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.


What is the best Electric wall heater voltage?

The higher the voltage the better since it means less current and therefore smaller wire size for the same wattage. The higher the voltage the better since it means less current and therefore smaller wire size for the same wattage.


What efficiency difference 240v 120v baseboard heater?

240V baseboard heaters are usually more efficient than 120V baseboard heaters in terms of energy consumption because they require less current to produce the same amount of heat. This can result in lower heating costs. However, the actual efficiency also depends on the insulation of the room and the overall heating system.


Can you run your neon sign of 120v 50hz 60hz 0.6a 7.5kv 30mA in an Australian 240v power outlet?

No. The neon sign is fed by a step-up transformer. Primary side 120V, secondary side 7500V. If you applied 240 to the primary side you would get 15000 volts on the neon tube. A flash over and then nothing. If you can find a transformer from 120V to 240V or 240V to 120V then you are good to go. Connect 240V to 240V side and you will get 120V out the other, connect the 120V side to the neon sign and you should have light. Transformer should be at least 100va. This will give you an output of .83 amps at 120V


277 volt heater runs on 240 volts?

Yes and No. A 277 volt heater uses 1 "hot" wire and a neutral, And 240 volt uses TWO hots (120 volts each) and NO neutral unless it has a 120V blower unit just to get that out there. Theoretically you could use 240 volts. Because 240 volts is a Lower (and there are also heaters 120v Hot to Neutral btw) voltage you would Decrease the wattage output of the heater itself which would violate the UL rating of the heater. Here's the Math. Rated Voltage x Rated Amperes = Rated Wattage Output. So if you have a 1500W unit @ 277V it draws 5.41A. Now that you know that you take Ohms Law to find the total Resistance of the Unit which would be 277A / 5.41 = 51.1 Ohms/Resistance. If you take Ohms Law again but for Amperes and factor in 240V instead the math would be 240 / 51.1 Ohms =4.69A. Now take 240V x 4.69A = 1125Watts. You can see that the output is way lower then the maximum rating of the heater. This is for purely resistance heaters like baseboard and and Ceiling Tile heaters. None the less if you installed this on 240V and it is not UL or CE listed for it you violated the rating and the National Electric Code. If you want a better idea look at 240V heaters most are Dual rated for 240V and 208V and you will see the same difference in output wattage listed on the unit.

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.

Can a 120V chandelier be hard-wired to a 240V power source in Europe using 240V bulbs and will the wires handle the load?

as long as the total WATTAGE of the bulbs is the same, you should get the same light and the wires will handle the load just fine.


Can 240V washer run on 120V outlet?

No.


Why are you not getting 240v between the two hot wires?

Because they are "in-phase". In order to get 240v, you need two 120v Alternating Current lines that are 180° out of phase, that is, opposite phases. Only when one line is +120v and the other -120v will you see 240v between the wires.

Does a pool pump on 220 volts use the same amount of energy as a 110 volt?

Assuming it is also rated for 120V., yes. The wattage doesn't change with an increase or decrease in voltage. However, the current draw does. When you double the voltage a load is hooked up to, the Amperage draw (current) drops in half. Example: if a 240 volt heater draws 6 amps, it will draw 12 amps if connected to 120V. If a 120V heater draws 15 amps, it will draw only 7.5 amps when connected to 240V. But power, or wattage stays the same, regardless. And this is what is used to calculate energy usage and therefore, cost. Please note the above answer says "if it is also rated for"
