. this method will consume approx. 1.5 amps from the 240v supply.
How many amps are generated by a 1500 watt heater at 208 volts?
You have to be careful here. A heater will be advertised as "X" watts, but that is only true if you connect it to the voltage source it is supposed to be connected to. If you plug it into a higher or lower voltage source than intended, it will produce a different number of watts.Electric heaters are just resistors. When you run electricity through them, they get hot. If you run more electricity through that resistor, it will produce more heat. If you run less electricity through it, it will produce less heat.As an example, you can find "1500W/120V" water heater elements at the hardware store. This means that if you plug it into a 120V source, it will produce 1500W of heat, and it will pull 1500W/120V = 12.5A of current.You can calculate the resistance of the heater by taking voltage times voltage divided by watts, so this "1500W/120V" heater is really just a resistor of this many Ohms:120V * 120V / 1500W = 9.6 OhmThat Ohm value is physical property of the device. It will not change. If you were to take this heater now and plug it into a 240V supply, you can calculate the amps with voltage divided by resistance:240V / 9.6 Ohm = 25 AmpsAnd, for watts, you can take voltage times voltage divided by ohms:240V * 240V / 9.6 Ohm = 6000WSorry for the long text, but it's crucial that you understand this.If your heater is 1500W and is INTENDED to be running on 240V, you have a 38.4 Ohm resistor. Running that resistor at the lower 208V will produce only 1126W of heat and will pull just 5.4 Amps of current.However, if your heater is 1500W and is indented to be running on 120V, then you have a 9.6 Ohm resistor. You will almost certainly start a fire if you plug it into a 208V supply, because you will be pulling close to 22 Amps and producing 4500W of heat.
Will 2500 generator run a laminating machine 240v 10a 50hz?
Yes. 240 volts at 10 amps is 2400 watts. The generator is 2500 watts maximum. If the generator is 2500 peak power it may not run it very long. If the continuous power rating is at least 2400 watts it should be OK.
Will 240v heater work with 220v output?
It should work fine, you'll just get a less power dissipated (and therefore heat) than you're expecting.
How do you change 220volts to 240 volts in panel?
You shouldn't have to, 220 and 240 volts are a nominal figure in the same voltage range. It is brought about by the power company, as they have a responsibility to keep voltages within a certain 10% range. The load will only notice a difference of 1% on the load current. e.g. Wattage load of 2400. Amps = watts/volts. 2400/240V = 10 amps. 2400/220V = 10.9 amps. On a constant resistance as the voltage goes lower, the current goes higher and vice versa as the voltage goes higher, the current goes lower.
Can you use one wire from the panel with 240v on it to wire a 240v water heater?
In North America it takes two "hot" wires to obtain 240 volts.
A 208V water heater can te be replaced by a 240V water heater?
Yes but you will not get the full watt rating out of the tank. Watts = amps x volts. Say the tank draws 20 amps. 20A x 240V = 4800 watts. 20A x 208V = 4160 watts. It will take longer to heat your water with less wattage.
You are building a new house and trying to decide between 120v and 240v which is better More practical?
In the US, both 120v and 240v will be needed for your home, as different appliances need different voltages. Your TV needs 120V, while your electric dryer and stove will need a 120V/240V supply. If you have an electric water heater, or central AC unit, they will need a 240V supply.
IS there an adapter for a 240V heater that will allow you to plug it into two 110V outlets?
No. Sounds like a fairly hazardous thing to try as well. If it's to use a heater in the US, then buy a US heater at a lower cost than any adaptor that might do the job for you. If it's to use on a UK building site that has 110V but doesn't have 240V, it breaks all the rules because you end up with 240V where you shouldn't.

You want to fit a heater in a outhouse from a domestic 240v supply the cable has a resestance of 1.5 ohms and the heater has a resistance of 28.5 ohms what is the voltage drop in the cable?

How can you get 240V single phase power from a 240V 3 phase service Can you just connect to two poles of the 240V 3 phase service?
I'm sure this isn't what you want to hear, but you probably need to ask an electrician familiar with your service and what you want to connect. As a general answer, you can connect a 240v line to line resistive load like an electric water heater to any 240v source. If you also need the 240v to have 120v line to neutral, like a 240v electric stove that contains a 120v clock and oven light, then its possible if the 3 phase power is connected in a "high delta" configuration, and you connect to the correct leads. If you have a high delta service and want to ignore the 3-phase power service and wire most or all of the loads in the building as a single phase load, the utility may have to be consulted.

How can you convert a 3 prong 240V appliance outlet to 120V without rewiring and replacing the outlet?
For USA, Canada and countries running a 60 Hz supply service.1) An outlet for 240V is totally different from a regular 120V outlet. 2) The wiring for 240V is also much heavier than for 120V.3) The double pole circuit breaker necessary for 240V is different to the single pole breaker used for 120V.4) Anyway it is not clear why you would want to try to change a 240V outlet to a 120V type?5) If you could log in and add some more details below here so we knew your reasoning for wanting this change to take place, someone may be able to assist you much further.The reason why I need to do this is because there is only one 3-prong 240V outlet in the water heater closet feeding an inline water heater and I want to install an instant hot water recycling system which runs on 120v I so need the extra power outlet.If you want to keep the existing 240V water heater then you cannot add another outlet to the circuit, not even a 240V one, let alone a 120V one!The wiring and its circuit breaker is only rated to carry the current for one water heater and nothing else. If you add another appliance to the circuit you risk causing a house fire: the breaker may buzz but not trip so that the wiring gets hotter and hotter until something catches on fire!So, if you are planning to buy a new hot water recycling system it surely deserves to be installed safely and correctly?So why not, for your instant hot water recycling system, have a licensed electrician install a separate 120V circuit with the correct breaker, the correct-sized cable and the correct outlet near to the existing 240V outlet?As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
